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-1 PE 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 higher growth, yield attributes, 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 higher growth, yield attributes, grain yield, straw yield and harvest index as compared to other treatments.
Key words :
Aerobic rice, Direct seeded rice, Transplanted rice, Yield attributes.
