Biomass apprisal of pasture based agroforestry systems in North-Western Himalaya, India

Abstract

Our objective to observed the crop composition of pasture based agroforestry systems and their influence on biomass production in North-Western Himalaya under Sirmaur district of H.P. The study area had four prevailing pasture based agroforestry systems viz. agri-silvi-pasture, silvi-pasture, pastoral-silviculture and pastoral-silvi-horticulture system at three altitudinal zones representing three categories of farmers. The results showed that maximum above ground biomass (23.01 t ha-1) and below ground biomass (6.63 t ha-1) were accumulated by silvi-pasture (SP) system under zone I. Medium farmers category recorded highest biomass production as compare to marginal and small farmers categories due to better management of tress and pastures.
