| Grain must be transported from one location to another. Several disadvantages are associated with grain transportation, especially manual loading into trailers and silos. The need for a grain handling equipment became pertinent; hence, this study designed and fabricated a simple and medium size auger aimed at conveying grains upward into a silo. The conveyor was fabricated from pure local materials considering the techno – economic properties. Tests were run on the conveyor using granular materials like maize, sorghum and gari at 13% moisture content. The angles of test were 00, 150, 300, 450, and 600 for each grain. It was found capable of loading an average size silo of 2.68 m3 in 15 minutes. The conveyor has an efficiency of 99.95%, and average output... |

| Impact of postharvest and/or food processing (such as flour milling to agricultural and food-resource materials) on the digestibility of foodstuffs was investigated through a simulated gastro-intestinal in vitro digestion technique. The differences among the starch digestibilities of cooked rice grain and slurry were examined. In vitro digestion techniques are commonly applied to starch-based milled materials such as flours used for bread making. However, rice is not usually milled to flour but cooked as a whole for consumption. Therefore, maintaining an intact structure of cooked grain during in vitro digestion is very important to evaluate its starch digestibility. Two hundred grams of polished rice grain were cooked using electric rice cooker with 300... |

| ABSTRACT Brazilian off-season cropping is increasing the production of cereals, particularly in the Brazilian savannah. Sorghum has been widely used for its grain production capacity and dry matter. Several hybrids are commercially available, each with its own peculiar nutrient absorption capacity. Thus, this study analyzed the agronomic characteristics and nutrient exportation in grain sorghum hybrids sown on different dates. The experiment was conducted at the Paulista Agency Regional Center of Agricultural Technology (APTA) in the city of Votuporanga, São Paulo. The experiment was conducted in a randomized block design with four replications and 4 hybrids. Sorghum hybrids (50A10, 50A50, BUSTER and 1G282) were the different treatments sown on four... |

| Se ha desarrollado la metodología de estimación de alteración de algunas propiedades y un índice integral de fertilidad de los suelos irrigados de México atribuible al cambio climático global durante el siglo XXI. Esta metodología fue aplicada para evaluar la vulnerabilidad de la productividad de los cultivos de maíz de grano y trigo bajo riego en algunos distritos de riego de referencia del país ubicados en diferentes zonas climáticas. Los resultados de la investigación señalan que la sensibilidad de los suelos agrícolas bajo riego en México, al cambio climático, es mucho menor que los suelos de temporal y vírgenes y no afecta significativamente la vulnerabilidad de los cultivos de maíz y trigo bajo riego. Por lo general, los valores de cambio de... |

| El Se inorgánico en ovinos ha provocado cambios ruminales (pH, AGV y población microbiana) y en digestibilidad de algunos nutrientes; por lo que posiblemente estos cambios puedan influir sobre el requerimiento de Se para corderos en crecimiento. Por ello se realizó un experimento en dos cuadros latinos repetidos con arreglo factorial de tratamientos, usando 8 corderos (43.2 ± 4.7 kg de peso) con cánula ruminal y duodenal. Se midieron cambios en fermentación ruminal, digestibilidad de nutrientes y balance de Se provocados por la suplementación con selenito de sodio (cuatro niveles: 0, 200, 500 y 800 µg Se kg-1 MS) en dietas con 69 y 50% de grano de maíz. La concentración de Se en las dietas fue 220 ± 28 µg Se kg-1 MS. En líquido ruminal se observó:... |

| In corn, when the first female inflorescence is removed, the plant often produces new female inflorescences. This allows the first ear to be harvested as baby corn (BC) and the second as green corn (GC) or dry corn (DC), that is, mature corn. The flexibility provided by a variety of harvested products allows the grower to compete with better conditions in the markets. We evaluated BC, GC, and DC yields in corn cultivars AG 1051, AG 2060, and BRS 2020, after the first ear was harvested as BC. A random block design with ten replicates was utilized. The yields of MM, MV and MS were higher when these products were individually harvested than when they were harvested in combination with baby corn (BC + GC and BC + DC). Cultivar BRS 2020 was the best for... |

| Tendo-se em vista alguns aspectos extremamente favoraveis a utilizacao racional e ordenada do Cerrados, mormente naquilo que a natureza oferece graciosamente, entendendo-se que os principais fatores limitantes dizem respeito a corretivos, fertilizantes e distribuicao pluviometrica, a par de outros investimentos de capital representados por maquinaria, e entendendo-se tambem que isso nao e peculiar so aos Cerrados, mas ao Pais de um modo geral, nao ha duvida quanto ao acerto em colocar alta prioridade ao desenvolvimento dos Cerrados, mas nao sem antes considerar que o tratamento, isto sim, deve ser diferenciado. Em tais condicoes, fundamentalmente o que se recomenda e: a revisao e o fortalecimento do POLOCENTRO, como programa capaz de aportar 1) ciencia e... |
