A field experiment was conducted during summer season of 2015 at the Agronomy Main Research Farm, Odisha University of Agriculture and Technology, Bhubaneswar to study the “Performance of summer sesame (Sesamum indicum L.) under various irrigation schedules and weed management practices” .The experiment was laid out in a split-plot design with 3 replications comprising of 3 irrigation schedules in the main plot (IW/CPE =0.8 ,1.0 and 1.2) and 4 weed management practices in the sub –plot (W1 – Weedy check,W2 – Two hand weeding at 21 and 42 DAS,W3 – Pre-emergence application of pendimethalin @ 0.75kg/ha + 1 HW at 42 DAS,W4 – Post-emergence application of quizalofop ethyl @ 0.05kg/ha + 1 HW at 42 DAS). The sesame variety “Prachi” was used as test variety. The crop was sown on 25.02.2015 and harvested on 22.05.2015. The soil of the experimental site was sandy loam in texture, acidic in reaction with medium organic carbon (0.68%), and available N (263.5kg/ha), available P2O5 (10.6 kg /ha) and available K2O (108.6 kg/ha). The moisture content at field capacity and permanent wilting point were 21.6% and 11.8 % respectively. The experimental results revealed that irrigating the sesame crop at IW/CPE ratio of 1.0 recorded the highest seed yield of 835 kg/ha which was at par with IW/CPE ratio of 1.2 (765 kg/ha). Among the weed management practices, pre-emergence application of pendimethalin @ 0.75kg/ha +1 HW at 42 DAS recorded the highest seed yield of 1009 kg/ha followed by two hand weeding at 21 and 42 DAS (833kg/ha). Similar trend was also observed in yield parameters, stalk yield and oil yield. Maximum consumptive use of water by the crop was noticed at IW/CPE ratio of 1.2 (59.8 cm) and in pre-emergence application of pendimethalin @ 0.75kg/ha+1 HW (56.0 cm).But the water use efficiency was found to be maximum (17.78kg/ha cm) at IW/CPE ratio of 0.8 followed by 1.0 and 1.2 respectively and among weed management practices, at pre-emergence application of pendimethalin @ 0.75kg/ha+1 HW (18.02 kg/ha cm).

Keywords: Irrigation scheduling, Weed management practices, Consumptive use and Water use efficiency
