Abstract: The present study has been undertaken to characterise climate and soil of each block of Dhenkanal district of odisha for assessing the suitability of cultivation of winter pulses in rice fallow condition. Daily rainfall and temperature data of 23 years (1995 to 2017) of Dhenkanal district have been collected to estimate amount of rainfall, rainy day, spatial and temporal variability of rainfall, initial and conditional probabilities of dry and wet week and mean monthly, seasonal and weekly temperature using ‘Weather Cock’ software. The district receives 77% of its total annual rainfall of 1367mm through SW monsoon and 155mm in post-monsoon (October-December) with 91% variability. soil texture was analysed by Bouyoucos hydrometer and the soil type were decided by using the textural triangle. Most of the blocks of the district had sandy loam to sandy clay loam textured soil with medium land with 100-150 mm/m available water holding capacity in the rice-fallow area, favours the cultivation of short duration(65-70days) variety of winter pulses like green gram and black gram. Minor irrigation is required for winter pulses in Parajang and Kanakadahad block during 48-49 SMW because there is early withdrawal of moisture and less availability of post-monsoon rainfall.
