Abstract:

Yield gap analysis is an increasingly popular concept in agriculture sector.It is always a matter of concern for the research managers, agriculture scientists and development administrators to ensure that the real potential of any crop variety is harvested at the farmers’ field. Further, contributing factors for the yield gap is also very important to manage the higher yields positively. In this study, Yellow mosaic resistant, TBG-104, a new variety of blackgram is considered which showed a higher yield gap between potential yield given by the breeder and the actual yield realized in the farmers’ fields during rabi season. Surprisingly, on an average 1.5 folds more yield is observed in the famers’ fields. A random sample of fifty-two farmers who cultivate TBG-104 was selected from three districts of Southern Zone of Andhra Pradesh and their fields are monitored from sowing to harvesting and data is collected on six factors. Out of six factors, two factors viz., two micronutrient sprays along with pesticide application at recommended level (MN2) and providing supplement irrigation in crucial stages of the crop have been identified as significant contributors in realizing higher yields of the variety. From the regression model it is noticed that the average yield of this variety is 4.9quintals per acre irrespective of other management practices if pest is not infected. By providing supplement irrigation, nearly 1.5 quintals per acre can be protected while 2.7 quintals per acre can be protected with the application of two sprays of micronutrients and usage of pesticides. Hence, this variety can achieve its potentiality in congenial environment with scrupulous crop management i.e. application of nutrients and insect control and providing supplemental irrigation at crucial stages of crop growth.
