Produção de matéria seca em pastagem de Tifton 85 irrigada, com diferentes doses de dejeto líquido de suíno
(Associação Brasileira de Engenharia Agrícola (SBEA), 2006-08-01)
O dejeto líquido de suíno (DLS) pode constituir-se em excelente fonte de adubação em pastagem, com aplicação por aspersão, desde que seja assegurada a proteção do meio ambiente. Apesar de seu comprovado potencial para uso ...
Flow rate sprinkler development for site-specific irrigation
(SPRINGER, 2011)
Due to the rapid depletion of water resources, water must be used more efficiently in agriculture to maintain current levels of yield in irrigated areas. The efficiency of irrigation systems can be increased by adjusting ...
Soybean response and ion accumulation under sprinkler irrigation with sodium-rich saline water
(Taylor & Francis, 2013-04)
The magnitude of crop growth and yield depends on the salinity level, the toxic ions present in the irrigation water and the irrigation system used. In order to study the effect of sprinkler irrigation with salty water on ...
Avaliação de desempenho do microaspersor amanco em bancada de testes
(2008-07-01)
The need for a rational use of water and supply of food for a growing world population have led to the development of research in the area of irrigation systems. Thus, some irrigation systems which join efficiency with low ...

Manejo de solo e água em soja e arroz em terras baixas
(Universidade Federal de Santa MariaBrasilEngenharia AgrícolaUFSMPrograma de Pós-Graduação em Engenharia AgrícolaCentro de Ciências Rurais, 2019-03-11)
The lowland areas with agricultural production in the southern half of Rio Grande do Sul are predominantly cultivated with rice, flood irrigated. This irrigation method uses more water and emits larger amounts of greenhouse ...
Water supplied by sprinkler irrigation system for upland rice seed production
(Universidade Federal de Uberlândia (UFU), 2012-01-01)
Physiological quality of rice seeds may be influenced by water deficiency at seed development and filling stages, which is often reported in upland cropping system. This study had the objective of evaluating the effects ...

Response of rice cultivars to nitrogen in upland conditions
(2013-04-10)
Against the background of a growing world population, rice (Oryza sativa L.) consumption is expected to grow faster than its production. Therefore, an appropriate question would be: how to increase productivity in the ...
