Linear disease prediction model in groundnut rust epidemics.

摘要

Field trials were conducted in Dapoli, Konkan, Maharashtra, India, to study development of rust (Puccinia arachidis) of groundnut cv. Konkan Tapora in relation to weather parameters during the 2003 kharif and 2003-04 rabi, seasons. The main object was to develop environment-based linear prediction model to predict rust before the actual appearance using the stepwise multiple regression analysis. Maximum temperature, minimum temperature, maximum relative humidity, wind speed, sunshine hours, rainfall and crop age were had high correlation with the rust disease during 2003 kharif, while during 2003-04 rabi, maximum temperature, minimum temperature, relative humidity, wind speed, rainfall, evaporation and crop age were the highly correlating factors for rust development in groundnut..
