Maximizing nutrient uptake in hybrid maize via advanced nitrogen management techniques

A field study at PJTSAU, Telangana, during Kharif 2019-20, investigated nitrogen management in hybrid maize using hand-held decision tools. Treatments included various nitrogen rates and thresholds for NDVI, LCC, and SPAD meters. Green Seeker at NDVI 0.8 significantly improved N, P, and K uptake (225.5, 35.9, 333.9 kg/ha) compared to recommended nitrogen doses and control. Results indicated precision nitrogen management's effectiveness in enhancing nutrient uptake, crucial for maize productivity.
