Abstract

In on-farm field trials in the 1995 and 1996 rainy seasons in the Sonipat District, Haryana, Cajanus cajan was sown in the first week of May, mid-May or mid-June and pod borer (Helicoverpa armigera) infestation was recorded on 10 randomly selected plants at each sowing. Averaged over the 2 years pod borer damage was 6.5, 25 and 38% for the 3 sowing dates, respectively. Grain yield decreased with delay in sowing from 1.6 t/ha with early sowing to 1.0 t/ha with late sowing in mid-June. It was concluded that sowing C. cajan early is an important management strategy to control pod borer in C. cajan.
