significance of trend over the years for four agro-climatic zones. The results were cross-checked with those obtained from
Spearman’s rank statistic and deterministic trend analysis. The investigation reveals that in all the zones, annual mean
temperature is significantly increasing. The maximum increase in annual mean temperature is in zone 3 with a tune of
0.3° centigrade in the last century. The results also reveal that the winter months, i.e., November to January are becoming
hotter in all four agro-climatic zones. The monthly mean temperature for zone 1 and 3 is increasing in all the months; on
the other hand it is decreasing in June-September in zone 2 and 4 and increasing in other months.Not Availabl
