The domestic and foreign research in the field of rice cultivation carried out over past 10-15 years has identified four main promising technologies that can reduce cost produced: 1 - intermittent flooding; 2 periodic moistening without creating a layer water; 3 sprinkling, including surface irrigation; 4 drip irrigation. Drip irrigation is most priority area research, since it significantly ra...

in arid, semiarid, and mediterranean climates, particularly in west asia and north africa, farmers face limited water resources and must develop irrigation management methods to increase crop production while reducing water use. this study examined methods to reduce irrigation water loss and increase maize water productivity at safiabad agricultural research center in dezful, iran in 2007 and 2...

this study evaluates the effect of irrigation method on the water use efficiency and yield of onions at the zahak agricultural research station in sistan province. the testing was conducted using a split plot arrangement and a randomized complete block design with three replications during the 2005-2006 crop seasons. irrigation methods were basin and drip tape irrigation and the irrigation leve...

ABSTRACT DMulching contributes to the maintenance of soil moisture at reasonable levels for crop growth. It influences water demand and irrigation time. The aim this study was estimate evapotranspiration root uptake by ‘BRS Princesa’ banana cultivar through a simple approach using some components balance within zone in bare mulched irrigated drip micro sprinkler systems. experimental design com...

Nitrogen compounds added to the soil may convert nitrate and cause contamination. The distribution uniformity of in surface vs. subsurface drip irrigation systems were compared a physical model consisting transparent glass box (1.20 x 0.5 1 m) sandy loam soil, considering emitter installation depths 0 30 cm, discharge rates Q1 = 2, Q2 4, Q3 8 L/h, fertilizer levels S1 125, S2 250, S3 375 mg/L. ...

Long-term use of drip irrigation technology may lead to root degradation and affect shoot growth and yield. A field experiment was conducted to investigate aboveand belowground growth responses to drip irrigation under mulch film (DI) in comparison to flood irrigation under mulch film (FI) in cotton. The monolith method was used to harvest roots at seven timepoints in the growth periods, and th...

High air temperatures during the crop growing season can reduce harvestable yields in major agronomic crops worldwide. Repeated and prolonged high night air temperature stress may compromise plant growth and yield. Crop varieties with improved heat tolerance traits as well as crop management strategies at the farm scale are thus needed for climate change mitigation. Crop yield is especially sen...

Israel is a small country with a total land area of 21,000 km, from which 20% is arable land. More than half of Israel has an arid to semi-arid climate. Approximately half of the cultivated area (200,000 hectares) has to be irrigated due to lack of rainfall and other water resources. Approximately 80% of the irrigated land in Israel uses the fertigation method, combining the application of wate...
