Effect of bund trees on soil fertility and yield of crops

摘要

A study was conducted on farmers field with tree species viz. Shisham (Dalbergia sissoo Roxb.), bankat (Wendlandia exserta), tar (Borassus flabellifer L.) and khajur (Phoenix sylvestris L. Roxb.) growing on field bunds. Significant higher organic matter and nutrient (NPK) were found in field alongwith shisham having dense canopy cover, whereas grain yield and aerial biomass of crop were significantly lower. Higher soil fertility was found near tree base, while grain yield and aerial vegetative biomass of crops increased with increase in distance from tree base. Shading was the important factor responsible for the lower yield and growth of crops at position closerto tree line especially in shisham.
