Updates on following
• Agro-Ecozone selection in the study area
• LDA at new Ag-eco zone level
• Data hunting

Ag-eco zones (AEZ) in the study area• According FAO-GAEZ layer of ‘Reference length of growing period’, total 16 classes fall in the study area
• These 16 classes are aggregated to get 8 classes as follows:
AEZNew zone
0 11,2,3 24,5 36,7 48,9 5
10,11,12 613,14 715,16 8
