Abstract


A field experiment was conducted at RARS, Bijapur of UAS, Dharwad, Karnataka during 2001-02 to assess the influence of chickpea based Agri-silviculture system on soil nutrients and its economic feasibility. The experiment consisted of seven tree spp. Chickpea was sown and maintained as per the recommended practices. The soil was analysed for chemical properties and yield parameters were recorded at harvest. In Agroforestry systems, over a period of time on the soil fertility status. It was increased due to the leaf litter fall and reduction of pH, EC. The treatment of Leucaena Leucaena leucocephala was recorded highest N 158.20 kg/ha, P2O5 16.45 kg/ha K2O 530.7 kg/ha and organic carbon 6.15 g/ha whereas lowest was seen in C. siamea. The chickpea grain yield was highest (950 kg/ha)in sole crop (no trees) and lowest in (513 kg/ha) in Acacia nilotica. Among the tree spp. H. binata recorded highest yield of chickpea (873 kg/ha) which was 92 per cent of sole crop. The net returns were highest in H. binata + Chickpea (Rs. 10,212/ha) and minimum was found in C. siamea + Chickpea (Rs. 4527/ha). Thus, H. binata+chickpea agrisilvicultural system is economically feasible.
