Hydraulic performance of new and used self-compensating micro-sprinklers
(2015-11-01)
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 ...
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 ...
A data acquisition system for sprinkler uniformity testing
(Amer Soc Agricultural EngineersSt JosephEUA, 2000)
Sistema web de manejo da irrigação - SISMI
(2015-01-01)
As the current water management methods are difficult to apply and relatively high cost for low-income irrigators, this study aimed to develop a low cost single application SISMI (Web Management System of Irrigation), for ...
Software “slide” for sprinkle irrigation lateral line designSoftware slide para dimensionamento de linhas laterais em irrigação por aspersão convencional
(2019-01-01)
Sizing conventional downhill sprinkler lateral lines requires careful consideration, as the pressure distribution profile along the line can take different configurations depending on the slope of the terrain. The objective ...
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 ...
Assessing low-pressure solid-set sprinkler irrigation in maize
(Elsevier, 2017-09)
Water and energy are limited and expensive resources. Conserving water and energy is a requirement to ensure the viability of modern pressurized irrigation systems. The objective of this research was to analyze the ...
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 ...
