Description Effect of different sowing dates on chickpea crop and varietal factors against the incidence of legume pod borer Helicoverpa armigera, pod damage and yield were studied at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, Hyderabad, Telangana during the post rainy seasons of 2019-20, and 2020-21. Ten Chickpea genotypes were sown at monthly intervals during first weeks of September, October and November. Each entry was sown in a 6 row plots, with 10 x 30 cm spacing. There were four replications in a split plot design. Among the different sowing regimes tested, November sown crop was found to be optimal and right time for sowing of the chickpea genotype to evade the pod borer coincidence. The borer population fluctuated with the change in dates of sowing. Pod borer population was higher in the early sown crop (September) and with delayed dates of sowing in October and November population decreased. There were significant differences in percent pod damage across genotypes ranging from 10.50 to 40.66 per cent. Minimum pod damage was observed in ICCV 10
and maximum pod damage was observed in ICC 3137. The grain yield ranged from 316.4 kg/ha to 836.1 kg/ha. The highest grain yield was recorded in ICCV 10 and lowest in ICC 3137. Correlation results of pod borer incidence in ICC 3137 showed positive correlation with maximum, minimum temperature and solar radiation, while rainfall and humidity were negatively correlated. Screening the different chickpea
genotypes for resistance or tolerance to H. armigera allowed us in detection of a resistant/tolerant varieties which has shown the minimum level of damage in pods and further for ensuring higher yield with less pod borer damage, November is the optimal time for sowing of Chickpea.
