Influence of Temperature on Rapeseed-Mustard Yield at Selected Locations in Chhattisgarh State

Mustard is the second most important edible oilseed crop in India after groundnut and accounts for nearly 30 percent of the total oilseeds produced in the country. Weather parameters play major role in determining the crop growth, development and yield because weather strongly influences the physical expression of genetic potential of the crop. The present investigation aimed to find out relationship between maximum and minimum temperature during different stages of mustard crop and yield at three locations of Chhattisgarh state indicated that at Raipur maximum temperature during vegetative stage showed significant negative relation whereas at Jagdalpur significant positive relation was found. Maximum and minimum temperature at any crop growth stage did not have relation with yield at Ambikapur. At the same time, minimum temperature during reproductive stage of crop showed negative relation with mustard yield in all three locations though it was not significant one.
