Bagwari, Hari Krishan; Department of Forestry, P.Box-59, HNB Garhwal University, Srinagar Garhwal-246 174, Uttarakhnad, India; Todaria, Nagendra Prasad; Department of Forestry, P.Box-59, HNB Garhwal University, Srinagar Garhwal-246 174, Uttarakhnad, India.
Agro-ecological resource use pattern in a traditional hill agricultural watershed in Garhwal Himalaya was analysed along an altitudinal transect. Thirty one food crops were found, although only 0.5% agriculture land is under irrigation in the area. Fifteen different tree species within agroforestry systems were located and their density varied from 30-90 trees/ha. Grain yield, fodder from agroforest trees and crop residue were observed to be highest between 1200 and 1600 m a.s.l. Also the annual energy input- output ratio per hectare was highest between 1200 and 1600 m a.s.l. (1.46). This higher input- output ratio between 1200-1600 m a.s.l. was attributed to the fact that green fodder, obtained from agroforestry trees, was considered as farm produce. The...
