Daily rainfall and temperature data of recent past 10 years (2001-2010) recorded at the Meteorological Observatory of Sisal Research Station (23.05°N, 84.23°E, and 256.03 m above MSL), Bamra, Sambalpur,-Odisha were analysed to understand the variability and probability of rainfall for sisal based cropping-system in the tribal dominated western Odisha. The mean annual rainfall was 1230.6 mm from 59 rainy-days. The maximum contribution of rainfall was in the kharif season (90.4%). Among standard-meteorological weeks (SMW), 26-29 SMW received the highest rainfall (465.1 mm) which is 38% of-the total rainfall. In a single week the highest rainfall was in the 29th week (140.4 mm). It was computed-that 42.5% of the months were normal months and 32.5% of months faced water deficit situation. Only-four months in a year (June to September) had 100% probability of getting 100 mm rainfall. Expected-monthly rainfall of 250 mm is obtainable only in July and August. Therefore, sowing of rabi crops need-to be completed in early October to get the benefit of residual soil moisture from August rain as well as-to utilize the rain received in October. Mustard can be sown in October utilizing the available moisture; however, it needs assured irrigation during November-December when the probability of getting 50 mm-rainfall is very low (4-10%). In a year, there are two phases of deficit rainfall for sisal and sisal based-cropping system and they are January to May (Phase-I) and October to December (Phase-II). During-June to September, the rainfall is much excess to the ETc demand for sisal and therefore, care is to be-taken to remove the excess water from the sisal field having little natural slope for achieving better-growth and fibre yield.
