Abstract
Suitable areas for expansion of khasi mandarin in Meghalaya were identified through land evaluation in GIS environment using information on soil physical, chemical and fertility properties, slope, elevation, rainfall and temperature. The study reveals that 10,457 ha area covering 64.37% of the total study area is suitable for the expansion of Khasi mandarin. Because of steep to very steep slopes, very shallow soil, strongly acidic soils, and low available soil nutrients, 35.63% area is not suitable for Khasi mandarin. It is observed that 64.88% (i.e. 6784.45 ha) area is marginally suitable and 3672.83 ha (35.12%) area is moderately suitable for Khasi mandarin expansion. The maximum area is marginally suitable because of the severe limitation of slope and moderate limitation of soil drainage and soil fertility. Based on constraints of slope (t), drainage (w), soil depth and texture (s) and soil fertility (f); the moderately and marginally suitable areas were classified into 31 and 26 sub classes respectively.
