Abstract:

A field experiment was conducted at College of Agriculture, PJTSAU, Hyderabad, during kharif-2016. The experiment was laid out in split plot design with three replications. The treatments consisted of three establishment methods of rice viz., transplanted rice, direct seeded rice and aerobic rice, five levels of weed management practices viz., Farmers method (Hand weeding 20 and 40 DAT/DAS), bispyribac sodium 10% SC 25 g ha-1 as PE fb fenoxaprop-p-ethyl 9.3% EC 62 g ha-1 + 2, 4-D 80% WP 0.5 kg ha-1, penoxsulam+ pendimethalin 25% SE 25 g + 600 g ha-1PE at 4-7 DAS/DAT, pretilachlor 50 % EC 0.75 kg ha-1 as PE fb hand weeding at 20 and 40 DAT/ DAS and unweeded control. The results from present investigation depicts that the direct seeded rice and transplanted rice recorded highest grain yield, straw yield and harvest index. Pretilachlor as PE fb hand weeding twice at 20 and 40 DAS/T, though it was at par with hand weeding twice at 20 and 40 DAS/T produced significantly more grain yield, straw yield and harvest index as compared to other treatments and the maximum gross and net return was recorded under crop raised through direct seeded rice in puddled condition in combination with application of pretilachlor as PE fb HW at 20and 40 DAS/T over rest of the treatments. The benefit: cost ratio was found highest underdirect rice in puddled condition followed by transplanted rice with the application of pendimethalin +penoxsulam as PE at 4-7 DAS/T over rest of the treatments.
