OAR@ICRISATEffect of varied weather parameters and different sowing dates on the incidence of insect pest in chickpeaJJabaauthorTPavaniauthorSVashisthauthorS PMishraauthorH CSharmaauthorIt is important to identify genotypes with resistance varied sowing windows. Therefore, evaluated a five diverse genotypes for resistance to H. armigera for three years over four sowing window. More number of eggs were observed in 2012 than in 2013 and 2014. Highest numbers of eggs were recorded in the crop sown in October in cumulative three seasons. Among the genotypes tested, ICC 3137 had the highest number of H. armigera eggs (11.6) across the seasons. The lowest number of H. armigera eggs was observed on JG 11 (6.3) in 2012, on ICCV 10 (3.6) in 2013. The H. armigera larvae were highest in October sown crop (80.7) and lowest in the January sown crop (21.1) in 2014-15. The larval incidence decreased from October to December but increased in the January. Greater numbers of cocoons were recorded in the December sown crop (3.4) in 2012-13.However highest number of cocoons were recorded on ICC 3137 (2.5) and lowest on KAK 2 (1.6). The maximum temperature and minimum temperature shows a significant negative and positive correlation with H. armigera larvae population for October and November sown crop. Multiple regression analysis of the H. armigera, S. exigua eggs and larval population showed a significant interaction with weather parameters during all cropping seasons. The coefficient of multiple determinations (R2) was varied per cent during across different seasons for H. armigera, S. exigua populationPest ManagementChickpeaPlant Physiology2019-11Conference or Workshop Item
