Abstract:
Agriculture is influenced by temperature variability in a number of ways, including its heat wave, increase in maximum temperature, cold wave and frost etc To analyse, the present climate status, the long term weather data (1980-2020) viz, mean maximum temperature of different districts of Chhattisgarh were collected from the Department of Agrometeorology, College of Agriculture, Raipur. Analysed in excel tabular analysis. The highest increase in annual maximum temperature was observed at 33.29 ℃ in the year 2009, whereas the lowest maximum temperature was observed at 31.42 ℃ in the year 1990. it is also observed that the maximum temperature is increasing significantly at the rate of 0.0135 ℃ per year. The highest increase in annual temperature was observed in Sukma, Kondagaon, and Narayanpur observed for 0.0139 ℃ increase per year. The state average summer mean maximum temperature was observed as 37.42 ℃ over 40 years with 2.18 percent of the variability. The maximum temperature of June is more unstable, followed by March, April, and May. The state average winter mean maximum temperature was observed as 28.68 ℃ over 40 years with 1.95 percent of the variability. The state winter maximum temperature of January is more unstable, followed by December, October, and November. Plain and cultivation of high temperature-demanding crops is appropriate in Bastar Plateau districts, while cultivation of low temperature-demanding crops is more advantageous for farmers in Northern Hills districts.
