A Statistical Model for Ascertaining the Influence and Reliability of Weather Parameters on Incidence of Blossom Blight in Mango (Mangifera indica L.)

A statistical model was developed to study the influence and reliability of weatlier parameters on incidence of blossom blight in Mango (Mangifera indica) and subsequently to predict their incidence. Results showed that preceding week's weather variables viz., maximum and minimum temperature, e...
