Abstract
A field experiment was conducted at Agronomy Research Farm, A.N.D. University of Agriculture & Technology, Kumarganj, Faizabad during the Kharif season of 2017-18. The experiment was conducted with Randomized Block Design and replicated three times and comprised with twelve treatments. The herbicides were used individually as well as in combinations viz. Butachlor, Pretilachlor, Bispyribac-Na and Almix. Total weed population and its dry weight, weed index were lowest with Pretilachlor @ 750 g a.i. ha-1 (PE) fb Bispyribac-Na @ 25 g a.i. ha-1 (POE). However, highest weed control efficiency was recorded with Pretilachlor @ 750 g a.i. ha-1 (PE) fb Bispyribac-Na @ 25 g a.i. ha-1 (POE). The growth parameters and yields increased significantly with Pretilachlor @ 750 g a.i. ha-1 (PE) fb Bispyribac-Na @ 25 g a.i. ha-1 (POE) over rest of the treatments. Yield and yield attributes like number of effective shoots m-2, length of panicle (cm), number of grain panicle-1, test weight (g), Grain yield q ha-1), and harvest index were significantly higher with Pretilachlor @ 750 g a.i. ha-1 (PE) fb Bispyribac-Na @ 25 g a.i. ha-1 (POE). Weed free upto 60th DAT gave the maximum gross returns (Rs. 94452 ha-1), however, Net returns (60729.00 Rs. ha-1) and maximum B:C ratio (1.84) recorded with Pretilachlor @ 750 g a.i. ha-1 (PE) fb Bispyribac-Na @ 25 g a.i. ha-1 (POE).
