Abstract:
A field trial was conducted to assess the productivity of maize + greengram intercropping systems under different levels of nitrogen doses at Agricultural College Farm, Bapatla, Andhra Pradesh. The experiment was carried out in split plot design with five main treatments (M₁:Sole maize, M₂: Sole mungbean, M₃: Normal planting of maize with one row of mungbean (1:1), M₄: Normal planting with two rows of mungbean (1:2), M₅: Paired row planting of maize with three rows of mungbean (2:3) and four sub plots (S₁: Control, S₂: 50% RDN to maize, S₃: 75% RDN to maize, S₄: 100% RDN to maize) replicated thrice. According to statistical analysis, yield attributes and yield of maize were maximum with paired row planting of maize with three rows of mungbean however on a par with sole maize. The lowest parameters were manifested under normal planting of maize with one row of mungbean. Significantly higher values for yield contributing factors were registered with the supply of 100% RDN to maize followed by 75% RDN to maize. The results concluded that paired row planting accommodating 75% of mungbean population with 100% RDN to maize was found economically profitable.
