Abstract
A field experiment was carried out to estimate biomass production, carbon stock, carbon sequestration and economic performance of Melia dubia under agri-silviculture system. This experiment was laid out in a Split design and replicated thrice, treatments comprised of two main plots (Clones) M I MTP-I M II MTP-II and seven subplots(Intercrops) T 1 Finger millet , T 2 Foxtail millet, T 3 Pearl millet, T 4 Greengram, T 5 Blackgram, T 6 Cowpea, T 7 Only trees. Sole crop without trees are maintained. Results showed that MTP-I clone recorded higher volume, biomass production, carbon stock, carbon dioxide sequestration in agri-silviculture system when compared to MTP-II and sole crop. In terms of income wise MTP-I recorded higher gross returns, net returns and B:C ratio than MTP-II. Incase of intercrops, blackgram registered higher net returns and B:C ratio than other intercrops.
