Effect of integrated nutrient management on nitrogen dynamics in soil of rice -potato based cropping sequence
Journal Title: Journal of Applied and Natural Science - Year 2015, Vol 7, Issue 2
Abstract
The integrated nutrient management (INM) has profound influence on sustaining crop productivity and fertility status of soil. The manurial field experiment was conducted at Paschim Medinipur, West Bengal for evaluating the performance of chemical fertilizer and organic manure on nitrogen availability in different forms in soil and also on the content of nitrogen in different parts of rice (Oryza sativa cv. Annada) and potato (Solanum tuberosum cv. Kufrijyoti) during different growth stages. Application of FYM and RDF150 in combination had good impact on nitrogen dynamics related to crop growth among other treatment combinations. FYM and RDF150 alone also imparted good impact on nutrient availability and yield of two experiment crops (rice and potato). Experiment revealed that incorporation of commercial concentrated organic manure with RDF150 exerted good impact besides FYM combination with inorganic fertilizers.
