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 ...
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 ...
EFFICIENT WATER APPLICATION ON SOIL SURFACE AND IN THE SOIL PROFILE IN A SPRINKLER IRRIGATION SYSTEM

Efeitos de níveis de cobertura do solo sobre a produtividade e crescimento do feijoeiro irrigado, em sistema de plantio direto
(2007-04-01)
The objective of this research was to study the effects of five different treatments of grass (Brachiaria decumbens) straw mulch on common beans (Phaseolus vulgaris L.): 0% (0 t.ha-1), 25% (2,25 t.ha-1), 50% (4,5 t.ha-1), ...
Economic viability and selection of irrigation systems using simulation and stochastic dominanceViabilidade econômica e seleção de sistemas de irrigação utilizando simulação e dominância estocástica
(2009-01-01)
In humid areas, irrigation systems are used to increase the crop yield. The selection of irrigation system to be used is a decision made under uncertainty. This paper shows a procedure that is an association between Monte ...
Data Acquisition System For Sprinkler Uniformity Testing
(ASAE, St. Joseph, MI, United States, 2000)
A Self-Powered and Autonomous Fringing Field Capacitive Sensor Integrated into a Micro Sprinkler Spinner to Measure Soil Water Content
(Mdpi Ag, 2017-03-01)
We present here the design and fabrication of a self- powered and autonomous fringing field capacitive sensor to measure soil water content. The sensor is manufactured using a conventional printed circuit board and includes ...
Performance and radial distribution profiles of a variable flow rate sprinkler developed for precision irrigation
(São Paulo - Escola Superior de Agricultura "Luiz de Queiroz", 2012)
Variable rate sprinklers (VRS) have been developed to promote localized water application of irrigated areas. In Precision Irrigation, VRS permits better control of flow adjustment and, at the same time, provides satisfactory ...
