Redgram is an important pulse crop in India. New cropping technology increases the yield in the production of redgram. In order to examine variation in yield due to introduction of new technology, a study was carried out in Bidar district of North Karnataka during the year 2011-12. It was found that cost of cultivation under transplanted redgram (` 37139/ha) was higher than that of dibbled (` 34007/ha) method. Although the farmers of transplanted method spent more compared to dibbled method, the net return obtained in transplanted method was much higher (` 67523/ha) as against dibbled (` 58052/ha) method. The Cobb-Douglas production function was used to estimate the contribution of inputs towards the return, the output elasticity of seeds, human labour and irrigation in both methods like transplanted (0.25 , 0.80 and 0.05) and dibbled method (0.11, 0.44 and 0.18) were positive and significant. Thus the use of seeds, human labour and irrigation will positively and significantly influence the gross returns in redgram production under both transplanted and dibbled methods. The ratios of MVP to MFC were greater than one for all the factors used in both the methods except manures and fertilizers in transplanted method and manures and fertilizers and plant protection chemicals in dibbled method. The decomposition analysis indicated that the difference in total output between transplanted and dibbled method of redgram cultivation was 16.04 per cent that is in transplanted method 16.40 per cent higher than that of dibbled method. The transplanting technology alone has contributed to the extent of 19.08 per cent while the contribution of increased use of inputs was found to be negative.
