Effect of deficit irrigation on crop growth, yield and quality of onion in subsurface drip irrigation
Indiahas the largest area under onion (Allium cepa) crop but its average productivity (14.21 t ha-1) is considerably lower than the world’s average of 19.4 t ha-1. Besides low productivity, irrigation efficiencies are also very low i.e. 30-35% in India. Managing onion crop with less than adequate irrigation water availability is a challenge in several parts of the country. Options of i) deficit...
متن کاملEvaluating the Efficiency of Clay Reservoirs for the use of Unconventional Waters in Subsurface Irrigation
Introduction: As Iran faces limited water resources, it should take the use of unconventional waters into account in its drought management. In many countries, including Iran, conventional water is relatively scarce. However, should water, soil, and plants be appropriately managed, there would be significant saline water sources for irrigation purposes. Together with reducing salinity and refin...
متن کاملEffect of irrigation amounts applied with subsurface drip irrigation on corn evapotranspiration, yield, water use efficiency, and dry matter production in a semiarid climate
Quantifying the local crop response to irrigation is important for establishing adequate irrigation management strategies. This study evaluated the effect of irrigation applied with subsurface drip irrigation on field corn (Zea mays L.) evapotranspiration (ETc), yield, water use efficiencies (WUE = yield/ETc, and IWUE = yield/irrigation), and dry matter production in the semiarid climate of wes...
متن کاملAdvantages and Disadvantages of Subsurface Drip Irrigation
The advantages and disadvantages of subsurface drip irrigation (SDI) as compared to alternative irrigation systems are conceptually discussed. Each category (advantages and disadvantages) is subdivided into three groups: 1) Water and soil issues; 2) Cropping and cultural practices, and 3) System infrastructure issues. The adaptation and adoption of SDI systems into diverse cropping systems, geo...
متن کاملAdvantages and Disadvantages of Subsurface Drip Irrigation
Subsurface drip irrigation (SDI) applies water directly to the crop root zone using buried polyethy lene tubing, also known as a dripline, dripperline, or drip tape (Figure 1). Driplines come in varying diam eters and thicknesses in order to maintain acceptable irrigation uniformity for different field lengths. Smaller diameter driplines are used when short lateral lengths are required. As la...
