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 کاملCrop Irrigation Scheduling via Simulation-Based Experimentation
Intraseasonal water allocation to a single crop has been studied extensively. Previous studies have emphasized the need to coordinate irrigation scheduling with several factors including economic and physical constraints, amount of soil moisture available at the time of irrigations, growth stage of the plant, interactive effects from previous and/or subsequent irrigation, and the effect, timing...
متن کاملIdentifying Irrigation Strategies for Improved Agricultural Water Productivity in Irrigated Maize Production through Crop Simulation Modelling
Identifying irrigation strategies that improve agricultural water use efficiency (WUE) have a pivotal role to play in sustainable water development. In this study, the AquaCrop model was used to examine the impact of different irrigation scheduling options on yields to identify viable strategies to enhance WUE for irrigated maize. Two scheduling scenarios at water application depths ranging fro...
متن کاملارزیابی مدل MSM جهت پیش‌بینی تبخیر- تعرق ذرت دانه‌ای و مقایسه نتایج آن با مقادیر حاصله از روش‌های پیشنهادی فائو 56
Optimal crop water requirement is needed for precise irrigation scheduling. Prediction of crop water requirements is a basic factor to achieve this goal. In this study, maize potential evapotranspiration (ETp) was prediced by maize simulation model (MSM). Then, it was evaluated and validated using experimental field data obtained in Agricultural Research Station of Shiraz University (Bajghah, F...
