The present study was undertaken to determine the sowing window of kharif rice and rabi pulses in different blocks of Dhenkanal district based on the rainfall probability, temperature and length of growing period. The sowing window of kharif rice in Dhenkanal district was found between 23-24 Standard meteorological week (SMW) except Kankadahad, when the conditional probabilities of wet followed by wet (Pww) was >50%. In medium land condition, sowing of pulses (green gram and black gram) is done in 40 SMW in Kankadahad, 41 SMW in Bhuban, Dhenkanal sadar, Hindol, Kamakhyanagar, Parajang and 42 SMW in Odapada by zero till method. In low land condition of Dhenkanal, rabi pulses can be sown in between 44-45 SMW in Dhenkanal sadar and Hindol by zero till method after rice harvest and in between 40-41 SMW in Kanakadahad, 41-42 SMW in Bhuban, Dhenkanalsadar, Kamakhyanagar and 42-43 SMW in Odapada and Parajang with the utilization of residual soil moisture by paira method i.e. 15-20 days before the harvest of rice. The average weekly minimum temperature is 20-24 ºC and chances of occurrence of wet weeks are more than 30% at 20 mm threshold limit of rainfall which is optimum for seeding and germination of pulses in that sowing week.
