Seed yield losses in sunnhemp (Crotalaria juncea Linn.) due to pod borer complex

Field experiments to estimate the loss of seed yield due to attack of pod borers in two varieties (K-I2 yellow and K-I2 black) of sunnhemp were conducted for three years. Pooled per cent loss of seed yield was estimated to be 15.05 for K-12 yellow and 21.31 for K-12 black variety. Pooled per cent incidence of pods due to pod borer complex for K-I2 yellow variety of treated plots was 1.69 and that of control was 21.63 while for K-12 black variety it was 9.91 for treated plots and 24.10 for control plots. Pooled average seed yield for K-12 yellow variety of treated plots was 5.51 and that of control was 4.68 Q/ha while for K-12 black variety for treated plots was 3.86 and -that of control plots was 3.04 Q/ha. Rainfall and temperature were the responsible factors for variation in pod borer incidence. All the treatments were found to be significant.
