Résumé partiel
The research work was conducted on “AgroclimaticCharecterizationof Parbhani District” during (2017-18). The historical weather data (1987-2016)collected from Department of Agricultural Meteorology, VNMKV, Parbhani. The rainfall data analysed statistically and different statistical parameters like mean, median, standard deviation, coefficient of variation, coefficient of skewness and kurtosis. Onset, withdrawal of rainy season and length of growing period also determined. Mann-Kendall seasonal decadal and monthly decadaltrend analysis and sen’s slope of rainfall estimated (1987–2016).Initial and conditional probabilities of dry and wet spell for monsoon and post-monsoonrainy season for 20 mm, 40 mm, 60 mm, 80 mm and 100 mm for the 22nd to 48thSMWwere determined, to obtain specific information needed for crop planning and for carrying out agricultural operations. The weekly potential evapotranspiration values were estimated by the Penman-Monteith method and water balance components were determined by Thornthwaite’s book-keeping technique. Average annual rainfall is 949.8 mm with a standard deviation 284.6 mm and coefficient of variation 30 percent. Maximum and minimum rainfall is found to be 1711 mm (1990) and 569.7 mm (2014) respectively. Seasonal mean rainfall for the period June to September is 793.6 mm with standard deviation 285.2 mm. Maximum and minimum seasonal rainfall is found to be 1533.1 mm (1988) and 398.1 mm (2014) respectively.Early onset of rainy season is at 20th week and maximum delay is up to 30th week with mean of 25th week. Early withdrawal of rainy season is at 31stweek, late withdrawal of rainy season in 49th weekwith a mean value of 43rd week
