A two year field experiment on rice crop was conducted on sandy loam soil at Crop Research Centre of SardarVallabhbhai Patel University of Agriculture and Technology, Meerut, during 2009 and 2010 to evaluate the impact of enriched biocompost application in integration with chemical fertilizers on soil fertility and productivity of rice crop in rice-wheat system. Growth parameters, yield attributing characters, grain and straw yield of rice crop was affected significantly by different treatments. Nutrient assimilation at different stages by rice crop also varied significantly due to application of different treatments in the study. Rice grain yield increased significantly due to application of additional 25 % NPK over 100 %. Growth parameters and yield attributing characters, improved slightly due to application of biocompost. Application of higher levels of biocompost along with 75 % NPK produced significantly higher grain yield of rice than T2. No significant effect of biocompost enrichment of biocompost was found although slightly higher grain yield of rice was found with the application of enriched biocompost than unenriched at particular NPK level. Micro nutrient contents of both the crops were slightly higher due biocompost application. Availability of primary macro nutrients was slightly higher in the plots receiving super optimal application of NPK or higher biocompost levels.
