Abstract In the presented paper, we evaluated quality of work and economics use irrigation system consisting micro-sprinklers. The experiment took place on football field in countryside southwest Slovakia. original was replaced with a modern one, using control unit, rainfall sensor, in-ground distribution pipes consisted components forming main detailed equipment for irrigating an area 4,272 m ...
In the evaluation of the risk of pesticide leaching to groundwater, the soil surface is usually assumed to be level, although important crops like potato are grown on ridges. A fraction of the water from rainfall and sprinkler irrigation may flow along the soil surface from the ridges to the furrows, thus bringing about an extra load of water and pesticide on the furrow soil. A survey of the li...
In the 1980s, a special compound formula was developed to suit the demands of a fire sprinkler system for life safety applications. In 1984, the first BlazeMaster® CPVC fire sprinkler systems were deployed in the United States. Since then, BlazeMaster fire sprinkler systems have been performing so successfully that 50% of all NFPA 13 applications in the US are specified with BlazeMaster pipes a...
The paper is devoted to the study of deflector nozzles rain irrigation machines. selection parameters nozzle artificial sprinkler machines on a scientific and practical basis allows for correct organization ecologically safe irrigation. article presents results research short-distance with deflector.
In this study, the optimum irrigation depths for corn grain production under different conditions, i.e. maximum grain yield production and maximum benefit under limited land and water conditions, were determined under sprinkler irrigation in Bajgah (15 km. north of Shiraz). The results showed that, the optimum depth of irrigation for maximum grain yield production was 77.0 cm. Because of low pr...
Peanut quality parameters were analyzed across four irrigation levels during the 2002 through 2007 crop years. The peanut quality parameters consisted of total sound mature kernels and sound splits (farmer stock grade), shelling outturn by commercial edible size, accept and reject kernels by commercial edible size, seed germination, and aflatoxin. The four irrigation levels consisted of a full ...
In this paper, an efficient irrigation system is proposed based on computing evapotranspiration (ET) and the required irrigation quantity using fuzzy inference methodology. The aim of this system is to schedule irrigation according to the particular requirements of a crop and to the change in various climatological parameters and other factors. This is to avoid overor under-watering which signi...
