Abstract:
Sesame, ‘the queen of oilseeds’ occupies a major share of oilseed production in India. Slow growth during initial growth stages contributes to heavy weed infestation, leading to low yield and quality in sesame. The investigation was conducted at ‘College of Agriculture, Raichur’ to analyze different pre and post-emergence herbicides and inter-cultivation for weed management practices in Sesame (Sesamum indicum L.). The field experiment consisted of 8 different weed management treatments. Randomized Block Design (RBD) was used as the design with three replications. Preemergence application of alachlor 50 EC @ 0.75 kg ha^-1 along with hand weeding at 30 DAS and inter-cultivation at 45 DAS gave significantly lower dry weight of weeds at 20, 40, 60 DAS and at harvest (0.73, 0.63, 0.85 and 1.80 g/m², respectively) followed by Post-emergence application of Quizalofop 5 EC @ 40 g ha^-1 at 20 DAS along with Inter-Cultivation at 45 DAS. Concerning dry matter production and chlorophyll content, Preemergence application of alachlor 50 EC @ 0.75 kg ha^-1 along with hand-weeding at 30 DAS and inter-cultivation at 45 DAS resulted in significantly higher values when compared to other treatments. Among the treatments, preemergence application of alachlor 50EC produced the highest yield of seeds (480 kg ha^-1).
