Online published on 19 April, 2024. Abstract The present study assesses the contribution of area, yield and their interaction of growth in production of sugarcane crop as well as its variability in area, production and productivity. Time series data on area, production and yield of sugarcane for the period 1985-86-2015-16 were collected. The results for decomposition analysis of sugarcane production in phase I were positive in all regions and state as a whole except for Bundelkhand region, interaction effect was found negative -2.39 percent. The area effect was observed highest in Central region with 63.61 percent and the lowest in Eastern region with 33.28 percent. Area effect in entire state was positive with 40.02 percent. Overall yield effect was more than area effect in all the region except central region. In phase II & III contribution of area on production was found to be positive in all regions and the state as a whole except in Western region, where it was found negative. The share of yield was found to be positive in all regions and state as whole. The interaction effect was similarly positive in all regions and the state as a whole. In the course of the phase III, the interaction effect were found negative in Western region with (-0.22) percent while other regions and the state as whole were found to be positive. The variability in area of sugarcane in different regions across all phases was highest in Bundelkhand region in phase III with 30.42 percent and lowest in Western region with 3.22 percent in the same phase. The variability in production in different regions and across different phases varied from 4.82 to 34.00 percent. In the state as whole, variability in production ranged from 4.64 to 11.13 percent. Productivity of sugarcane indicated least variation across all the regions and phases and the state as whole. The highest variation was 17.41 percent recorded in Bundelkhand region and the least was in Eastern region with 4.10 percent. The state as a whole recorded the least variation in phase II estimated to be 4.55 percent and the highest was in phase I with 7.30 percent. In overall the reason for more variability in area, yield and production in Bundelkhand region was due to unfavorable climatic conditions and decisions by the farmers.
