Abstract: A field experiment was conducted to assess the effect of nitrogen levels and cattle urine foliar sprays on yield and economics of maize (Zea mays L.) at Agronomy Farm, College of Agriculture, Pune, during Kharif- 2019. The experiment consisted of 16 treatment combinations based on four levels of the recommended dose of nitrogen (@ 0, 50, 75 and 100%) through urea and four levels of cattle urine foliar spray (@ 0, 5, 10 and 15%) taken at 25, 45 and 60 DAS replicated thrice in Factorial Randomized Block Design. The results revealed that the grain and stover yield of maize were influenced significantly and the statistically higher grain and stover yield was recorded with the application of 100% RDN (120 kg ha^-1). While the application of 10% cattle urine sprays recorded the statistically higher grain and stover yield which was followed by 15% cattle urine spray. In respect to the economics of maize, higher gross monetary returns, net monetary returns and B:C ratio was recorded with the application of 100% RDN whereas, the application of 10% cattle urine spray recorded statistically higher net monetary returns, gross monetary returns and B:C ratio followed by 15% foliar spray of cattle urine.
