Performance Analysis of Sorghum in Tamil Nadu

Sorghum (Jowar) is an important crop for poor, small and marginal farmers in Tamil Nadu. In the production of sorghum, Tamil Nadu ranked 4th in India. The purpose of the study is to observe the trend and instabilities in the area, production and yield of sorghum in Tamil Nadu from 1991-92 to 2021–22 using the simple regression model, the coefficient of variation, the Cuddy Della Valle index and decomposition analysis. The growth analysis specifies that sorghum area has decreased with a compound growth rate of 0.47 percent, production of sorghum has reduced from 552.6 thousand tonnes to 427.21 thousand tonnes and the growth analysis of yield shows that it has increased by 0.37 percent in the overall study period. The results expose that instability in the area in terms of CDVI value was 6.26 percent, the instability in production was 34.67 percent, and instability in yield exposes the highest variability of 22.98 percent in the entire period. Instability in the area in terms of coefficient of variation values was 23.67 percent, in production coefficient of variation was 34.33 percent, and in yield it was 23.09 percent instability in the entire period. It can be resolved that production of sorghum was more unstable in association with yield and area in Tamil Nadu during all sub-periods and the entire period. The entire period analysis tells that the area and yield effects were 140.48 and 98.33, respectively, while the interaction effect was -31.34. According to the study, both area and yield were increased sorghum production of the state.
