Effect of different sowing dates on pest incidence in chickpea

Global warming and climate change will have a major bearing on pest incidence and pest associated losses in field crops. Therefore, we studied pest incidence in chickpea across sowing dates to understand the effect of climatic factors on pest incidence on five genotypes of chickpea. The egg laying by the pod borer, Helicoverpa armigera decreased across sowing dates from October to December, with a slight increase in oviposition was observed in the January sown crops. ICC 3137 was most preferred for egg laying ( eggs/5 plants), followed by KAK 2 ( eggs/5 plants). The incidence of H. armigera decreased with a delay in time of sowing ( larvae/5plants in the October sown crop to larvae/5plants in the December sown crop). However, a slight increase was observed in the January sown crop ( larvae/5plants). The highest incidence of H. armigera larvae was recorded on ICC 3137 ( larvae/5plants), and the lowest on ICCV 10 ( larvae/5plants). | Effect of different sowing dates on pest incidence in chickpea
