Abstract:
A field experiment was conducted during the kharif seasons of 2018 at Agronomical Research Farm of Birsa Agricultural University, Ranchi, Jharkhand, to find out the outcomes of yield attributes, yield and economics of direct seeded rice (Oryza sativa L.) through applied the various integrated weed management practices. Taking all things together, there were twelve treatment combinations comprising of herbicide application and hand weeding practices. The experiment was laid out in randomized block design and replicated thrice. Results revealed that application of Pretilachlor (30% EC) @ 1.00 kg a.i./ha as PE fb Bispyribac sodium (10% SC) @ 0.025 kg a.i. /ha PoE registered higher growth parameter yield attributes viz. number of effective tillers (278/m2 ), number of filled grains/panicle (120/panicle), 1000 grain weight (23.62 g), grain yield (40.52 q/ha) straw yield (60.09 q/ha) and net return (`61864/ha) and was similar to 3 hand weeding at 25, 40 and 55 DAS. Hence, on the basis of one year experiment it may be concluded that application of Pretilachlor (50% EC) @ 1.00 kg a.i. /ha as pre-emergence fb Bispyribac sodium (10% SC) @ 0.025 kg a.i. /ha post-emergence with weed management cost of Rs 4648 /ha is effective in suppressing weed for higher crop growth, grain yield and net return of direct seeded rice under medium land condition of Jharkhand.
