Low cost protected structure to enhance vegetable production during rainy season in the foot hills of eastern Himalayan region

Vegetable production in the foothills of the Eastern Himalayan region encounter major challenges during the rainy season (July to October) due to excessive rainfall, waterlogging, and high pest and disease pressure, leading to poor yields and high market prices. The present study examines the economic viability of low-cost protected structures for cultivating vegetables under these adverse conditions. In the year 2023 rainy season (July-October), twelve aerodynamic bamboo structures, covered with UV-stabilized plastic and 50% agro-shade nets, were evaluated to assess four cropping sequence models (CSMs) in the Cooch Behar district of West Bengal, India. The findings revealed that CSM-1, comprising chilli, french bean, and palak, achieved the highest benefit-cost (B:C) ratio of 3.95 with a gross return of ₹ 16,800. Carrot cultivation emerged as the most economically rewarding, generating ₹ 93,600 from an investment of ₹ 29,200 within a 200 m² protected structure. Crops like palak and french bean also showed promising results. The low cost protected structures ensured vegetable availability during the rainy season, optimized agro-input usage, increased cropping intensity, and supported local farmers. This approach has significant potential for enhancing rural livelihoods, fostering entrepreneurship, and creating employment opportunities, especially for youth and women.
