| This paper studies access to, and adoption of improved seed, as well as the diffusion of improved seed information in a remote area of central Madagascar. The analysis is based on panel data gathered from 2012 to 2014 from 390 households in three villages. In 2013, a randomised control trial was applied. Half of the 390 households were randomly assigned to receive improved lima bean seed (Phaseolus lunatus), which were specifically bred for dry regions. Of the seed-receiving households, 50 % were randomly assigned to receive information on how to store, plant, and cultivate the improved seed, as the variety was unfamiliar in the region. The control group and the two treatment groups are compared with respect to baseline characteristics, bean cultivation,... |

| This research was conducted to evaluate the agronomic characteristics and chemical composition of Gliricidia sepium (Jacq.) Steud grown under different residual heights in different seasons. The experimental design used was a complete randomized block in a split-plot. The plots consisted of three residual heights (70, 90 and 110 cm), and the subplots were four seasons (fall, winter, spring and summer) with four replicates. There was no (P>0.05) interaction between season and residual heights for agronomic characteristics. However, these features were influenced by the cutting season, with no significant effect (P>0.05) on residual height. Significant effects (P<0.05) were observed for dry matter, mineral matter, acid detergent fiber and... |

| Melatonin is an environmentally friendly-molecule with a potent free radical scavenger and antioxidant capacity. Two pot experiments were conducted during two successive winter seasons (2011/2012 and 2012/2013) at the wire-house of the National Research Centre, Dokki, Cairo, Egypt to study the potentiality of melatonin (100 mM and 500 mM) in alleviating the harmful effect of diluted seawater at a relatively low and high concentrations (3.85 dS/m and 7.69 dS/m, respectively) on the performance of faba bean plants. The results revealed that irrigation of faba bean plants with diluted seawater reduced growth parameters (plant height, leaves number/plant, fresh and dry weights of plant), relative water content (RWC), photosynthetic pigments (chlorophylls a, b... |

| RESUMO: Este trabalho objetivou avaliar a influência de sistemas de preparo de solo e de rotação de culturas e pastagem na abundância e dinâmica de artrópodes edáficos. O experimento, instalado em Planaltina, DF, foi composto por 17 tratamentos que corresponderam a sistemas de preparo de solo (convencional e direto) e a rotação de culturas, pastagem e vegetação nativa (Cerrado). Realizaram-se amostragens de solo em três profundidades (0-5 cm, 5-10 cm e 10-20 cm) e em quatro épocas do ano (fevereiro, maio, agosto/setembro e outubro/novembro) entre 2003 e 2006. Os artrópodes foram extraídos em funil de Berlese-Tüllgren e identificados com relação à ordem. Coletaram-se artrópodes pertencentes a três classes: Insecta, Arachnida e Collembolla. Observou-se que... |

| tThe regular water supply during life cycle is essential to determine the yield in the legumes. In semiaridenvironments, the irregular rainfall and high temperature influence the phenology of crops impairing theyield. Peanut is an oleaginous crop with broad adaptation to tropical and semiarid climates, but yield isoften harmed when plants face water irregularities during reproductive phase. The recommendation ofcultivars tolerant to environments with water?limitation is indispensable to farmers in order to ensurereasonable production when drought settles down. Here, we evaluating peanut bred lines in order toassess drought tolerance based on physiological and yield traits, in greenhouse and field assays. In green-house experiment, 2 genotypes (BR 1,... |

| A cobertura morta do solo com leguminosas e gramíneas e urna prática cultural que traz benefícios aos sistemas de produção. Foi conduzido urn experimento no município de Seropédica, estado do Rio de Janeiro, com o objetivo de avaliar o efeito de diferentes tipos de cobertura morta sobre a reinfestação de ervas espontâneas e sobre o desempenho agronômico de alface, em cultivo orgânico. 0 delineamento experimental adotado foi blocos casualizados com quatro repetições e parcelas de oito plantas na área útil. Os tratamentos foram: bagaço de cana-de-açúcar (Saccharum sp.), bambu (Bambuza sp.), capim Cameroon (Penisetum purpureum), crotalaria (Crotalaria juncea), eritrina (Erythrina poeppigiana), gliricidia (Gliricidia sepium), guandu (Cajanus cajan), mucuna... |
