Abstract: Integrated Nutrient Management (INM) refers to judicious application of different nutrient sources in balanced proportion for sustaining soil and crop productivity. Biofertlizers are an important component of integrated nutrient management system because of its significant role in sustaining the soil properties and increasing nutrient availability. Nutrient management is of great importance for higher baby corn production as it responds to higher doses of fertilizer. In addition, better nutrient content and uptake leads to higher yield. The present study was thus carried out during Kharif season 2015 at the Instructional Dairy Farm (IDF), Nagla, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Uttarakhand to analyse the nutrient content and uptake in baby corn under the effect of integrated nutrient management. The experimental design was Randomized Block Design with 11 treatments consisting of sole application of NPK fertilizer, sole application of Azotobacter and Azospirillum, and application of Azotobacter and Azospirillum along with NPK fertilizer. The study revealed that N, P and K content of baby corn increased with increasing level of chemical as well as biofertilizers and significantly higher N, P and K content of baby corn was recorded at application of 100% NPK+Azot+Azos. Green fodder had higher N and K content at application of 100% NPK+Azot+Azos, whereas the P content remained non significant with highest value at 100% NPK+Azot+Azos. Significantly higher N, P and K uptake was recorded at application of 100% NPK+Azot+Azos that remained non significant with 75% NPK+Azot+Azos at K uptake. But the N, P and K uptake in green fodder was found significantly higher at application of 100% NPK+Azot+Azos that remained non significant with 75% NPK+Azot+Azos and 100% NPK for N and P uptake and 75% NPK+Azot+Azos for K uptake. Highest total N, P and K uptake was found at 100% NPK+Azot+Azos that remained non significant with 75% NPK+Azot+Azos for total N and K uptake. Thus, INM in baby corn is of immense importance for higher nutrient content and uptake.
