Abstract:
In race towards high production and profit from agriculture, the farmers are adopting abnormal production technologies like heavy and injudicious use of chemical fertilizers that have reduced the factor productivity, besides, eroding biodiversity and enhancing environmental pollution. Therefore, its an urgent need to optimize the integrated nutrient management in different crops including baby corn. 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 evaluate the influence of integrated nutrient management on yield and yield attributing characters of baby corn. In yield attributing characters, different integrated nutrient management practices produced significant values of baby corn length at 1^st pick, 2^nd pick and on the average value of baby corn length. The 100% NPK+Azot+Azos produced the longest baby corn at 1^st pick, while at 2^nd pick, the longest baby corn were produced at 75% NPK+Azot+Azos. The girth of the baby corn did not affect significantly by different integrated nutrient management practices except the average values where 75% NPK+Azot+Azos and 100% NPK+Azot+Azos gave significantly higher girth of baby corn. Significantly higher baby cob yield was recorded at application of 100% NPK+Azot+Azos that remained non-significant with 75% NPK+Azot+Azos. Both the treatments produced 6.7% and 6% higher baby cob yield, respectively than 100% NPK application. The baby corn yield was recorded significantly higher at 100% NPK+Azot+Azos that remained non-significant with 75% NPK+Azot+Azos and it had 7.9 and 3.5% greater baby corn yield than 100% NPK and 75% NPK+Azot+Azos, respectively. The green fodder yield was found highest with application of 100% NPK+Azot+Azos that remained non-significant with all the treatments except control. Thus the integrated use of nutrients including low cost biofertilizers proved to be beneficial for sustaining crop productivity.
