Abstract
An experiment conducted during summer 1992 and 1993 with groundnut (Arachis hypogaea L.) on moisture extraction pattern, phasic water use and growth at Chiplima showed that moisture extraction increased with lowering of groundwater table. On an average, crop extracted 18.6 cm water from 60 cm profile under 50 i 10 cm water table depth which increased to 25.2 cm and 26.7 cm at 90 i i 10 and 110 10 cm water table depth respectively. Extraction was the maximum (9.12 cm) at surface layer of 0 15 cm which accounted for 39.9% of the total extraction. It reduced to 7.31 cm (31.6%), 4.53 cm (1 8.7%) and 2.54 cm (9.8%) with increase in profile depth by 15 cm up to 60 cm profile respectively. Groundnut used the maximum water of 3.1 1 cmtday, with maximum growth in terms of crop growth rate (1 0.18 g/m2/day) and net assimilation rate (3.31 g/m2/d) during 56 90 days of its growth. Water use showed significant positive correlation with pod yield at lowest water table depth, r value of 0.994 being the maximum.
