Enhancing grain yield, biomass and nitrogen use efficiency of maize by varying sowing dates and nitrogen rate under rainfed and irrigated conditions |
|
Answer» The prime objective of the study was to investigate the effect of sowing DATE and nitrogen application rates on maize dry matter, grain yield and nitrogen use efficiency under rainfed and irrigated condition. The field experiment was a randomized split plot design with three replicates. Sowing date was taken as the main plot and nitrogen rate was considered as the subplot under both irrigated and rainfed conditions. Two planting dates were considered, NAMELY; timely and LATE sowing scenarios. The nitrogen rates considered were 0 (N0), 75 (N75), 100 (N100) and 125 (N125) kg ha−1 and 0 (N0), 60 (N60), 80 (N80) and 100 (N100) kg ha−1 of urea for irrigated and rainfed maize, respectively. Grain yield and other yield parameters (KERNEL number, and cob number), plant dry matter weight, agronomic efficiency (AEN), partial factor productivity of nitrogen .. |
