Pulses contain more protein than any other grains and vegetables. Cultivation of pulses helps to maintain soil fertility through the nitrogen fixation. They are cultivated in many parts and consumed in all parts of the world. The main focus of this paper is to identify and compare the variables, which identify the yield of pulses for Large and Small farmers cultivating Black Gram (BG) and Green Gram (GG) in Tuticorin district, the study area. Multistage stratified random sampling technique has been adopted for the study. The proportionate random sampling technique has been adopted to select 150 each of Black Gram and Green Gram cultivating farmers from these 15 villages. The data relate to the month of November 2012. In the study area,out of 300 sample farmer’s cultivations Black Gram (BG) and Green Gram (GG), 150 sample farms are under the category of Black Gram and remaining 150 sample farms come under Green Gram. It may be concluded from the analysis of Green Gram of pulses farmers, fertilizer was found to be a significant variable in the case of Large farmers. Whereas in the case of Small farmers, capital flows were the most important variable influencing the yield of pulses.
