Effect of Different Levels of Fertilizer and Residual Effect of INM on Yields and Economic of Broad bean under Black Aromatic Rice-Broad bean Cropping Sequence

Background: Agricultural crop diversification is an important stress relieving option for economic growth of the farming community. Integration of pulses in crop rotation helps in sustainability enhancing overall productivity and profitability of the cropping system. Broad bean (Vicia faba L.) is one of the important pulse crop of Manipur grown in the cool season. Methods: The Present investigation was carried out at Central Agricultural University, Imphal during the kharif and rabi season of 2021-22 and 2022-23. The kharif rice experiment was laid out in randomized block design with 8 treatments as main plot replicated three times. During rabi season each main plot treatment was split into three sub plot treatments with three levels of recommended dose of fertilizers to broad bean resulting in twenty four treatment combinations replicated three times in split plot design. Result: Residual effect of 100% RDF + Azolla + Azospirillum + Neem powder (N5) applied to previous kharif rice crop recorded significantly higher yield attributes, seed and stover yields and economic of broad bean. Among the levels of RDF directly applied to rabi broad bean, application of 100% RDF (F2) resulted in higher values of yield attributes, seed and stover yields and economic of broad bean.
