Abstract:
A field experiment was carried out during the rabi seasons of the year 2021-22 and 2022-23 at College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat, with a view to study the residual effect of nitrogen management and direct application of fertilizer on chemical and biological properties of soil of chickpea under pearl millet-chickpea cropping sequence. The experiment was laid out in a Split Plot Design (SPD) with twelve treatment combinations. The results obtained from the experiment the significantly higher chemical properties of soil viz., available N and P₂O₅ were recorded higher in treatment combination with 50% RDN through urea + 75% RDN through castor cake + Bio NPK consortium to preceding kharif-pearl millet and 100% RDF direct application to succeeding chickpea. The organic carbon, EC, pH and available K₂O does not influenced by any treatment in chickpea. Biological property like total microbial count were recorded higher under treatment combination of 100% RDN through castor cake applied to previous pearl millet along with 0% RDF to chickpea.
