Abstract:
A field experiment was conducted at the Agronomy Research Farm, A.N.D. University of Agriculture & Technology, Kumarganj, Faizabad (U.P.) during the Kharif season of 2017-18 with twelve treatments in Randomized Block Design and replicated three times. Total weed population and its dry weight, and 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 attributes like plant height (122.8 cm), number of shoots (441 m-2), leaf area index (3.98), dry matter accumulation (1202 g m-2) and yield attributes like number of effective shoots (428 m-2), length of panicle (23 cm), number of grain panicle-1(186), test weight (23.4 g) were significantly higher with Pretilachlor @ 750 g a.i. ha-1 (PE) fb Bispyribac-Na @ 25 g a.i. ha-1 (POE). and grain yield (54.0 q ha-1) as well as harvest index (44.73).
