ABSTRACT
A field experiment was conducted during rabi season 2012-13 and 2013-14 at Entomology Research Farm, CCS Haryana Agricultural University, Hisar to evaluate different IPM modules and screening of twenty one genotypes of chickpea against Helicoverpa armigera (H.). Among the modules evaluated module M4 with coriander intercropping plus sequential spray with novaluron 1.2 l/ha plus scheduled spray malathion (2ml/l) was found most effective with a lowest mean larval population of 1.38 and 1.21 larvae per 10 plants, lowest pod borer damage of (10.73 per cent and 12.23 per cent), and highest chickpea equivalent yield of (2549 kg/ ha and 2545 kg/ ha) during the year 2013 and 2014 respectively. The module M4 provided the highest benefit cost ratio (BCR) over control during both seasons of study that is 3.74 and 4.13 followed by M2; the least BCR was recorded in M5 during both seasons.
Screening of twenty one genotypes in Randomized block design with three replications revealed that the mean larval population of H. armigera per meter row length (MRL) during crop period ranged between 2.07 larvae per mrl (RSG-931) to 5.8 larvae per mrl (HC-1) during (2012-13) and it was 2.73 larvae per mrl (RSG-931) to 5.71 larvae per mrl (HC-1) during (2013-14). Mean per cent pod damage at harvest ranged between 8.18 (HK-2) to 22.76 (H08-61) during (2012-13), 9.56 (H04-28) to 23.64 (H08-61) during (2013-14). The pod yield ranged from 4.79 q/ha (H08-61) to 12.47 q/ha (RSG-931) during 2012-13, during (2013-14) the pod yield was ranged from 4.74q/ha (H08-61) to 11.74 q/ha (RSG-931).The pest susceptible rating ranged from 3 to 6 during both seasons.
