Da alma dos artistas e escritores: Coisa humana, demasiadamente humana?
Authors: Burnett Henry
Published: October 2017

Resumo: O artigo discute a hipótese de Paolo D’Iorio e Olivier Ponton, segundo a qual Humano, demasiado humano deve ser considerado o livro que instaura efetivamente a obra de Nietzsche. A chamada “fase wagneriana”, simbolizada por O nascimento da tragédia, deveria ser colocada em suspenso, por se tratar de um momento hesitante e sem continuidade.
A caminho de uma filosofia sem alma. Uma abordagem psicofísica sobre a crítica da subjectividade de Nietzsche
Authors: Gori Pietro
Published: October 2017

Resumo: A crítica à noção do Eu é um tema do pensamento de Nietzsche que pode ser contextualizado dentro do debate oitocentista sobre a psicologia científica. Esse debate encontra em autores como Friedrich Lange e Ernst Mach dois pontos de referência importantes. Ambos perspectivam um desenvolvimento das ciências cognitivas em direcção a uma “psicologia sem alma” favorecendo assim um afastamento desta disciplina da velha metafísica da substância. No presente artigo nos referiremos aos autores encimados para compreender se e em que sentido Nietzsche pensa na necessidade de uma rejeição da noção de sujeito em filosofia.
Da questão filosófica à introdução de uma perspectiva: uma análise do problema do método em Husserl e Feyerabend a partir de Nietzsche
Authors: Azeredo Vânia Dutra
Published: October 2017

Resumo: Neste artigo propomo-nos mostrar que a formulação da questão filosófica, determinante de uma indagação acerca do mundo ou de algo a ele pertencente, é formulada desde uma resposta que se quer sustentar devido à adoção de uma perspectiva prévia. Em vista disso, utilizaremos o perspectivismo nietzschiano para compreender a diferença nas respostas de Husserl e Feyerabend ao método como problema.

ABSTRACT Assessment of groundwater contamination potential using geological, hydrological and hydrogeological attributes, is an efficient mechanism of sub-surface water resources protection and conservation. However, usually this method does not take into consideration the potentially polluting human activities, either in punctual or diffuse sources, or because the relative importance of the attributes are not considered. The paper proposes a multi-criteria approach as a way of solving this gap, reducing subjectivity and considering land use/cover due human actions influence in the process. The study was developed in Araras river watershed (Paraná Basin, Brazil) using rock, groundwater, relief, soils, and land use/land cover classification, employing multi-criteria analysis and data of contamination sources. The potential contamination classification showed the predominance (54% of the area) of very high and high potential, especially due to geological environment conditions (exploitation areas and groundwater recharge of the Itararé Aquifer - clastic sedimentary and free flow). The contaminant sources analyzed are located mainly in higher potential contamination areas.
Temporal dependence of potentiometric levels and groundwater salinity in alluvial aquifer upon rainfall and evapotranspiration
Authors: Fontes Júnior Robertson Valério de Paiva , Montenegro Abelardo Antônio de Assunção
Published: October 2017

ABSTRACT Rainfall uncertainty and high evapotranspiration rates in the semiarid regions not only play an important impact on surface water scarcity, but interfere on shallow groundwater quantity and quality. The aim of this study was to apply geostatistical methodology to analyze the time dependence of potentiometric levels and groundwater salinity in an intensively monitored alluvial aquifer upon agroclimatological variables, and thus investigate possible monthly and annual correlations. Statistically stable piezometers were considered for the temporal analysis, representing the mean behavior of the whole aquifer. It has been verified that stable piezometers for groundwater levels exhibited temporal dependence of 7 months, similar to the temporal scale of variation for monthly precipitation and potential evapotranspiration, which is consistent to the resulting crossed-semivariogram. Meanwhile, stable piezometers for electrical conductivity showed high uncertainty on temporal dependence scale, which ranged from 3 to 8 months. Thus, rainfall and evapotranspiration alone did not properly explain the temporal dynamics of groundwater salinity. The produced maps successfully identified the long term time pattern of groundwater variation, constituting an important support for water resources evaluation.
Quali-quantitative characterization of organic matter in urbanized drainage basins as a basis for the application of Water Resources Management Instruments

Published: October 2017

ABSTRACT The challenge imposed by law no. 9433/97 to establish mechanisms for the recovery of bodies of water led to a dynamic of research that could guarantee not only an adequate understanding of the management instruments but also the technical basis for their application. In this research, emphasis was placed on understanding the dynamics of organic matter (OM) in a drainage basin heavily influenced by anthropogenic activities, through the analysis and interpretation of qualitative and quantitative information. The case study was the Iguaçu River basin, from its headwaters in the Metropolitan Region of Curitiba (MRC) to the municipality of União da Vitória. The results obtained showed a large deposition of labile OM in the MRC coming probably from domestic effluents, with consequent DO depletion and water quality degradation. However, after the more urbanized region, there is a reduction in the concentration of OM and the indication of the predominance of pedogenic material, suggesting that in addition to the dilution effect, there is less input of anthropogenic effluents in this region, which results in an improvement in water quality, represented mainly by the recovery of the DO concentration. The combined use of quantitative data and UV-visible spectroscopy was fundamental to comprehend the variation in the characteristics of OM and its sources along the studied section.
Planning and implementing experiments and analyzing experimental data in vegetable crops: problems and solutions
Authors: Lúcio Alessandro Dal’Col , Sari Bruno Giacomini
Published: October 2017

ABSTRACT The statistical interpretation of experimental results is inherent to the research process. Therefore, every researcher is expected to have basic understanding on the subject. In vegetable crops, the planning, implementing and data gathering is more complex due to specific aspects related to this group of plants, such as intensive management and high labor requirement to carry out the experiments, uneven fruit maturation and heterogeneity of the experimental area. Since all these factors are sources of variability within the experiment, circumventing them in the experiment planning and implementing phases is fundamental to reduce the experimental error. Furthermore, the knowledge of statistical tests and the assumptions for their use is equally critical to make the research statistically valid. The present work presents the problems of unwanted variability within an experiment with vegetables and the possibilities to reduce and manage it. We discuss alternatives to reduce the variability due to uncontrolled effects within an experiment; the most common experimental designs; recommendation of appropriate statistical tests for each type of treatment; and techniques for the diagnosis of residues. We expect to contribute with researchers dealing with vegetable crops, offering subsidies to aid researchers in the planning and implementation of experiments and in the analysis and interpretation of experimental results.

Published: October 2017

Abstract Nutrient need in each development stage of plant is showed by nutrient accumulation curve; this is an important tool for fertilization recommendation. However, researches on vegetables with the objective to estimate these curves are scarce, mainly in the modern hybrids that show higher productivity potential and, probably, higher nutrient demand. In this study, the authors aimed to determine macronutrient accumulation of beetroot plants, hybrid Boro. The experiment was carried out in São Manuel, São Paulo State, Brazil. Five treatments {seasons of plant collection: 0, 14, 28, 43 and 60 days after transplanting (DAT)}, considering that in each season 16 plants were collected (four replications of four plants each, in a randomized block design). We evaluated dry matter accumulation, and nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulphur (S) in plant shoot and root. The period of the highest demand for most of macronutrients was from 29 to 43 DAT. The decreasing order of macronutrients exported by the roots of the beetroot was K>N>P>Mg>S>Ca (376, 232, 45, 29, 21 and 13 mg/plant, respectively), and accumulated by the whole plant (shoot + root) was K>N>Mg>Ca>P>S (709, 404, 126, 113, 69 and 50 mg/plant, respectively).

Published: October 2017

ABSTRACT Organic farming requires the production or use of certified seeds from the same cultivation system and, the information of potato cultivars adapted to organic production system is important. The objective of this work was to study the feasibility of utilizing sprouts of different potato cultivars, seed multiplication and yield potential in field conditions without using agrochemicals. Three experiments were conducted: the first experiment using sprouts as seed under protected cultivation in Guarapuava, Paraná State, Brazil, from November 2011 to February 2012; the second experiment was field conducted in Candói, Paraná State, from May to September 2012 and the third experiment was field conducted in Guarapuava, Paraná State, from February to May 2013. The experimental design was a randomized block design with 3 replications in all 3 experiments. In the 2 first experiments the following cultivars were evaluated: BRS Ana, BRS Clara, BRS Eliza, Crystal and Catucha, and in the last experiment Agata, Bintje, Baronesa and BRSIPR Bel were included. The traits analyzed were length of main stem, number of stems, number of leaves, fresh weight and number of tubers, percentage of infection by viruses and in the second experiment the incidence of late blight on leaves. In the third experiment, leaf area index (LAI), tuber, leaves and stem dry weights and late blight severity were also analyzed. In the first experiment, the cultivars showed differences in plant height and minituber production, the highest value was observed in cultivars BRS Clara and BRS Ana for plant height and cultivar BRS Clara for minituber production. In the second experiment, there was difference only in plant height, the tallest cultivars were BRS Ana and BRS Clara . There was low spread of viruses and, it did not directly reflect in tuber yield. In the third experiment the cultivars with lower disease severity were those recommended to organic farming, especially BRS Clara and Catucha; this second cultivar had the higher LAI and tuber yield, as well as resistance to late blight, factors that might have contributed to the recorded highest total tuber yield (13.8 t/ha).

RESUMO O gênero Capsicum, de grande importância mundial, ocorre tanto nos países tropicais como nos de clima temperado. De um total de 31 espécies, apenas cinco são consideradas domesticadas, as demais, semidomesticadas ou silvestres. Nos últimos anos, as pimentas passaram a ter maior demanda pelo mercado e, consequentemente, os trabalhos relacionados à caracterização, melhoramento e obtenção de novas cultivares receberam mais atenção dentro de instituições públicas de ensino e de pesquisa, assim como no setor privado. Este trabalho foi desenvolvido na Embrapa Hortaliças, com objetivo de caracterizar morfoagronomicamente linhagens de pimenta do tipo Jalapeño Amarelo, atividade essencial para o desenvolvimento de cultivares. Primeiramente foram identificadas três plantas segregantes da cultivar comercial do tipo Jalapeño Vermelho, que apresentaram frutos de coloração amarela. Com base nesse material, o trabalho foi desenvolvido em duas fases: na primeira, obtenção de linhagens homozigotas pelo método de Descendência de Uma Única Semente (do inglês Single Seed Descent); na segunda, caracterização das linhagens obtidas através de cinco descritores morfológicos de Capsicum propostos pelo IPGRI (1995) e posterior avaliação qualitativa das linhagens em campo, sendo usado o teste Scott-Knott para a análise estatística. Conclui-se que o método de melhoramento utilizado foi satisfatório, visto que, em 30 meses de trabalho, as linhagens avançaram cinco gerações (S5). A caracterização morfológica e a avaliação qualitativa permitiram identificar diferenças significativas entre as linhagens. As linhagens promissoras identificadas neste trabalho foram CNPH 25.368, CNPH 25.373, CNPH 25.374, CNPH 25.375 e CNPH 25.377.

Published: October 2017

ABSTRACT Ornamental use of Capsicum genus chili peppers has expanded due to easy seed propagation, short germination period, diversified fruit colors and harmony of potted plants. The ornamental plant sector requires cultivars adapted to different cultivation conditions in pots and gardens. Breeding programs can use heterosis and combining ability information, aiming to commercially explore hybrids or develop populations for lineage selection with desirable characteristics. However, the ornamental chili pepper field lacks studies with this data. In this study, combining ability of C. annuum accessions was determined for ornamental purposes and hybrid combinations were identified based on heterosis values. Fifteen hybrids were obtained from diallel crosses of six genotypes of C. annuum, from March to September 2014, under greenhouse conditions, grown in five-liter pots in experimental design of randomized blocks with 10 repetitions and one plant per plot. Morpho-agronomic characterization was conducted based on eight quantitative descriptors: plant height (before and after fruiting); canopy diameter; days to flourishing; days to fruiting; fruit length and diameter, and number of fruits per plant. Both additive and dominance effects play important role in controlling the studied characters, indicating hybrid exploitation as well as development of superior lineages from the progress of segregating generations. Negative heterosis values resulted in reduction in height, time for flourishing and fruiting, as well as fruit diameter and length, which are desirable for ornamental Capsicum breeding program. Considering an ideotype for ornamental chili pepper cultivars, the hybrids UENF 1626 x UENF 1750, UENF 1750 x UENF 2030 and UENF 1626 x UENF 2030 can be recommended for cultivation with ornamental purposes.

Published: October 2017

ABSTRACT The objective of this work was to analyze the growth of the Upiã tomato cultivar in the Vertical, Crossed Fence and Viçosa cultivation systems, in order to obtain explanations for the productive gains achieved in the Viçosa system. The experiment was conducted in Viçosa, Minas Gerais State, Brazil, from August 21st to December 5th, 2012, in the scheme of subdivided plots, being the plots represented by the cultivation systems: Vertical, using tape, 1.0×0.5 m spacing; Crossed Fence, staked with bamboo, 1.0x0.5 m spacing; and Viçosa, using tape, 2.0x0.2 m spacing. The subplots were composed by the sampling times of the plants: 15, 30, 45, 60 and 75 days after transplanting. The experimental design was in randomized blocks, with four replications. Each plot was composed by three lines of 10 plants, making a total of 30 plants per plot, being evaluated the four central plants of each plot. We evaluated the dry matter of leaves (MSF), stem (MSC), inflorescences (MSI), fruits (MSFr) and total (MST). Using the foliar area index, measured by digital scanners and the previously obtained dry masses, we determined the physiological growth indices: foliar area index (IAF), specific foliar area (AFE), relative growth rate (TCR), and net assimilation rate (TAL). The Viçosa system altered the growth pattern of the tomato, quantified by the growth analysis, in comparison to Crossed and Vertical Fences. The prolongation of the second growth phase for the dry matter of fruits could possibly explain the productive gains obtained in the Viçosa system. Additional studies are required in order to clarify the relationship between the duration of the second phase of fruit dry matter growth, the physiological indexes AFE, IAF and TAL with the size and fruit yield of the tomato.

Published: October 2017

ABSTRACT Strawberry is a crop of great economic and social importance. Its fruits are appreciated both for their flavor and nutraceutical potential. Some studies confirm that light quality influences plant physiology. Thus, the aim of this study was to investigate if changes in light spectrum, provided by low tunnels, can improve vegetative traits, as well as, production and fruit quality of strawberry. The authors used six tunnel covers (red, yellow, blue, green, transparent and opaque and one control, without cover), and two cultivars: a short photoperiod cultivar (Camarosa) and a neutral photoperiod cultivar (Albion). Experiment was evaluated in two seasons: production and plant development first; and then, post-harvest quality. Overall, Camarosa showed higher vegetative growth, lower production, and better fruit quality than Albion. Due to the complexity of physiological and biochemical responses, each trait evaluated showed a specific response to light changes. The red, blue, yellow and green covers did not show any significant improvement comparing with transparent and opaque covers. Thus, the authors suggest the use of the latter ones which have already been used commercially.

RESUMO Foi avaliado o efeito do volume de aplicação de hidróxido de cobre (HC) e do acibenzolar-S-metil (ASM) no controle da mancha bacteriana em tomate para processamento industrial. Os ensaios foram realizados em 2010, sendo um em Brasília-DF (ensaio 1), e dois em Morrinhos-GO (ensaios 2 e 3). Os volumes empregados foram 250 e 500 L/ha e as aplicações realizadas semanalmente, totalizando 13 aplicações. No terceiro ensaio, o número de aplicações do ASM foi reduzido para oito e as aplicações restantes foram feitas com HC. Após as duas primeiras aplicações, as plantas foram inoculadas artificialmente com Xanthomonas perforans (ensaios 1 e 2) e X. gardneri (ensaio 3). Foram avaliadas, de acordo com o ensaio, a severidade da doença, a produtividade e a relação benefício/custo para cada tratamento, tendo por base o incremento de produção em relação à testemunha não tratada. Em todos os ensaios, o volume de aplicação afetou a eficiência dos produtos, com maior redução da doença com aplicação de 500 L/ha. O efeito dos tratamentos na produtividade foi variável. Com base nos resultados do terceiro ensaio, com a aplicação de ASM-HC no volume de 250 L/ha, obteve-se a maior relação benefício/custo, seguido pelo tratamento com HC a 500 L/ha.

Published: October 2017

Abstract Little information on the comparative yield of the main potato cultivars (Solanum tuberosum subsp. tuberosum) used in Brazil is available. The objective of this study was to evaluate the performance of modern and old, European and Brazilian potato cultivars in different environments. Two experiments were carried in the field in 2013, in Brazil: in Guarapuava, in the state of Paraná, from January to April; and in Brasília, the Federal District, from August to November. Treatments consisted of six cultivars (origin, year of release): Bintje (European, 1910), Monalisa (European, 1982) and Agata (European, 1990); Baronesa (Brazilian, 1955), Catucha (Brazilian, 1995) and BRS Clara (Brazilian, 2010), arranged in complete blocks at random, with four replications, in both areas. Growth cycle, total and commercial yield (number of tubers and mass), tuber average weight and tuber dry matter content were evaluated. We observed significant differences in yield among cultivars, both in Guarapuava and in Brasilia. We also observed that increases in yield in Brazil are possible, the modern cultivars having higher yield potential than old cultivars. No significant differences in yield were detected between European and Brazilian cultivars, in none of the growing zones. We suggest that the use of imported cultivars by Brazilian potato growers is related to factors not associated to yield.

Published: October 2017

ABSTRACT Snap beans have been widely used in organic farming as a good income source and an alternative to diversify production, with increasing use in crop rotation. This work reports the evaluation of 25 bush-type snap beans accessions for their suitability to integrate a breeding program for organic farming, as well as for their resistance to the common bacterial blight (CBB). Agronomic performance was assessed in two field experiments (September-December, 2013; April-June, 2014), in complete blocks at random, while resistance to CBB was assessed in greenhouse, in a completely randomized trial. Plants were challenged with two isolates, one from Xanthomonas axonopodis pv. phaseoli and another from X. fuscans subsp. fuscans. Accessions UEL 402, UEL 405, UEL 407, UEL 408, UEL 412, UEL 417 and UEL 420 were highly productive in both seasons (averages of 10.3, 8.7, 9.5, 9.2, 8.9, 9.3 and 9.2 t/ha, respectively), and are promising for use both as cultivars by organic farmers in the region of Londrina and also as germplasm in breeding programs for developing cultivars adapted to the region. Although all accessions were moderately susceptible to CBB, accessions UEL 407, UEL 409, UEL 411, UEL 412, UEL 424 and UEL 431 presented the lowest values for the area under CBB progress curve for both isolates.

RESUMO O trabalho teve como objetivo avaliar os efeitos de diferentes doses de dióxido de carbono (CO2), aplicadas via irrigação por gotejamento na determinação da concentração de capsaicinóides nos frutos da pimenta cv. Tabasco (Capsicum frutescens) visando proporcionar frutos mais ardentes e maior produção dessas substâncias para o mercado de molhos picantes. Os tratamentos aplicados foram 0; 82,6; 92,6; 123,8; g CO2/L. O delineamento experimental utilizado foi de bloco casualizados com 4 tratamentos e 8 repetições. Foram coletados 20 frutos de pimenta na maturação máxima, porém antes do início do murchamento, apresentando cor vermelha nas colheitas, totalizando 12 amostras. Para cada amostra, foram analisadas duas repetições de capsaicina e dihidrocapsaicina. As análises foram realizadas por cromatografia líquida com detecção por ultravioleta no CROMA, na USP em São Carlos. A concentração de capsaicina nos frutos foi reduzida conforme a concentração de CO2 aplicado aumentava, até um valor mínimo de 297 mg/kg de fruto para 123,8 g CO2/L. O mesmo comportamento foi observado em relação à dihidrocapsaicina, com o mínimo de 108,46 mg/kg de fruto para 123,8 g CO2/L. Conclui-se que quanto maior a concentração de CO2 aplicado via água de irrigação por gotejamento, menor a concentração nos frutos das substâncias capsaicinóides analisadas. Entretanto, uma vez que a produtividade aumenta com o aumento das doses de CO2, o rendimento total dessas substâncias por planta foi maior, mesmo que não tenha proporcionado aumento da concentração desses capsaicinoides nos frutos.

Published: October 2017

ABSTRACT The recommendation for green manure (GM) in cropping systems still has little scientific support, with few studies addressing the effects of nutrient amounts from green manure on the growth and production of the crop. Our aim was to evaluate the effect of levels of Crotalaria juncea green manure on the growth, production, and efficiency of the use as well as the apparent recovery of N in broccoli crop. Seven treatments were established; the main with four doses of green manure: 0, 3, 6, and 9 t/ha on a dry matter (DM) basis, applied with 12 t/ha compost. The control treatments consisted of mineral fertilization, the treatment with 25 t/ha compost, and another as the absolute control. Comparatively, production under the absolute control was less than all other treatments with green manure doses and application of 12 t/ha compost. The production of plants grown with 25 t/ha compost was superior to that of plants grown with dose of 0 t/ha and similar to that obtained with 3 t/ha; however, it was inferior to those produced with doses of 6 and 9 t/ha green manure. The highest percentage of N recovered (REC N) by the broccoli plants was observed close to a dose of 3 t/ha green manure, with a maximum point of 37.90% (2.8 t/ha), while in larger doses of 6 and 9 t/ha showed estimated values of 31.91% and 20.49%, respectively. The physiological efficiency of the use of N (EFUN) showed an effect similar to apparent recovery of N (REC N), with higher EFUN from lowest to highest dose of green manure, that is, 3, 6, and 9 t/ha, with estimated values of 70.41, 62.45, and 26.02 g DM per g of N uptake, respectively. The mass amounts of applied C. juncea influenced positively on the growth and productivity of broccoli. The lower mass of applied green manure increases the physiological efficiency of the use of N with more apparent recovery of the applied N.

ABSTRACT The aim of this work was to evaluate, under the Cerrado conditions of Central Brazil, the effect of different amounts of water and nitrogen (N) on the production performance of hybrid squash Tetsukabuto. Five water depths were tested in 2008 (185, 265, 343, 408 and 477 mm) and four in 2009 (286, 360, 430 and 540 mm), using line source sprinkler irrigation. The doses of N (0, 50, 100, 150 and 200 kg/ha) were the same in both experiments. The experimental design was a split-plot strip block with three replications. Fruit productivity was affected by the interaction between water depths and doses of N. Higher marketable productivity was observed on plants cultivated with the use of 477 and 492 mm of water and 105 and 146 kg/ha of N in 2008 and 2009, respectively. Ninety-five percent of the maximum productivity was reached by using 422 and 442 mm of water and 62 and 96 kg/ha of N in 2008 and 2009, respectively. The soil water tension thresholds, associated with the water depths that enabled 95 to 100% of the maximum productivity, ranged from 24 to 55 kPa. Higher water use efficiency occurred for water depths of 334 and 423 mm and doses of N of 90 and 120 kg/ha in 2008 and 2009, respectively. The use efficiency of applied N improved with increasing water depth and decreasing dose of N. Density, total soluble solids content and fruit pulp yield neither were affected by water depths nor by the doses of N.

ABSTRACT Plant-growth promoting rhizobacteria are an alternative to increase the productivity, adding value to the productive system of crops like okra. We aimed to evaluate the agronomic characteristics of okra genotypes after seed microbiolization with nine strains of rhizobacteria. The experimental design was in randomized blocks, in a 2x10 factorial scheme, using two okra genotypes, cultivar Santa Cruz 47 and hybrid Dardo, nine strains of rhizobacteria, LEBM 103, 105, 109, 112, 118, 134, 135, 152 and 154 and one control (without microbiolization), with four replications. We analyzed number of fruits per plant (NFP), average diameter of fruits (DM), productivity (PDT); fresh mass of fruits per plant (MFFP) and average mass of fruit (MMF). The rhizobacteria strains LEBM 109, 112, 152 and 154 provided the highest values for MFFP (1202.7; 1086.5; 1158.2 and 1175.9 g, respectively) PDT (24.1; 21.7; 23.2 and 23.5 t/ha, respectively) and NFP (78.0; 69.4; 73.27 and 76.5, respectively) in relation to the other strains and the non-use of seed microbiolization of hybrid Dardo. For cultivar Santa Cruz 47, the rhizobacteria LEBM 105, 112 and 152 provided the highest values for MFFP (896.7; 769.0 and 762.2 g, respectively). Evaluating genotypes when using each rhizobacteria, for MFFP and PDT, only for LEBM 105, no difference among genotypes was noticed, so, we concluded that okra seed microbiolization with rhizobacteria may provide productivity gain with possibility to become a feasible technique. The rhizobacteria which are the most recommended for growing hybrid Dardo are LEBM 109, 112, 152 and 154, whereas for growing cultivar Santa Cruz 47 are LEBM 105, 112 and 152.

ABSTRACT The authors aimed to evaluate the behavior of lettuce (Lactuca sativa), cv. Solaris, submitted to mulching in open environment. The experiment was carried out from April to June 2012, in the experimental area at Universidade do Estado de Mato Grosso, in Tangará da Serra, Brazil. The experiment was conducted on the field, being the experimental design completely randomized with six treatments and four replicates. The treatments consisted of the mulching types: black polyethylene, white polyethylene, black TNT, white TNT, rice husk and one treatment without mulching (bare soil). The evaluated traits were plant and stalk diameter, length of the stalk, total and commercial number of leaves, total and commercial fresh matter. The use of mulching with white polyethylene and rice husk favored the production of lettuce in tropical environment, obtaining the highest averages for the production variables total fresh matter (322.55 and 304.80 g/plant, respectively), commercial fresh matter (276.74 and 274.54 g/plant, respectively), total number of leaves (26.4 and 25.7 leaves, respectively), number of commercial leaves (21.7 and 22.1 leaves, respectively) and stalk length (5.48 and 5.79 cm, respectively).

ABSTRACT In this study were evaluated gas exchanges, fruit production and fruit quality of tomato Santa Cruz Kada grafted onto different species of the genus Solanum, using two grafting methods. For the grafted tomato cultivation, the authors used a randomized complete block design, in a 8x2 factorial scheme, evaluating eight rootstocks: accessions of mini tomatos (0224-5, RVTC 57, RVTC 20 and 6889-50); wild tomato species Solanum habrochaites var. hirsutum (PI-127826); Solanum pennellii (LA716); Solanum sessiliflorum (cubiu); and tomato cultivar Santa Cruz Kada (self-grafting, control), and two grafting methods {cleft grafting (FC) and approach grafting (EC)}. The authors verified a significant interaction between rootstock x grafting method. The S. pennellii rootstock provided the best results for physico-chemical characteristics, when grafted using the cleft method. However, the same method, along with cubiu rootstock, presented lower fruit production. Considering the gas exchange and productive characteristics, S. habrochaites as rootstock for tomato Santa Cruz provided the best results for photosynthetic yield and water use efficiency, and for the commercial fruit production characteristic, both grafting methods, and for the average mass of commercial fruits when grafted using FC, with about 5.03 kg/plant and 163.5 g/fruit, respectively. In relation to the grafting methods, the cleft showed to be the most suitable.

ABSTRACT The purpose of this work was to evaluate the influence of cutting the apex of the main stem of marigold plants on floral capitula yield. The experiment was carried out in a randomized complete block design, with five replicates. The following removal stages of the main stem apexes were studied: control (without pruning), up to 10 leaves, up to 15 leaves and visible flower bud. Three harvest periods were also evaluated: July, August and September, composing a factorial experiment in a 4x3 arrangement. The diameter, number, fresh matter and the dry capitula were evaluated. The most significant effect of cutting the apex of the main stem on fresh and dry matter of the capitula was obtained when the technique was performed at the time the plants had up to 15 leaves and visible flower bud. The harvesting performed in September showed to be the most promising, since it presented the larger diameter, higher number and higher fresh matter and the dry capitula.

ABSTRACT At present, Brazil is among the world's largest tomato producers. This production is directed both for the industry and for fresh consumption. Among the different tomato groups, production of mini-tomatoes has grown in recent years because of their high commercial value and mainly greater price stability. However, there are few studies investigating the proper management of this group, as it is recent in the country. The aim of the present study was to evaluate the viability of mini-tomato hybrids in different training systems, in greenhouse conditions. The experiment was set as a randomized block design in a 2×2×4 factorial arrangement with two numbers of stems (one and two stems per plant), two training systems [conventional (vertical) and horizontal], and four hybrids [AF 18196 (Sakata Seed); AF 13106 (Sakata Seed); Nina (Takii Seed) and Cocktail Mascot (Agristar/Top Seed Premium)], with three replicates and four plants per plot in the usable area. The evaluated variables were production per plant, fruit weight, transverse and longitudinal fruit diameter, number of fruits per plant, number of clusters per plant, number of fruits per cluster, precocity, production cycle, chlorophyll index, soluble solids, and crop cycle. The most promising hybrids are AF 13106 (2.71 kg/plant), AF 18196 (2.63 kg/plant) and Mascot (2.38 kg/plant), managed with two stems (2.63 kg/plant), in the vertical system (2.94 kg/plant).

ABSTRACT Changes in plant architecture, such as apical pruning and harvesting at the right time, are management practices to obtain not only greater fruit production, but mainly quality and pungent fruits, preferred by the consumer market. We evaluated the effect of management of pruning and harvest seasons on growth, production and pungency of fruits conducted in the field. Nine seasons of harvest were studied {90, 101, 116, 131, 146, 161, 176, 191, 206 and 221 days after transplanting (DAT)} and two management systems (pruning and no pruning). The treatments were arranged in a factorial design (9x2) with split plot in a randomized block design with three replications. The agronomic traits analyzed were: height, chlorophyll, leaf area, soluble solids, number of fruits and pepper yield. The content of capsaicin and dihydrocapsaicin was determined using fruits harvested in two seasons (146 and 161 DAT) and in management systems (pruning and no pruning), in a factorial scheme (2x2), in a randomized complete block design with five replications. Growth and production traits did not differ significantly for pruning and no pruning managements, with an average of 71.8 fruits/plant and productivity of 429.7 g/plant. The agronomic traits were adjusted to the quadratic model. The maximum yield (529.09 g/plant) and the maximum number of fruits per plant (95.34) were estimated at 164.83 and 163.21 DAT, respectively. The use of pruning resulted in fruits with a higher content of capsaicin (363.89 mg/kg) and dihydrocapsaicin (198.27 mg/kg) at 161 DAT. Pruning management results in more pungent and better quality fruits for industry, and the maximum production of BRS Mari pepper was estimated at 164.83 DAT, important information for pepper producers, in order to schedule the harvests.

ABSTRACT The aim of this work was to evaluate the performance of advanced potato clones for plant vigor, tuber yield components and specific gravity. Two sets of advanced clones and two control cultivars broadly grown in Brazil were compared. The first set, formed by 11 clones, was evaluated in the spring season of 2010, and the second, constituted by six clones, in the autumn season of 2011, in Canoinhas, Santa Catarina State, Brazil. The design of both experiments was a randomized complete block with four replications of two rows of 10 plants each. Plant vigor, tuber yield components and specific gravity were evaluated. The data of each experiment were submitted to analysis of variance and grouping means. Plant vigor was highly influenced by the environment. In the first set, 2197-15 and CL02-05 were the best clones for tuber yield traits. ‘2197-15’ presented potential for processing and fresh market, with high plant vigor, whereas ‘CL02-05’ showed potential only for fresh market, and less vigorous plants. In the second set, again the outstanding clone was CL02-05.

RESUMO A necessidade de definir uma dose de nitrogênio agronômica e economicamente adequada para a cultura da batata doce constitui um desafio imediato. O objetivo foi avaliar doses de N sobre a produção de biomassa e produtividade de raízes tuberosas, bem como verificar qual a dose econômica para a cultura da batata doce. O trabalho foi conduzido de março a agosto de 2011 em São Cristóvão-SE. Foi utilizado o delineamento experimental de blocos casualizados com os tratamentos distribuídos em esquema fatorial 5x3, testando cinco doses de N (0, 30, 60, 120 e 240 kg/ha), empregando-se, como fonte de N a ureia e três clones de batata doce (IPB-052; IPB-075 e IPB-149), com três repetições. A cultivar comercial Brazlândia Branca (IPB-052) foi considerada como padrão. A colheita foi realizada aos 150 dias após o plantio. Todos os clones avaliados alcançaram valores superiores ao rendimento médio nacional de produtividade de raízes tuberosas (11,84 t/ha). A biomassa da parte aérea dos clones avaliados respondeu linearmente às doses de N utilizadas. A dose de 130 kg/ha de N proporcionou rendimento máximo de produtividade total de raízes tuberosas dos clones estudados.
