title: TOMATOES USED BY INDUSTRIES HAVE TECHNOLOGICAL QUALITY FOR FRESH CONSUMPTION1

description: ABSTRACT The production of tomato (Solanum lycopersicum L.) for fresh consumption must overcome a challenge: the high production cost. The use of cultivars with determinate growth habit is an alternative to reduce costs. Thus, the objective this work was to evaluate the acceptability of tomato fruits from cultivars with determinate growth habit for fresh consumption. Seeds of 10 hybrids and one variety were grown in open field, arranged in six randomized block design, and tested for sensorial acceptability. The analyses were carried out using 50 not-trained consumers, considering their visual and sensorial preferences by affective methods and purchase intention. The hybrid Thaise grown with and without staking and the hybrid Gabrielle grown with staking had higher visual preference by the consumers, with frequency of 24%, 18%, and 22%, respectively, in the first position; and the hybrid Dominador showed higher frequency (18%) in the second and third positions; these hybrids had purchase intention above 80%. All hybrids and varieties had significant difference in the mean test at p&lt;0.05. The highest means found for Carrara, HM7885, Santa Cruz Kada, Asti, N901, Dominador, and Equatorial (appearance); Asti and N901 (color), Asti, Dominador, and Equatorial (aroma), and Santa Cruz Kada, Asti, Dominador, and Equatorial (flavor). Asti, Gabrielle (grown without staking), HM7885, and Equatorial had purchase intention above of 50%. The hybrids Ap533, Portinari, and Thaise grown without staking showed acceptability index lower than 70%. Plants with determinate growth habit produce fruits with acceptable visual and sensorial qualities for fresh consumption.

title: GERMINATION OF CREOLE MAIZE AND FAVA BEAN SEEDS UNDER SALT STRESS

description: ABSTRACT Salt stress negatively affects plant development, mainly in arid and semiarid regions, promoting changes in their physiology and productivity. The objective of this study was to evaluate the germinative potential of creole maize (Zea mays L.) and fava bean (Phaseolus lunatus L.) seeds under different salt stress conditions. The seeds were collected in rural areas of the municipalities of Guanambi, Candiba, and Brumado, which are within the Serra Geral region in the state of Bahia, Brazil. A completely randomized experimental design was used; the treatments consisted of three salts (CaCl2, MgCl2, and NaCl) and four salinity levels (osmotic potentials of -0.3, -0.9, and -1.2 MPa). Seed physical analyses included moisture and purity, and physiological analyses included germination percentage, germination speed index, average germination time, and relative germination frequency. The storage of creole maize and fava bean seeds in plastic bottles and under adequate humidity ensures that seeds will have moisture content and physical purity within ideal values. Salt stresses induced by NaCl and CaCl2 salts at osmotic potentials of -0.3 to -1.2 MPa hinder the creole maize and fava bean seed germination, and their germination are null for both salts at osmotic potentials lower than -0.3 MPa. The creole maize and fava bean seeds show germination of 70% under salt stress induced by MgCl2 at osmotic potential of -0.3 MPa, making the germination of both species viable.

title: AGRONOMIC PERFORMANCE OF ROCKET AS A FUNCTION OF PHOSPHORUS FERTILISATION IN A P-RICH SOIL1

description: ABSTRACT In intensive vegetable production systems, it is natural to increase nutrient contents in the soil due to the frequent fertiliser applications, especially phosphorus (P). There are few studies on the response of vegetables to phosphate fertilisation under such conditions. In this context, the objective of this study was to evaluate the agronomic performance of rocket as a function of phosphorus fertilisation in a P-rich Rhodic Eutrudox soil. Five P doses (0, 50, 100, 200, and 300 kg ha-1 P2O5) were evaluated in a randomised complete block design with four replicates. Maximum soil P content and shoot P content at harvest were obtained at a dose of 300 kg ha-1 P2O5. Rocket responded negatively to P fertilisation. The increase of P doses promoted the decrease of height and yield of the crop.

title: IDENTIFICATION OF PLANT PARASITIC NEMATODES IN TRIPLOID AND TETRAPLOID BANANAS IN BRAZIL

description: ABSTRACT Nematodes are important pathogens in banana plants, and the lack of resistant genotypes is the biggest challenge of the banana breeding programs. Little is known on the behavior of banana triploids and tetraploids developed by Embrapa regarding parasitism by plant-parasitic nematodes in field conditions. Embrapa Mandioca e Fruticultura experimental areas, naturally infested in five Brazilian states (Embrapa Acre - Acre, Embrapa Semiárido - Pernambuco, Embrapa Cerrados - Distrito Federal, Palmital - São Paulo and Epagri - Santa Catarina) were evaluated for the distribution and population levels of plant-parasitic nematodes in commercial cultivars and triploid and tetraploid genotypes in the final breeding stage. The root-knot nematodes (Meloidogyne spp.) were the most frequent in roots (40 - 100%) and soil (85.71 - 100%), with a detectable number of juveniles (J2) varying between genotypes (4 - 148 J2.250g-1 roots, and 1 - 110 J2.100 cm-3soil). Four esterase phenotypes were characterized: M. incognita (Est I1 = Rm: 1.0), M. javanica (Est J3 = Rm: 1.0; 1.25 and 1.40 and Est J2 = Rm: 1.0 and 1.40) and M. arenaria (Est A2 = Rm: 1.20 and 1.35), M. javanica (Est J3) was predominant. Meloidogyne javanica and M. incognita were predominant, however mixed infestations between species were found. The occurrence of Meloidogyne spp. was: M. javanica (68.26%), M. incognita (64.73%) and M. arenaria (16.81%). Helicotylenchus multicinctus and Rotylenchulus reniformis was the second most frequent group. Radopholus similis, Scutellonema sp., Criconemoides sp. and Helicotylenchus sp. presented themselves in low frequency and population levels in banana plants.

title: CHEMICAL DESICCANTS FOR ANTICIPATION OF HARVEST AND PHYSIOLOGICAL QUALITY OF COWPEA SEEDS

description: ABSTRACT Information about the effect of herbicides on cowpea seed quality is scarce. The objective of this work was to evaluate the effect of using chemical desiccants at pre-harvest on the anticipation of harvest and physiological quality of cowpea seeds of the cultivar BRS-Tumucumaque, before and after storage. Two experiments were conducted: experiment 1 was conducted under a randomized block design, with four replications; the treatments consisted of seven herbicides (carfentrazone-ethyl, saflufenacil, glyphosate, paraquat, flumioxazin, glufosinate-ammonium, and diquat) and a control treatment; anticipation of harvest, and seed water content, germination, and vigor were evaluated. The seeds were stored for six months in controlled environment and not-controlled environment rooms and evaluated for water content, germination, and vigor in Experiment 2, which was conducted in a 7^2+1 factorial arrangement, with four replications; the first factor consisted of the seven herbicides, the second factor was the two storage environments, plus a control treatment. The results showed 3 to 9 days of anticipation of harvest relative to the control. The glufosinate -ammonium herbicide negatively affected seed germination and vigor. The glyphosate herbicide decreased seed germination and vigor after storage. The physiological quality of cowpea seeds at the post -harvest period and after six months of storage was not affected by the carfentrazone-ethyl and flumioxazin herbicides. Paraquat and diquat were the most efficient herbicides for the anticipation of harvest (nine days). Glyphosate and glufosinate -ammonium were the most harmful herbicides to seed physiological quality. The controlled environment room was the most adequate environment for seed conservation.

title: COMBINING ABILITY OF GRAIN SORGHUM INBRED LINES GROWN DURING OFF-SEASON

description: ABSTRACT The expansion of sorghum as a succession crop, after soybean, has demanded the development of new inbred lines by the breeding programs. The first step in the selection process consists of evaluating the performance per se of the inbred lines or of their hybrid combination. The purpose of this study was to determine the combining ability of sorghum inbred lines under different environment conditions of the crop production areas. The trials were carried out in the second season of 2017, under no-tillage system, in four environments, Rio Verde, Sete Lagoas, Teresina and Sinop. Thirty hybrids, resulting from the crosses of six fertility restoration lines (R) with five male-sterile lines (A) were evaluated. A randomized complete block design with three replicates was used in all experiments. The characteristics evaluated were flowering, plant height and grain yield. The environment significantly influenced the estimates of general and specific combining ability, which suggests that both effects, additive and dominant, are important in the control of these characters. The restoring lines GI.1 and G1.2 contributed to increasing the grain yield of their hybrids by over 650 kg.ha-1. Among the male-sterile lines, the best for grain yield were GII. 1 and GII.4 with contribution above 450 kg.ha-1 in the hybrids in which they participate. The hybrid combinations GI.5xGII.3 and GI.1xGII.2 stood out with potential to obtain high grain yield, associating positive aspects of the other characteristics.

title: MACRONUTRIENT RATES AND MULTIFUNCTIONAL MICROORGANISMS IN A TROPICAL FLOODED RICE CROP

description: ABSTRACT Tropical flooded rice production systems require a high input of fertilizers and chemical defensive. The use of plant growth-promoting rhizobacteria (PGPR), a sustainable component of this system, can increase nutrient-use efficiency and lead to significant increases in the grain yield of tropical flooded rice crop. This study aimed to determine the effect of the microorganism BRM 32110 (Bacillus thuringiensis) in combination with nitrogen (N), phosphorus (P) and potassium (K) application rates on the physiological and agronomic performance of tropical flooded rice plants. Trials were performed in the 2016/2017 growing season in Formoso do Araguaia, a city in Tocantins state, Brazil. Three independent experiments (E1, E2, and E3) were performed in a randomized block design in a 4 x 2 factorial scheme with three replications. E1 comprised four N application rates (0, 40, 80 and 120 kg N ha-1) with and without the addition of BRM 32110, E2 comprised four P2O5 application rates (0, 40, 80 and 120 kg P2O5 ha-1) with or without BRM 32110, and E3 comprised four K2O application rates (0, 20, 40 and 60 kg K2O ha-1) with and without BRM 32110. In fertile soil, there were no interactions between the rhizobacterium BRM 32110 and the N, P or K application rates. BRM 32110 improved nutrient uptake and, on average, increased shoot dry matter by 8%, photosynthesis rate by 14% and grain yield by 11% in the flooded rice plants. Our results suggest that the use of multifunctional microorganisms is a good strategy for improving flooded rice grain yield sustainably.

title: GENETIC SIMILARITY OF Macrophomina pseudophaseolina ISOLATES ASSOCIATED WITH WEEDS IN THE BRAZILIAN SEMIARID REGION

description: ABSTRACT Macrophomina pseudophaseolina has recently been reported in association with weeds in melon producing areas in Northeastern Brazil. Species from this genus are the causal agents of root rot and vine decline (RRVD) in melon, reducing its productivity. It is needed to know the genetic variability of the pathogen to develop effective control methods. Thus, this work aimed to assess the genetic diversity among M. pseudophaseolina isolates collected from the weeds Trianthema portulacastrum L. and Boerhavia diffusa L. using ISSR and RAPD markers. For this, 41 M. pseudophaseolina isolates were submitted to amplification with five ISSR and ten RAPD primers. Genetic similarity was analyzed using the Jaccard’s coefficient and cluster analysis was performed by the UPGMA method. Combining data from both markers, the 41 isolates were separated into eight groups. Most groups were not arranged according to geographical origin and host of the pathogen. The genetic similarity among isolates ranged from 0.15 to 0.87. On the other hand, the highest genetic dissimilarity (85%) was observed between the isolate MpBr11, collected from T. portulacastrum in Icapuí (CE), and MpBr65, collected from B. diffusa in Assú (RN). Results obtained herein can assist breeding programs for the selection of resistance sources and the development of effective control methods against RRVD in melon.
