In Jharkhand, especially in Chotanagpur region, are most backward areas in Agriculture sector of India. Farmers of this area are by and large resource poor having small and scattered land holdings. Agriculture is the main source of livelihood of rural population. Majority of farmers follow traditional practices of farming which are not very remunerative. The climate of this area is suitable for production of off-season vegetables. Some enterprising farmers have started growing vegetable crops on commercial scale. However, Low germination and survivability of vegetable nurseries in open field due to low temperature during December to January and excessive rain during mid-June to August and wild animal are still major problem. To overcome these problems, a trail was conducted to enhance the germination and survivability of vegetable nurseries using poly tunnel and polyhouse. For trial, four plots of 1× 7m size were prepared by making 6 inch raised bed in open field and 2 beds of same size were prepared in a polyhouse. Two beds of open field were covered with poly tunnels and other two were kept opened. In each bed, seeds of chilli, tomato, broccoli, cauliflower, cabbage and brinjal were sown (each crop in 1×1 m size). All the recommended practices of nursery growing were followed. Result showed early and greater germination per cent age in nurseries grown in poly house and poly tunnel as compared to open fields. The incidences of disease were also less in polyhouse and poly tunnels than in open fields. In polyhouse and poly tunnels, nurseries were ready for transplanting 08-10 days prior to the open field. Based on the result, it can be inferred that use of polyhouse and polytunnel can provide greater germination, survivability, early and healthy nurseries of vegetable crops.
