ABSTRACT

A field experiment was conducted during summer, 2022 at S.V. Agricultural College Farm, Tirupati. The experiment was laid out in split-plot design and replicated thrice. The treatments consisted of three methods of sowing (3) viz., line sowing (M1), broadcasting (M2) and broadcasting with higher seed rate (M3) assigned to main plots and four weed management practices (4) viz., pre-emergence application of butachlor 1.0 kg ha-1 (W1), pre-emergence application of oxyfluorfen 0.075 kg ha-1 (W2), hand weeding twice at 20 and 40 DAS (W3) and unweeded check (Control) (W4) allotted to sub plots. Among the methods of sowing highest uptake of N, P and K by sesame was with broadcasting higher seed rate. Hand weeding recorded significantly higher N, P and K uptake by sesame crop compared to other three weed management practices. Lower nutrient uptake of N, P and K by crop was with unweeded check.
