Effect of monsoon onset and withdrawal on rice production in Chhattisgarh

Abstract: The variability in monsoonal rainfall has affected agricultural production worldwide. Changes in the onset, withdrawal and distribution of monsoon rainfall have made a risky preposition for rice cultivation. In Chhattisgarh rice cultivation is mainly rain-fed and obviously prone to south-west monsoon variability. The aim of this research was to analyze the probable impact of monsoon onset and withdrawal variability on rice production in different agro-climatic zones of Chhattisgarh during a 29-year period (1989-2017). On the basis of correlation analysis we found that there is significant relationship between withdrawal dates of monsoon and rice production. The r-values was 0.491 (In CPZ), 0.594 (In BPZ) and 0.472 (In NHZ) for the correlation between monsoon withdrawal dates and rice production. The highest value of correlation co-efficient was found for Bastar plateau zone (r = 0.594). These co-efficient are significant at the 1% level of significance in all three agro-climatic zones for withdrawal dates of SWM (south west monsoon) and rice production during 1989-2017. In comparison of average rice production data under different categories of monsoon onset-withdrawal, we found that late withdrawal conditions are favorable for rice production and productivity.
