EFFECT OF PHOSPHORUS FERTILIZATION AND FARMYARD MANURE APPLICATION ON GROWHT AND YIELD OF PEANUT

This work aims to study the effect of farmyard manure addition in combined with different rates of inorganic phosphate fertilizer on the growth and yield of peanut grown in sandy soil. sprinkler irrigation system was used during two summer seasons (2005 and 2006) at ahmed ramy village , el-bustan, el-beheira governorate. the natural organic manure was added for improving soil characteristics as well as enhancing nutrients availability were taken into consideration. the obtained results strongly confirmed that application of farmyard manure increased organic matter content, cec and decreased the hydraulic conductivity of the investigated soil. the results also showed that the application of organic materials either alone or in combination with inorganic p fertilizers caused a substantial increase in available n, p, k and micro nutrients (fe, mn, cu, zn) as well as peanut yield (straw and kernel). the highest yield (biomass and kernel) and other growth parameters were obtained when farmyard manure was applied in combination with the recommended dose of inorganic phosphorus fertilizer. the results also showed that application of farmyard manure combined with inorganic phosphorus fertilizer caused a substantial increase in the peanut kernel content from npk and nutrients availability in soil.
