Context Many regions in the world have undergone rapid land use change and intensification of agricultural land, such as through irrigation expansion, upgrading systems, changing grassland, stock, nutrient management practices. With more intensive use, changes to soil properties can occur, compaction water storage. The effects modern sprinkler-irrigated pastoral farming on physical are not well...

the purpose of this correlational research was to investigate the factors influencing satisfaction whith sprinkler irrigation systems (sis) as perceived by the adopting farmers. the research instrument was a structural questionnaire with close-ended questions, the validity and reliability of which were confirmed. the target population included all the adopting farmers who cultivated and harvest...

Better management practices can counter deterioration of ground water quality. From 1991 through 1996 the influence of improved irrigation practices on ground water pesticide contamination was assessed at the Nebraska Management Systems Evaluation Area. Three 13.4-ha corn (Zea mays L.) fields were studied: a conventional furrow-irrigated field, a surge-irrigated field and a center pivot-irrigat...

homa State University Research Station in Goodwell, OK to measure volatilization losses of ammoniacal N Irrigation of swine effluent is one of the most economical ways to from swine-effluent applied to the land surface by flood dispose of swine manure. The determination of appropriate application rates requires the quantification of volatilization losses of ammoirrigation. Wu et al. (2003) deve...

Population growth and climate change require efficient use of water resources per unit area. In this study, the relationships between irrigation systems, land sizes crop patterns farmers in coastal areas were determined to provide useful information for better agricultural management. A survey study was conducted with 170 using stratified sampling method. The relationship varieties, methods by ...

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...

An experiment was conducted to assess the yield potential and Water Use Efficiency (WUE) of Canola crop grown under sprinkler basin irrigation techniques on a clay loam soil. The designed by Principles Randomized Complete Block Design (RCBD) with two treatments, viz. T1 (sprinkler method) T2 (basin method), replicated four times. Marginal quality water Electrical Conductivity (ECw) 1.83 dS/m pH...
