Abstract

Daily rainfall data for 47 years (1960-2006) of Karimganj, Assam were analysed. The overall mean annual rainfall was 4073.5 mm, which was distributed as 2613.6 mm, 1134.8 mm and 330.3 mm in kharif (June to September), summer (March to May) and rabi (October to February) seasons, respectively. The probability of 60 and 100 mm rainfall per week exceeds 70 per cent values between 18th to 37th and 22nd to 30th week, respectively. In flood free upland and medium land areas transplanting of ahu rice is suggested to complete within first week of April and the second crop of rice (sali) could be transplanted from 31st week onwards. In upland area, sowing of toria/potato/vegetables may be started from 43rd week onwards. In areas where the second crop of rice is not possible due to flood, the ahu rice should be followed by potato/toria/pulses/vegetables etc from 43rd week onwards.
