- Abstract
A field experiment was conducted in the farmer's field, Semmangudi village, Sirgali taluk, Nagapattinam district, Tamil Nadu during summer, 2018 to study the productivity and profitability enhancement of hybrid pearl millet (Pennisetumglaucum L. R. Br.) through weed management. The experiment was laid out in Randomized Block Design (RBD) with three replications. The treatments of unweeded control (T1), hand weeding twice at 15 and 30 DAS (T2), pre-emergence application of atrazine (750g ha-1) on 3 DAS (T3), pre-emergence application of pretilachlor (450g ha-1) on 3 DAS (T4), early post-emergence application of fenoxaprop-p-ethyl (56.25 g ha-1) on 10 DAS (T5), early post emergence application of metsulfuron methyl + chlorimuron ethyl (4 g ha-1) on 10 DAS (T6), pre-emergence application of atrazine (750gha-1) on 3DAS + one hand weeding on 30 DAS (T7), pre-emergence application of pretilachlor (450 g ha-1) on 3DAS + one hand weeding on 30 DAS (T8), early post-emergence application of fenoxaprop-p-ethyl (56.25g ha-1) on 10 DAS + one hand weeding on 30 DAS (T9), early postemergence application of metsulfuron methyl + chlorimuron ethyl (4g ha-1) on 10DAS + one hand weeding on 30 DAS (T10). Among the different weed management practices in hybrid pearl millet, pre-emergence application of pretilachlor (450g ha-1) on 3DAS + one hand weeding on 30 DAS (T8) significantly recorded the highest nutrient uptake by crop and growth and yield parameters such as plant height, LAI, DMP, number of tillers plant-1, ear head length, ear head girth, number of grains ear head-1 and lowest nutrient removal by weeds. Hence from the results, it is revealed that pre-emergence application of pretilachlor (450g ha-1) on 3DAS followed by one hand weeding on 30 DAS (T8) was an efficient and economically feasible practice to manage the weeds in hybrid pearl millet with better returns.
