No doubt the climatic aberrations will severely set back agricultural development in most of the tropical countries particularly India, where an increasing share of the poorest and most vulnerable population resides. Zonal Agricultural Research Station is located at Mandya district of Karnataka lies under agro-climatic zone 6 (Southern dry zone) having longitude of 76° ' E and latitude of 12°' N with 697 meters above mean sea level. Rainfall and temperature data of 28 years (1991-2018) obtained from Agromet observatory, Zonal Agricultural Research Station (ZARS), Mandya, University of Agricultural Sciences, Bengaluru was analysed for variability. The mean annual rainfall of the station is mm distributes Pre-monsoon or summer (March-May) of mm, south-west monsoon (June-September)of , north-east monsoon (OctoberDecember) of and winter season (January-March) of mm. The trend indicated that the maximum contribution was from south west monsoon ( %) and lowest during winter ( %) whereas September was the rainiest month ( mm). The standard deviation (SD) was highest () with Co-efficient of variation (CV) of %, which indicates high variability and dependability on rainfall from S-W monsoon. The mean monthly maximum temperature was °C and mean monthly minimum temperature was °C. | Rainfall and temperature variability analysis of ZARS, Mandya in Karnataka, India
