The present investigation was conducted to analyse the factors responsible for yield gap in soybean in Baran district of Rajasthan. Baran is a major soybean producing district in the state but the productivity of soybean in average farmer’s farm is well below its potential yield. Changes in cropping pattern and crop groups were also analyzed for the period 2001 to 2015. Kendall`s coefficients of concordance was estimated for analyzing the change in cropping pattern and tested for their significance. The coefficient of concordance for Baran district was estimated as 0.70 which was significant at 1 per cent level of significance. Share of cash crops has increased overtime and it became almost half of total gross cropped area, while share of pulse crop group decreased.

For analyzing the yield gaps in soybean and its decomposition, primary data for the year 2014-15 and 2015-16 were used. Potential yield of whey was taken from (KVK) KrishiVigyan Kendra of that district. Three types of yield gaps were worked out for soybean. Where Gap-I denotes technology gap, Gap- II denotes package of practice gap and Gap- III gives resource constraint gap. Decomposition of yield gap was done with the Bisaliah (1977) model of decomposition. The gap between average farmer’s farm and best farmer’s farm was 65.37 percent. During decomposition of various factors level of input use contributed 180.68 per cent turn out to be the major contributor.
