4. INFLUENCE OF CUSTOMIZED DOSES OF FERTILIZER ON N_P_K AVAILABILITY & UPTAKE IN LATE SOWN WHEAT By SUVARNA T. KALE1 AND ANANT R. MALI2
Abstract
Chemical analysis revealed the uptake of Nitrogen, phosphorus and potassium increased with increasing levels of fertilizer, uptake was more with application of 150:75:75 kg NPK/ha over rest of the fertilizer levels. The available nitrogen, phosphorus and potassium, left in soil after the harvest was significantly more with application of 150:75:75 kg NPK/ ha over rest of the fertilizer levels. Although, the highest grain yield was observed at fertilizer dose 120:60:60 NPK kg/ha than 150:75:75 NPK kg/ha.
KEY WORDS: Available NPK, Fertigation, NPK uptake, Wheat.
