Abstract:

A farmer’s participatory trail was conducted during Kharif season of 2014 and 2015 on farmers’ field at Kumar village (Sikandra) of Jamui district (Bihar) under CSISA project. The experiment was laid out in the factorial randomized block design using three way ANOVA table. The experiment consisted of four tillage practices viz. T1-Stale bed direct seeded rice, T2-ZT direct seeded rice, T3-Mechanical transplanted rice, T4-Conventional puddle transplanted rice and six weed management practices viz. W1-Weedy check (control), W2-Weed free, W3-Pyrazosulfuron at 20 g ha-1 as pre emergence, W4-Oxadarzil at 18 g ai ha-1 as pre emergence, W5-Pyrazosulfuron at 20 g ha-1 as pre emergence fb bispyribac sodium at 25 g ai ha-1 at 22 DAS and W6- Oxadarzil at 18 g ai ha-1 as pre emergence fb bispyribac sodium at 25 g ai ha-1 at 22 DAS. Treatment T3 mechanically transplanted rice recorded highest plant height (94.20 cm), number of effective tillers (250.64), dry matter m-2 (1369.7 g), length of panicle (24.12 cm), weight of panicle (2.72 g), no. of grains (115.47), test weight (25.62 g) grain and straw yield 3778 kg and 6105 kg ha-1 respectively. Lowest Weed density (26.34 and 6.02) and weed dry weight (3.03 and 6.04 g) were recorded with stale bed direct seeded rice at 30 and 60 DAS. Under weed management practices lowest weed density (9.34 and 3.03) and weed dry weight (0.88 and 2.82 g) at 30 and 60 DAS. Maximum Grain (3847 kg ha-1) and Straw yield (6184 kg ha-1) was recorded under treatment W5 Pyrazosulfuron at 0.20 kg ha-1 as pre emergence fb bispyribac sodium at 0.20 kg ai ha-1 at 22 DAS. The maximum net return was obtained with treatment W5 (Rs. 28,631) and B: C ratio of 2.05.
