| Abstract/Description: | In a field experiment, at Sardarkrushinagar, Gujarat during 2006-07 and 2007-08 comprising of three irrigation levels (Irrigation water/Cumulative Pan evaporation Ratio of 0.6, 0.8 and 1.0) in main plot and six levels of weed management practices (weedy check, weed free, Hand Weeding (HW) at 20 and 40 DAS, HW at 20 and IC at 40 DAS, application of Pendimethalin @ 0.75 kg ha-1 (PE) and application of Pendimethalin @ 0.75 kg ha-1 (Pre-emergence) + Inter-culturing at 40 DAS) place in sub plot, it was found that nearly 73 and 27 per cent soil moisture was extracted by root system of fenugreek plant from 0-45 and 45-75 cm soil profile, respectively. In upper soil profile of 0-15 and 15-30 cm relatively higher amount of soil moisture was extracted at 1.0 IW/CPE ratio but in lower soil profile extraction of soil moisture was found more at lower IW/CPE ratio. The highest consumptive use of water (409.89mm) seed yield (1474 kg/ha) and straw (2835but higher water use efficiency (3.94 kg ha-1mm-1), and water expanse efficiency (3.37 kg ha-1 mm-1) was recorded with 0.8 IW/CPE ratios. Higher soil moisture at 0-15,15-30 and 30-45 cm soil profile was extracted in weedy check but from lower soil profile i.e. 45-60 and 60-75 cm weed free treatment followed by pre-emergence application of Pendimethalin @ 0.75 kg ha-1 (PE) + IC at 40 DAS) extracted more soil moisture compared to other treatments.The highest consumptive use of water was recorded in weedy check but WUE and WEE as well as seed, and straw yields were obtained highest in weed free being at par with Pendimethalin @ 0.75 kg per ha +IC at 40 DAS and HW at 20 and 40 DAS. Thus, irrigation at 1.0 IW/CPE ratio along with Pendimethalin @ 0.75 kg ha-1 (PE) + IC at 40 DAS is recommended to get maximum yield |
