AGRO ECOLOGICAL ZONATION OF FUSARIUM MANGIFERAE FOR ANDHRA PRADESH AND UTTAR PRADESH STATES OF INDIA

摘要

The study of Agro ecological zonation of Fusarium mangiferae in two states namely Andhra Pradesh (AP) and Uttar Pradesh (UP) of India were taken, in which randomly selected locations numbering 42 and 112 were identified respectively. For these locations climatic data pertaining to maximum and minimum temperature, RH, wind speed and evapotranspiration were collected for a period of 30 years (1972 - 2002).The data was used to generate weather surface on the vector map of AP and UP. The vector maps were prepared using the GIS. The Fusarium favourable areas are mapped by using 'threshold values' of weather parameters and geostatistical techniques. The result so obtained after layering, the favourable conditions for occurrence of mango malformation were found only in certain pockets of north western AP and entire state of UP. GIS tool was found to be very useful for prediction of spatial distribution of MM at regional scale.
