D.K. Mishra, R.S. Tailor, Gopesh Pathak and Alok Deshwal

Abstract

Potato is one of the basic vegetable of mass consumption in India and abroad and become 4th important staple food after rice wheat and maize. Further scope to substantially improve the production and productivity exists especially at Indore region, which identified as Agric Export Zone for potato. Through survey, farmers meeting and field diagnostic visit the yield gap was brought out due to incidence of blight disease in potato field. To overcome the yield gap 50 Front line demonstrations were conducted by K V K, Kasturbagram, Indore during 2002-2007 at 4 development blocks under different locations. Existing farmers practice was taken as a control for comparison and recommended packages involving balance application of nitrogen fertilizer along with Mancozeb 75 % WP as foliar spray at 30,45,and 60 days after planting (DAP). The yield performance of both control and demonstration plot were recorded, and their yield gap, technology gap, extension gap and technology index were analyzed. Potato yield of demonstrated plot recorded 13 to 19 percent higher over farmer practice. On an average technology gap was recorded 63.79 q/ha. Average extension gap was recorded 29.8Q/ha and average technology index was recorded 21.2%. The yield gap analysis emphasize the need to educate the farmers through various extension means for adoption of improved agricultural technologies to revert the trend of wide extension gap
