“Among the herbicides sprayed, pre-emergence herbicide atrazine followed by post-emergence herbicide tembotrine had the lowest weed count on 45 DAS (Grasses – 2.90, Sedges – 3.44, BLW’s – 6.68), weed biomass (12.10, 12.55, 6.77 g m2), weed index (0.29%) and highest weed control efficiency (93.28%) and resulted in tallest height (204.12 cm), leaf area index (6.04), dry matter production (8.92 t ha-1), cob length (22.4 cm), grain yield (4.47 t ha-1) and stover production (5.71 t ha-1).”
