Effect of FYM, Gliricidia Compost and azotobacter in Conjunction with Nitrogen Fertilizer on Yield Performance and Physico-Chemical Properties of a Typic ustipsamments

A field experiment was conducted on loamy sand soil of the S.D. Agricultural University, Sardar Krushinagar in 2002 to study the effect of organic, inorganic and biofertilizer on chemical and physical properties of soil. The result indicated that application of 75 % RDN (Urea) + 25% (FYM) with Azotobacter recorded higher grain and stover yield. The soil physical properties like infiltration rate, bulk density and water holding capacity improved by application of higher dose of organic manure while, soil moisture significantly higher in 50% RDN through urea + 50 % RDN through FYM treatment. Application of different nitrogen management decreased the pH and increased the EC than initial value of soil test. The maximum available N and S content in soil recorded with application of 75 % RDN through urea +25 % RDN through gliricidia compost treatments. The organic carbon, available P and K content in soil was maximum under application of 50 % RDN urea and 50 % RDN through gliricidia compost, while maximum DTPA-extractable Zn and Fe content in soil was noted under application of 50-50 % RDN applied through urea and gliricidia compost.
