Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
viz., 3757, 3792, and 3716 kg ha -1 soybean SEY, respectively. Interaction effect between the
land configuration practices and cropping sequences, no significant effect was observed on
yield attributes, yield, and economics of either cotton or soybean intercropped with pigeonpea
or soybean-based various crop sequences.
Conclusion
BBF method of cultivation is found to be superior to ridge and furrow method or traditional
flatbed method of soybean cultivation. In Dryland agriculture or rainfed situations, based on
soil moisture regimes, cultivation of intercrops or sequence crops are always better than sole
crops by making use of proper land configuration practices like BBF or ridge & furrow
methods.
