abstract
Experiment for evaluation of IPM package of okra was carried out in 2015-16 and 2016-17 at Allengmora, Jorhat. The results revealed that the population development of sucking pests {Amrasca biguttula biguttula (Ishida) and Bemisia tabaci (Gennadius)} of IPM package and farmer’s practice (Chemical control) were statistically at par. The number of A. biguttula biguttula and B. tabaci population/plant were 0.98 and 0.76 in IPM package whereas they were 1.03 and 0.74 was recorded in farmers’ practice respectively, after third spray. Pertinent to fruit damage, the minimum fruit damage of 8.17% was obtained in chemical control plots as against 9.06% in IPM plot, although they were on par with each other. Regarding yield, maximum yield (102.2q/ha) was registered in IPM package followed by farmer’s practice with 98.57 q/ha and they were statistically significant with each other. Similarly, the highest Cost: Benefit ratio (1: 8.46) was observed in case of IPM plot followed by farmers’ practice (1: 7.98).
