摘要：Medium range weather forecast issued by NCMRWF/IMD was used to prepare weather based agro advisories. Mandal wise rain fall data for four districts of Southern Telangana Zone viz., Ranga Reddy, Medak, Mahabubnagar and Nalgonda were analyzed from 2006-2009 to test the accuracy of the forecast. The analysis revealed that in low rainfall districts like Mahabubnagar and Nalgonda, the correct and usable rain forecast was high (69 to 82%) while in medium rainfall districts i.e., Ranga Reddy and Medak it varied from 61 to 73%. The economic impact assessment of weather based agro advisories in different crops during 2006-09 for the district of Ranga Reddy showed net benefit of Rs. 2,770/-, Rs. 3706, Rs. 3930 and Rs. 4950 per acre by controlling sheath blight, stem borer, leaf folder and hispa in paddy, respectively and Rs. 2700/-, Rs. 820/- and Rs. 4320/- by controlling Helicoverpa in redgram, semilooper in castor and mealy bug in cotton. Thus, for sustainability, equality and stability of production, agro-advisories provides vital component of action research
