Pest management in pulses under rice-wheat crop diversification uri icon


  • Concerted research and developmental efforts supported by government policies brought aparadigm shift in favour of rice-wheat cropping system (RWCS) in the last three decades inthe Indian Indo-Gangetic plain (IGP). This shift has relegated traditional pulses such aschickpea and lentil to less favourable environments. There are increasing concerns that highinput rice-wheat cropping rotation in the IGP is reaching productivity limit, and further thatthe edaphic resource base is under threat due to various degradation process. As thesustainability of such input systems is increasingly under question throughout the IGP, it hasbecome necessary to readdress, and further rehabilitate pulses for the sustainability of theRWCS. However, the evidences revealed that pulses are prone to several abiotic, biotic andsocio economic constraints in augmenting their production. Among biotic constraints importantones are diseases and insect pests. Together these two biotic constraints can cause a totalloss to a pulse crop. Enormous opportunities exist for production of pulses with integratedpest management (IPM) in the RWCS, such as short duration mungbean as a summer crop,pigeonpea in rotation with rice, and chickpea and lentil in rotation with wheat. It is, therefore,critical to delineate the promising niches in the RWCS for each pulse crop and introduceappropriate IPM technology with available components of pest management. Also, there is aneed to create a favourable environment for pulse culti vanon and IPM promotion throughpolicy support. This paper critically examines the niches for rehabilitation of pulses andpromotion of IPM for sustainability of the RWCS
