High water use crops
WebWater use efficiency (WUE) is defined as the amount of carbon assimilated as biomass or grain produced per unit of water used by the crop. One of the primary questions being asked is how plants will respond to a changing climate with changes in temperature, precipitation, and carbon dioxide (CO2) that affect their WUE At the leaf level, increasing CO2 increases … WebAn Introduction to Drip Irrigation.

WebCrop water use is the amount of water given up to the atmosphere by a crop due to evaporation from the soil surface and transpiration through the plant leaves. Crop water use is also called evapotranspiration (ET). Factors that influence ET Daily crop water use changes throughout the growing season due to weather variation and crop development. WebMar 2, 2024 · Results indicate that for the high-water use crop, corn, a payback period of 2.3, 4.9, and 7.6 years for the small, medium, and large investment costs, respectively, is required. As the water use of the crop drops, the payback period rises as it takes longer to realize the gain in system efficiency. For sorghum/wheat, the intermediate-water use ...
WebApproximately 70 percent to 80 percent of crop water use results from plant transpiration. The amount of daily corn water use varies with atmospheric conditions: air temperature, humidity, solar radiation and wind speed. High air temperatures, low humidity, clear skies and high wind speed will result in high ET c demand. WebWater-use efficiency is an important subject in agriculture in semiarid regions, because of the increasing areas under irrigation and the high water requirements of crops. The …
