Evaluation of IPM Package against Pod borer, Helicoverpa armigera (Hubner) in Chickpea through Front Line demonstration in Chamarajanagara district of Karnataka

Abstract

Chickpea, (Cicer arientinum L) is an important pulse crop is being cultivated in Chamarajanagar district of Karnataka state during rabi season. The main biotic constraint in the production of this crop is pod borer incidence which causes severe losses. To curtail this problem, Front Line Demonstration (FLD) on Integrated Pest management was conducted with farmers participation (80 farmers) during rabiseason of 2015-16 and 2017-18. Results indicated that lowest number of larvae (1.96/m row) and minimum Percent pod damage (6.57%) was recorded in FLD plot as compared to check plot. The Average technology gap, extension gap and technology index were 9.35 q/ha, 1.75 q/ha and 49.20 percent, respectively. FLD plots recorded highest yield (9.65 q/ha) with higher net profit of Rs 23955.50/ha and benefit cost ratio of 2.10 as against farmers practice
