Indian economy is an emerging economy, but it is still an agricultural economy because here, most people earn their livelihood from agriculture. The present study for temporal changes in Rajasthan time series, data on area, production and yield per hectare of food grain and oilseeds crops were collected from 1976-77 to 2018-19. The area under wheat, bajra, maize, urad, moong, rapeseed & mustard and soybean was increased by 67.12 %, 2.68 %, 12.91 %, 333.19 %, 1009.40 %, 729.27 % and 3089.07 %, respectively from 1976-79 to 2016-2019. The area under barley, gram, sesamum, was reduced by -47.01%, -12.41 % and -34.59 % which was shifted towards pulses, and oilseeds and cereal crops like moong, urad, soybean, rapeseed & mustard and wheat. During the study period, production of wheat, barley, bajra, maize, gram, urad, moong, rapeseed & mustard, sesamum and soybean was increased by 360.62 %, 39.42 %, 256.42 %, 166.65 %, 11.23%, 565.41 %, 1776.25 %, 2487.47 %, 32.73 %, and 6019.05 %, respectively. The
yield of wheat, barley, bajra, maize, gram, urad, moong, rapeseed & mustard, sesamum and soybean was increased by 174.96 %, 161.39 % 242.27 %, 138.83 %. 26.78 %, 55.40 %, 69.25 %, 214.14 %, 103.16 % and 90.61 %, respectively period of study. The area under barley, gram and sesamum reduced during the study period. Therefore, technological support through varietal improvement and extension support is required. Enhance minimum support prices of cereals, oil seeds and pulses crops farmers motivated
for cultivation of these crops.
