A pot culture experiment was conducted to assess the effect of nitrogen and foliar sprays of cattle urine on growth, yield and nutrient uptake by maize (fodder) grown on Inceptisol at the Division of Soil Science and Agricultural Chemistry and Division of Animal Husbandry and Dairy Science, College of Agriculture, Pune, during Kharif-2018. The experiment consisted of 12 treatment combinations based on three levels of recommended dose of nitrogen (@ 0, 75 and 100 %) through urea and four levels of cattle urine foliar spray (@ 0, 5, 10 and 15 %) taken at 25, 45 and 65 DAS replicated thrice in Factorial Completely Randomized Design. The results revealed that application of 75% N through urea recorded significantly higher plant height, number of functional leaves and leaf area at 30, 50 and 70 DAS of fodder maize which was found to be at par with 100 % N through urea. While cattle urine foliar sprays @ 10 % taken at 25, 45 and 65 DAS was found superior for plant height, number of functional leaves and leaf area of fodder maize at 30, 50 and 70 DAS which was closely followed by 15 % cattle urine foliar spray. Interaction effect between N fertilizers and foliar sprays of cattle urine was found non-significant but combine application of 75% N through urea along with three foliar sprays of 10% cattle urine was recorded numerically higher plant height, number of functional leaves and leaf area of fodder maize. Statistically at par green fodder yield of maize was recorded with the application of either 75 % N (971.75 g pot-1) or 100 % N (962.83 g pot-1) through urea or foliar sprays of cattle urine either @ 10 % (889.11 g pot-1) or 15 % (821.78 g pot-1). Significantly higher N (3.54 g pot-1), P (0.90 g pot-1) and K (4.84 g pot-1) uptake by fodder maize was reported with the application of 100 % N through urea which was followed by 75% N for N (2.85 g pot-1), P (0.76 g pot-1) and K (4.34 g pot-1). However, application of cattle urine foliar sprays @ 15% recorded significantly higher N (3.15 g pot-1) uptake by fodder maize which was closely followed by 10% (2.69 g pot-1). Higher P uptake by fodder maize was observed with 10% cattle urine foliar spray (0.83 g pot-1) which was followed by 15% (0.75 g pot-1) however 10% cattle urine foliar sprays recorded significantly higher K ( 4.51g pot-1) uptake by fodder maize than rest of treatment.
