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... |

The aim of this study was to calibrate the CENTURY, APSIM and NDICEA simulation models for estimating decomposition and N mineralization rates of plant organic materials (Arachis pintoi, Calopogonium mucunoides, Stizolobium aterrimum, Stylosanthes guyanensis) for 360 days in the Atlantic rainforest bioma of Brazil. The models´ default settings overestimated the decomposition and N-mineralization of plant residues, underlining the fact that the models must be calibrated for use under tropical conditions. For example, the APSIM model simulated the decomposition of the Stizolobium aterrimum and Calopogonium mucunoides residues with an error rate of 37.62 and 48.23 %, respectively, by comparison with the observed data, and was the least accurate model in the... |

El objetivo del presente estudio fue conocer el potencial nutricional para la alimentación animal de cinco especies de Lupinus (L. montanus, L. exaltatus, L. campestris, L. hintonii, y Lupinus sp.). Plantas completas en floración (componente follaje) y fructificación (componentes: vainas y semillas) fueron recolectadas en la Región de Valles y Libres del Serdán, Puebla, durante julio y agosto de 2010, a una altitud entre 2486 y 3442 m. Los análisis realizados por componente fueron proteína cruda (PC), extracto etéreo (EE), cenizas (Ce), fibra detergente neutro (FDN), fibra detergente ácido (FDA), alcaloides totales (Alc), polifenoles totales (Pt), taninos condensados (Tc), degradación in situ de MS, MO, PC, FDN y FDA, composición mineral de semillas y su... |
