Irrigation Scheduling for Maize and Indian-mustard based on Daily Crop Water Requirement in a Semi- Arid Region
Maize and Indian mustard are significant crops in semi-arid climate zones of India. Improved water management requires precise scheduling of irrigation, which in turn requires an accurate computation of daily crop evapotranspiration (ETc). Daily crop evapotranspiration comes as a product of reference evapotranspiration (ET0) and the growth stage specific crop coefficients modified for daily var...
متن کاملDeficit irrigation for reducing agricultural water use.
At present and more so in the future, irrigated agriculture will take place under water scarcity. Insufficient water supply for irrigation will be the norm rather than the exception, and irrigation management will shift from emphasizing production per unit area towards maximizing the production per unit of water consumed, the water productivity. To cope with scarce supplies, deficit irrigation,...
متن کاملModification of transient state analytical model under different saline groundwater depths, irrigation water salinities and deficit irrigation for quinoa
Salinization of soil is primarily caused by capillary rise from saline shallow groundwater orapplication of saline irrigation water. In this investigation, the transient state analytical modelwas modified to predict water uptake from saline shallow groundwater, actual cropevapotranspiration, soil water content, dry matter, seed yield and soil salinity under differentsaline groundwater depths, i...
متن کاملeffects of deficit irrigation on yield and yield components of maize and determining of water productivity in nekuabad irrigation network
to illustrate the impact of various levels of deficit irrigation on yield and yield components of maize cultivars, a study was conducted based on randomized complete blocks as a split plot design with 3 replicates and two treatments for three crop seasons. four levels of deficit irrigation including: conventional, 100, 80, and 60% of water level use were considered as main plots and two varieti...
