To Study the Instability and its Causes in Production of Major Pulse Crops in Rajasthan

The study was conducted the growth of area, production and productivity of major pulse crops i.e. gram, lentil, black gram, green gram and pigeon pea crops in Rajasthan. The study was based on secondary data from 1988-89 to 2017-18. Instability in area, production and productivity of selected pulse were worked out for entire period of analysis by Cuddy-Della Valle index and to measure the cause of instability with respect of selected pulse crops i.e. gram, lentil, black gram, green gram and pigeon pea in Rajasthan, acreage response function (log linear function) and yield response function have been used. The study revealed that area and production of selected pulse crops were highly instable in Rajasthan except area under green gram. Subsequently, the productivity of green gram and pigeon pea were also more instable while gram and black gram were found medium instable. In the mean, time productivity of lentil was very less instable. Gram and green gram growers in Rajasthan showed contrary response to lagged area under its competing crop i.e. the decrease in area of competing crop in last year season, thereby that was tendency to increase the area under gram and green gram in Rajasthan. while quite responsive to lagged area under lentil, black gram and pigeon pea crop in Rajasthan. It means the increase in area of lentil, black gram and pigeon pea crops in last year season, there is tendency to increase the area under lentil, black gram and pigeon pea in Rajasthan. The time trend factor showed positive influence on productivity of all selected crops in Rajasthan. Further, seasonal rainfall recorded positive impact on black gram, green gram and pigeon pea crops while on lentil and gram it was negative in Rajasthan.
