A data acquisition system for sprinkler uniformity testing
(Amer Soc Agricultural EngineersSt JosephEUA, 2000)
Hydraulic performance of new and used self-compensating micro-sprinklers
From the technical and economic perspectives, it is imperative that irrigation systems have extensive durability and high uniformity of application. The objective of this study was to compare the hydraulic performance of ...
Soybean response and ion accumulation under sprinkler irrigation with sodium-rich saline water
(Taylor & Francis Inc, 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 ...
Yield of upland rice cultivars in rainfed and sprinkler-irrigated systems in the Cerrado region of Brazil
(CSIRO Publishing, 2006-01-01)
In upland rice, the reduced grain yield that originates from the moisture stress period is related to the plant's tolerance of water deficiency and may vary between cultivars. The purpose of the work presented here was to ...
Efficiency improvement in linear‑move sprinkler systems through moderate runoff–runon control
(Springer Verlag Berlín, 2015-01-28)
Given the importance of achieving substantial water and operation savings, automated irrigation management has evolved toward integration of soil moisture measurements with simulation models. The main objective of this ...
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
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 ...
Avaliação de desempenho do microaspersor amanco em bancada de testes
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 ...
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 ...
