The regression analysis indicates that the area under rapeseed-mustard is positively and significantly increasing in Raipur (R = 0.70**), Durg (R = 0.65**), Rajnandgaon (R = 0.71**) and Surguja(R = 49*) districts because it is an irrigated crop, so increase irrigation facilities in these districts, have led to increase in cultivation of rapeseed-mustard. However, the increasing trend in rapeseed-mustard area in Bastar, Raigarh districts is not significant. The area of rapeseed-mustard is sharply decreasing in Bilaspur (1253 ha/year), which poses serious threat for the production of rapeseed-mustard in Bilaspur district. The area in Raigarh under rapeseed-mustard cultivation showed no change during study period except in last two years in which, area has increased many fold. The production under rapeseed-mustard showed positive and significant increase in Raipur (R = 0.71**), Durg (R = 0.63**) Rajnandgaon (R = 0.73**), Raigarh (R = 0.56**) and Surguja (R = 0.71**) districts, however the increase of production in Bastar district is non-significant (R = 0.26). The increasing trend in production can be attributed to increased area and productivity of rapeseed-mustard in these districts. The production in Bilaspur (R = 0.64**) district is decreasing due to declining area of cultivation under rapeseed-mustard. The productivity of rapeseed-mustard showed increasing trend over the study period in the entire state due to technology impact, intensive cultivation by progressive farmer, integrated pest disease management and use of high yielding varieties. Whereas, the impact these practices is not much sound in Raipur district (R = 0.14).
