Effect of integrated nitrogen management on nutrient uptake, quality, economics and soil fertility of pearlmillet under rainfed conditions

A B ST R A C T Field experiments were conducted during kharif seasons of 2006 and 2007 to evaluate the effect of integrated nitrogen management nutrient uptake, quality, economics and soil fertility of pearlmillet under rainfed conditions. Applications of 50% RDN through FYM + 50% through urea, 80% RDN through vermicompost + 20% through urea and 25% RDN through FYM + 75% through urea were found the most superior and equally effective treatments in terms of total uptake of nitrogen, phosphorus and potassium, protein content in grain, grain yield, net returns and B:C ratio. Significantly, higher total uptake of nitrogen (66.73 kg/ha), phosphorus (14.48 kg/ha) and potassium (97.16 kg/ha), protein content in grain (11.83%), grain yield (2.22 t/ha) net returns ( 11169/ha) and B:C ratio (1.95) were recorded where 50% RDN through FYM + 50% through urea was applied. Whereas, application of 100% RDN through FYM was proved most superior treatment for improvement in post experiment soil fertility by increased soil organic carbon, N, P and K content
