Abstract
Mean aerial dry matter yield of some major food crops – Glycine max, Eleusine caracana, Hordeum vulare and Zea mays was recorded by growing them in soils influenced by some tree crop – Alnus nepalensis, Pinus roxburghii, Prunus cerasoides and Sapindus mukorossi. The dry matter accumulation of all the tested food crops increased significantly (P<0.05) under the soils of the tree crops, whereas, the soil from outside of the plantation (control) responded with poor yield of the crops. A. nepalensis and S. mukorossi have the best potential to enhance the yield of the agricultural crops, on the other hand, soils of P. roxburghii yielded poorly and P. cerasoides soils ranked in between these two. Although, yield of G. max (leguminous C3 crop) was not influenced very much by these soils, however, dry matter production of rest of the crops, depended very much on these soil influences (treatments).
