Effect of Planting Dates and Weed Management Practices on Grain Yield of Wheat

Competition between weeds and wheat in relation to date of sowing and weed control leve's was studied in a field experiment at Haryana Agricultural University, Hissar. Highest grain yield was recorded when wheat was sown on 15 November. Weed densities were significantly greater in November sown wheat than in December sown wheat. The dry weight of weeds at 60 days after sowing was highest in 15 November sown crop and reduced significantly in late sowings.
