title: Organic fertilization and forms of application in Allium cepa growth, yield and bulb quality

description: ABSTRACT Onion is the third most cultivated vegetable in Brazil, and organic fertilization can increase its productivity. The objective of this study was to evaluate the effect of doses of cattle manure and forms of applications on the growth, yield and bulb quality of onion cv. IPA-11 Vale Ouro. The experimental design used was randomized blocks, with four replicates, in a 6 × 2 factorial scheme, corresponding to six doses of cattle manure (0; 10; 20; 30; 40 and 50 t ha-1) and two forms of application (incorporated and topdressing). The onion growth increased with cattle manure doses. Using cattle manure fertilization is feasible for the production of onion, however high doses, regardless of the form of application are not recommended. Incorporated manure increases the leaf concentrations of primary macronutrients in onion and promotes 15 and 20% increment in total and marketable yield, respectively. The cattle manure incorporated into the soil increased the production of bulbs within the class of greater acceptance by consumers.

title: Extreme values of ET0 at Piracicaba, Brazil, for designing irrigation systems

description: ABSTRACT Irrigation system capacity is typically defined by analyzing probabilities of non-exceedance of evapotranspiration. The use of mean monthly values of ET0 may lead to underestimation of the required capacity, whereas use of maximum daily values may result in overestimation of required capacity. This study had the following objectives: (1) to analyze a 30-year series of daily ET0 data from Piracicaba, SP, Brazil, to evaluate the suitability of the Gumbel distribution for estimating the maximum values of ET0 organized in periods of up to 30 days; (2) to determine probable maximum values and to select ET0 values considering the irrigation interval and the risk of failure in terms of irrigation system capacity. Daily data from 1990 to 2019 were used to calculate ET0 using the Penman-Monteith model. The Gumbel distribution fitted to the data and was suitable for characterizing the frequency distribution of the maximum ET0. The probable ET0 for designing irrigation systems can then be estimated based on the expected lifespan, irrigation interval, and return period of ET0 maximum values. The higher the anticipated irrigation system lifespan, the higher the return period needed to attain a low risk of failure. Using the average of maximum ET0 values alone leads to underestimation of system capacity and a high risk of failure in terms of irrigation system capacity.

title: The use of volatile compounds as an alternative method in pepper breeding (Capsicum baccatum var. pendulum)

description: ABSTRACT: The aim of this study is to determine some fruit characteristics of 19 different lines hybridized by previous regular studies. These lines were examined in order to determine the differences among volatile components and reveal the differences in comparison with the parents. Plant height (cm), fruit weight (g), fruit width (mm), fruit length (mm), fruit flesh thickness (mm), pungency, immature fruit color and mature fruit color were determined of parents and F4 lines. As a result, a wide range of variations were determined between lines and parents in terms of all parameters apart from pungency. Especially in terms of volatile components, it has been found that some active substances are found only in the father and white genotype (Fenchol, spathulenol and geranyl acetate), some of them only in the mother and orange genotype (α-terpineol, dihexyl azelate and 2-hexadecanol). It was concluded that volatile compounds of the species can be used as a marker for breeding studies.

title: Barriers to Puberty Talk between Mothers and Daughters: A Qualitative Study

description: Abstract Objective The aim of the present study is to explain the barriers to puberty talk between mothers and daughters. Methods In the present study, the conventional content analysis method was used. The present study was conducted from September 2018 to August 2019 in Iran. The study population consisted of mothers and adolescent girls. The data was collected using purposeful sampling method. The sample consisted of 4 mothers and 6 girls that were interviewed using semistructured interviews. Data collection continued until data saturation was achieved. Data analysis was conducted as described by Graneheimet al. using NVivo 11 software. Results In the present study, after exploring the views of the participants about barriers to puberty talk between mothers and daughters, one dominant theme emerged. Puberty talk is seen as an “inappropriate talk with a girl.” There were several subthemes, including “lack of mother’s awareness regarding the school role, the busy schedule of the mother, and the adoption of alternatives to mother’s talk with girls”. Conclusions Different sociocultural factors affect puberty talk between mothers and adolescent girls. It is important thatmothers and policymakers take these barriers intoaccount.

title: Use of aquatic macrophytes as ecological solution for improvement of the water quality

description: Abstract A study was conducted at the Bodocongó lake, in Campina Grande city, Paraíba state, Brazil, to analyse the efficiency of aquatic macrophytes in the reduction of nutrient concentrations, organic matter and microbiological pollution indicators. Monitoring, was done at four collecting stations situated at two stream entrance points (one an the easteren side and the other one an the westeren side) and two points in the same areas inside the lake after water had passed through the macrophytes bank in the dry and rainy seasons. Accentuated reductions in the parameters were verified at the monitored points after the passage of the streams through the two macrophytes areas. The greatest reduction of N-NH3 happened at the easteren side (&gt; 78%) and N-NO3 at the westeren (42%). Ptot reduction was between 23 and 86% and PO4 -3 between 8 and 76%. High BOD (89 to 95%) reduction was noticed, and CTerm reductions varied between 35 and 98% while EF, between 35 e 88%.

title: POPULATION DYNAMICS OF Hypothenemus hampei (Coleoptera: Scolytidae) IN AGROFORESTRY AND MONOCULTURE SYSTEMS OF CONILON COFFEE IN THE SOUTHERN PORTION OF THE STATE OF AMAZONAS, BRAZIL

description: ABSTRACT Hypothenemus hampei is the main coffee pest in the Amazon and worldwide. Although coffee cultivation exists in the State of Amazonas, there is no information regarding the behavior of this species population in this region of Brazil. Since the Amazon region is a favorable environment for H. hampei, the present study aimed to investigate this insect population in the following cultivation systems implanted in the municipality of Humaitá, Southern Amazonas: i) coffee in native forest (CNF), ii) coffee intercropped with cupuaçu and açaí (native Brazilian fruits) (CCA) and iii) coffee in monoculture (MC). Also, the climatic and phenological parameters of the plant were used in relation with the population dynamics of the insect. For that, ten baited traps were installed in each field for the monthly sampling of the H. hampei population from July/2018 to June/2019. The highest population abundance of the insect was observed during the coffee flowering season, mainly in monoculture crops, when compared to the other intercropped fields. The total mean value of the insect population observed in the three environments evaluated was highest in August/2018, with a recorded value of 1749. The increase in rainfall indexes occurred simultaneously with a decrease in the insect population; this coincides with the end of the flowering season (October/2018, 161.8 mm) and the beginning of grain formation (November/2018, 234.8 mm). The lowest abundance of the insect observed in the coffee fields in native forest, with an abundance of 83 (CNF), indicates that the local biodiversity disfavors the population size of the pest in the environment. These results suggest that phenological phases of conilon coffee and the influence of climatic conditions can result in changes in the population dynamics of the H. hampei. Coffee agroforestry systems are more promising to maintain this population at low levels.

title: Growth and photosynthesis of young dwarf cashew plants grown under salt stress

description: Abstract Objectifying to study the responses of young cashew plants to salt stress, grafted dwarf cashew plants were irrigated with saline solutions of different electrical conductivities (ECs) applied either into the root environment or directly on the plant leaves. The electrical conductivities of drained water (ECds) practically doubled in relation to ECs, independently of the way that water was applied. Leaf Na+ and Cl- contents increased with increases of irrigation solutions, especially when applied on the leaves. When irrigation water was applied on the leaves, there were higher reductions in leaf area and leaf dry matter with salinity increase of the irrigation solution. Net photo synthesis was reduced linearly with the increase in salinity and this reduction appeared to be due mainly to stomatal limitations. The effects of salinity are more conspicuous when the irrigation solution was applied directly on the leaves, and the grafted plants appeared to acclimate better to salt stress if the saline solution was applied into the root environment.

title: Sanitary quality and production of lettuce production irrigated with treated domestic sewage

description: Abstract The use of treated wastewater in the agriculture provides water to soil and the vegetables, nutrients and organic material, which preserve the land and act as organic fertilizers; however, they might cause contamination of the final product. In the current research we studied the lettuce irrigated (Lactuva sativa L) with water from a well in land without fertilization (T1) and with mineral fertilization (T2) and compared the productivity and the sanitary quality of the lettuce irrigated with water from well and with organic manuring (T3), with fertirrigation made with effluents of treated domestic wastewater in polishing lakes (T4) and decanted influent (T5). The results showed better productivity during the two experiments in the treatment with reused water, being better in the lettuce irrigated with the T5 treatment. The T4 presented médium concentrations of termal tolerant coliforms within the recommendation of the OMS for irrestricted irrigation: ( &lt; 1.000 UFC 100 mL), &lt; helminthes egg L-1), although it presented higher pH values of all influents (8.7 and 9.0); The T5 was the only treatment with effluent which did not reach either microbiological or parasitological conditions for the irrestricted irrigation.

title: Germination and initial growth of two cultivars of castor bean under saline stress

description: Abstract Two castor bean cultivars (Ricinus communis L.), BRS-188 Paraguaçu (C1) and CSRN-367 (C2), were irrigated with five waters of different electrical conductivity levels (0.7, 2.7, 4.7, 6.7 and 8.7 dS m-1) in a radomized design with 3 replications and 5 x 2 factorial treatments distributions. Germination percentage, time and emergence speed index, plant height stem diameter, number of leaves and leaf area at 20, 40 and 60 days after planting were evaluated. Number of leaves and leaf area was higher in the cultivar C1 and a higher germination percentage and faster emergence were observed in the cultivar C2. Increasing salinity reduced germination percentage, made the emergence slower and diminished all the growth characteristics analyzed.
