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...
A line source sprinkler was used to irrigate corn (Zen ?nays L.) plots with potato (Soianum tuberosum L.)-processing wastewater in 1979, 1980, and 1981. Nitrogen applications ranged from about 4 to 600 kg/ha. Corn yields were measured for each row, the grain and stalks were analyzed for total N, and N uptake was calculated. The plots were split by years, one-third of the area was fertilized wit...
the effects of irrigation methods, various levels of water and nitrogen fertilizer on quality of cotton were studied at hashemabad cotton research station of gorgan in 2008. the experiment was conducted in split-split plot design with three replications. irrigation methods of furrow and sprinkler were main plots, various levels of water of 0%, 33%, 66%, 100% and 133% were subplots plots and var...
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...
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 ...
Dairy manure increases the yields of dry bean (Phaseolus vulgaris L.) and spring wheat (Triticum aestivum L.) from eroded, furrow-irrigated soils and may increase corn (Zea mays L.) silage yield from steeper eroded areas under sprinkler irrigation. In a 2-year field study in southern Idaho on Portneuf silt loam (coarse silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid), the effects o...
