A field experiment was conducted at Instructional-cum-Research Farm (ICR) of Assam Agricultural University, Jorhat during summer season of the year 2016 to evaluate the varietal response and effective integrated nutrient management practice for growth and yield of maize. The experiment was laid out in split plot design and replicated thrice. The soil of the experimental site was sandy loam in texture, acidic in reaction (pH 4.94), medium in organic carbon (0.72%), low in available N (159 kg/ha) and P2O5 (23.78 kg/ha) and medium in available K2O (160.5 kg/ha). Two composite variety of maize viz., RCM-76 and DA-61-A were sown in 18th of March (2016) and harvested by two picking on 24th June and 4th July. Experimental findings revealed that the nitrogen, phosphorus and potassium uptake by crop was highest (144.06 kg/ha N, 26.7 kg/ha P2O5, 141.9 kg/ha K2O) under 50% RD of N through fertilizer + 50% N replaced by Enriched compost with DA-61-A variety. However the nutrient status of the soil did not differ significantly, the available nutrient status decreased as compared to initial status.
