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 was assessed by conducting a pot culture experiment. 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. 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 ).
