A field experiment was conducted during three consecutive years of 2000-01 to 2002-03 to study the nutrient management on yield, quality and fertility status in tobacco based intercropping system in North Bihar. Results revealed that significantly highest cured and first grade leaf yield of tobacco was obtained in tobacco+garlic than other intercropping systems. Highest net and gross return and cost: benefit ratio were realized in tobacco+garlic followed by tobacco+rajmash and tobacco+potato intercropping systems. Application of 100% recommended dose of fertilizers (RDF) produced significantly highest cured and first grade leaf yield of tobacco as compared to rest of the fertility levels. Application of 100% RDF registered more gross and net returns and cost: benefit ratio. The physical parameters of maturity score was recorded more in tobacco+garlic intercropping and application of 100% RDF. Physical and chemical compositions of soil after harvest of tobacco was restored more in 100% RDF along with tobacco+garlic intercropping.
