moisture loss. These results are in agreement with those reported by Singh (2011). IV. C onclusion and R ecommendation In agro-forestry system of guava + groundnut cv. Dh-86 and cv. ICGV-93468 + soil application of neem leaves powder @ 100 kg/ha and spraying of neem oil on guava plantation @ 2.5 lit/ha gave highest fruits yield of guava and pods yield of groundnut during summer season, therefore, farm families of guava and summer groundnut growing tracts may be suggested for adoption of this system and harvest the fruits of newly generated technology.
