Abstract:

A field experiment entitled “An Analysis on Benefit-Cost Returns of Hybrid Rice under the Influence of Fertilizer and Weed Management Practices” was conducted during the kharif season of 2017 at the Research Farm, TCA, Dholi, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur (BIHAR). The experiment was laid out in a split-plot design with twelve treatments. The results showed that among fertilizer levels, under F3, grain (55.73 q/ha) and straw yield (78.36 q/ha) recorded was significantly superior over F1 level but was found statistically at par with F2 (53.21 q/ha) and (75.19 q/ha), respectively. Maximum net returns were found under F3 (64,512 `/ha) as compared to F2 (61,120 `/ha) and F1 (49,136 `/ha). Still, it was statistically at par with F2 and the B: C ratio was recorded as highest with F3 (1.54), but it was found statistically at par with F2 (1.51), and both the fertilizer levels (F2& F3) showed significantly higher value of B: C ratio than F1 (1.26). In case of different weed management practices, Grain yield (62.35 q/ha) and straw yield (88.00 q/ha)) were significantly higher under W3 than W1 and W4, but it was found at par with W2 (60.23 q/ha), (85.03 q/ha), respectively. Net returns were recorded highest with W2 (76,292 `/ha) which was significantly superior over W3 (70,087 `/ha), W1 (58,591 `/ha) and weedy check (28,054 `/ha) and the highest B: C ratio was found with W2 (1.98) and it was superior over W1 (1.56), W3 (1.44) & W4 (0.77).
