Casuarina equisetifoliais the most widely planted species in India having multiple utility and suitability in agrarian ecosystem. Present study was carried out fifteen –year –old Casuarina equisetifolia (Jhau) trees, planted at10 x 3m distance with wheat variety NW-1067 and paddy variety Sarjoo-52 was taken in RBD experimental design with four replications in five treatments along with using cultivated in Agri-silviculture system and open area. Findings revealed that maximum growth of C. equisetifolia (tree height 14.75m and dbh 28.10 cm etc at end of experiment) was measured in T2 (NPK 120:60:40 kg ha-1). The signifcantly highe grain yield(27.6 q ha-1 and 29.20 q ha-1) of wheat variety NW-1067 has been achieved due to T2 (NPK 160:60:40 kg ha-1) treatment in agri-silviculture system and open area respectively, whereas signifcantly higher grain yield (38.40 q ha-1 and 40.70 q ha-1) of paddy variety Sarjoo-52 has been achieved due to T2 (NPK 160:60:40 kg ha-1) treatment in agri-silviculture system and open area respectively. It may be concluded that additionalincome of the farmers can be generated by successful utilization of vacant land under C. equisetifolia based agri-silviculture system as inter crops of wheat computed with enhancing fertility status of soil.
