ABSTRACT One of the reasons for the success of a productive culture is the correct sowing. Therefore, the seeds must be properly dosed, deposited and not damaged by the metering mechanism of the seed drill. So, the aim of this study was to evaluate in a simulator the sorghum seed deposition by a metering mechanism with continuous flow in different conditions of slope and sowing speed, and evaluate the quality of the deposited seeds assessing mechanical damage and germination. The experiment was carried out at the College of Agricultural Sciences, UNESP in Botucatu-SP, being used a simulator equipped with seed metering mechanism of helical channelled rotor type. The experimental design was randomized in a 3 x 2 factorial arrangement with six replications.... |

ABSTRACT: In the Brazilian Central Region, flowering of Paspalum atratum cv. Pojuca is concentrated from mid February to mid March and seed maturation occurs from mid March to mid April, at the onset of the dry season. Use of combine harvesters is an excellent option Pojuca seed production areas because, besides this concentrated flowering and uniform seed maturation, this cultivar presents lon flowering stems which expose the seed heads above the plant canopy. Good agronomical practices regarding choice of the area, tillage, fertilization, seed bed preparation, seeding, weed control will assure the a high seed yield in Pojuca grass. Combine adjustments in the air flow, cutting height, cylinder rotation, and in the threshing and sieving apparatus will... |

A maior parte da produção de milho no Brasil ocorre em regime de sequeiro, tanto na primeira quanto na segunda safra, estando, portanto, sujeita a instabilidades climáticas que podem afetar o rendimento de grãos. Irregularidade no regime de chuvas, que induz estresse hídrico na cultura, é o principal fator responsável pela quebra da produtividade do milho no país. Algumas estratégias de manejo da cultura podem ser empregadas para atenuar este problema, entre as quais a escolha do período de semeadura adequado, preconizado no zoneamento de risco climático do Ministério da Agricultura, Pecuária e Abastecimento (Mapa). As ferramentas computacionais utilizadas no zoneamento necessitam, todavia, serem aprimoradas, principalmente em razão da nova era chamada... |
