A field experiment was conducted in an on going Long-Term Fertilizer Experiment during 2017-18 and 2018-19 at the Research Farm, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur to study the effect of long-term fertilizer application on performance of wheat crop and soil properties. The experiment was conducted in a randomized block design with ten treatments in four replications. The treatments comprised were 50% NPK, 100% NPK, 150% NPK, 100% NPK + Hand weeding, 100% NPK + Zn, 100% NP, 100% N, 100% NPK + FYM, 100% NPK-S and Control. The wheat crop (cv. GW-366) was grown with recommended nutrient dose of 120:80:40 (N: P2O5: K2O) in rabi season. The leaf area index, leaf area duration and relative growth rate was determined at important growth stages viz., crown root initiation, tillering stage, flowering stage, milking stage and at dough stage. The grain and straw yield were recorded at crop harvest. The results revealed that, the wheat responded positively to the balanced nutrition as compared to no fertilization and imbalanced fertilization. The wheat physiology and crop yield showed significant and positive response to 100% NPK + FYM, recommended NPK and super optimal NPK application. The stage wise physiological response of wheat was also observed irrespective of the treatments.
