Abstract:
Fruit scarring beetle (Basilepta subcostata Jacoby) is a harmful pest that can cause major damage to banana production. About 40 households cultivated banana in the upland area at NICRA village with the major problem faced by scaring beetle of Banana cultivation. The carried out demonstrated with randomized block design of Banana bunch cover at 10 farmer’s fields of NICRA village in Khanabadi, Kishanganj, Bihar, India during 2021-22 under the supervision of KVK, Kishanganj. Demonstration of banana bunch cover for evaluating the efficacy of a few management strategies against the Banana fruit scarring beetle on Banana cv. Jahaji. The banana bunches that were covered with non-woven polypropylene bags were compared to the farmers' practice of leaving the bunches uncovered. The result of conducted field experiment revealed that among all the treatments application of bunch, cover was found significantly superior in all terms of yield characters. The significant maximum yield (455 q ha^-1) with minimum scarring beetle infestation (1.5%) was recorded in bunch cover Banana. The maximum gross return (Rs 8,64,500 ha^-1), net return (Rs 5,84,500 ha^-1), and benefit-to-cost ratio (2.08) under bunch cover than control. Significant increase in average fruit weight, bunch weight and yield of banana were recorded to the tune of 9.9%, 11.0%, and 10.9% respectively, over control.
