Abstract

The existence of large yield and technological gaps in different crops is a major problem faced by Indian agriculture. Potato being the most important vegetable of the country, also faces similar problem where actual yields are far below the potential yield. This study was attempted to analyze the yield and technological gap in potato production in Bihar. Data was collected from 90 farmers of Vaishali and Saran districts of Bihar using a structured interview schedule. The results revealed that the overall yield gap of 43.4 per cent existed in potato production in sampled area, which was largely due to the wide scale adoption of a local red skinned potato variety, Bhura aloo. The yield gap was maximum for marginal farmers (48.57%) followed by small farmers. Intensity of adoption was highest for this local variety i.e. Bhura aloo (33.01%) followed by Kufri Sindhuri (27.7%), Kufri Pukhraj (12.64%), Kufri Jyoti (6.83%) and Lal Gulab (5.53%). Large technological gap was observed with respect to the use of recommended dose of NPK fertilizers and pesticides by the farmers. Overall gap in input use per unit area was highest in case of potassium fertilizer (35.4%) followed by nitrogenous fertilizers (27.6%). This yield and technological gaps can be bridged by motivating and supporting farmers to adopt high yielding improved varieties and provision of effective extension services to enable farmers to use recommended level of fertilizers and pesticides.
