Water use efficiency and water production function of Pea cultivars

Sargun Kaur, Mohan Singh

Field experiment was conducted during Rabi season of 2017-18 in randomized block design with three pea cultivars under varying environments with two irrigation levels. Water use efficiency of pea was calculated for both pod and grain yield and was found higher for V2 followed by V1 and V3. Similar trend was observed both for dates of sowing and irrigation levels but higher values were observed for first date of sowing at first irrigation level. A positive and linear relationship was observed between water use and leaf area index (R2 = 84.2), dry matter (R2 = 83.8), pod yield (R2 = 76.8) and grain yield (R2 = 68.5). It is recommended that sowing of pea may be done on or before 1st December for higher yield and PB-89 variety for Rabi season at three days interval of irrigation in mid hills of Himachal Pradesh.
