Abstract:
Soil fertility has been hampered due to excessive use of synthetic fertilizers as baby corn is an exhaustive crop and it requires ample of nutrients to meet its nutritional requirements. But at the same time soil health should not be deteriorated by applying high doses of primary nutrients. So, there is a need of eco-friendly alternative system for better utilization of resources and to get high productivity with good quality. Keeping these points in mind, the present study was carried out to find out the suitable management system to enhance the productivity of baby corn under Punjab condition for sustainable agriculture. The investigation was carried out during rabi season 2021-22 at Lovely Professional University, Phagwara in randomised block design with three replications, nine treatments with different combinations of nitrogen, phosphorus, zinc and Azotobacter in baby corn. Data was collected from four randomly selected plants from each plot and analysis was done and it was observed that the growth characters and yield were significantly affected by various doses of nutrients. Application of 160 kg N + 120 kg P + 5 kg Zn + Azotobacter showed maximum plant height (129.83 and 222.7 cm), number of leaves (12.33 and 13.76), stem girth (28.64 and 29.96 mm) at 60 and 90 DAS, respectively and highest cob yield (44.92 q /ha) which was significantly at par with treatment T6, T7 and T8. It indicates that the integrated nutrient management has positive effect on growth and yield of baby corn.
