Impact of Agricultural Extension in Managing Biotic and Abiotic Stress in
Rainfed Areas

India
Various technologies are developed and recommended for management of biotic and abiotic
stress in rainfed areas. Proper and timely adoption of these technologies needs to be accelerated
for harvesting positive economic impacts on farmers’ fields. Among various crop production
factors, management of insect pests and plant diseases are the crucial factors determining the
crop yields. The climate change and weather variabilities created enormous difficulties at
farmers’ level to harvest potential crop yields, mainly in soybean, redgram, gram while to some
extend horticultural crops like papaya, banana and chilli grown in the region. Dryspell of more
than 15 days and heavy rainfall coupled with high humidity and low solar radiation increased
the infestation of stem borer in soybean, fusarium and phytophthora wilt in redgram. Wilting
of gram is a major problem in the predominant soybean-gram cropping system of the region.
Suboptimal micronutrients and low organic carbon content of the soil created unhealthy and
virus infected growth of papaya, banana, and chilli. Extension functionaries need to work
efficiently to disseminate recommended technologies effectively. Hence, it necessitates to
assess the role of an extension agronomist of the Regional Agricultural Extension Education
Institutional and policy innovations for accelerated and enhanced impacts
