Abstract: A field experiment was carried out during kharif season of 2016 at Crop research farm TCA Dholi, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, (Bihar) to study the “Effect of nutrient management on growth of maize (Zea mays L.) Under different tillage practices”. The experiment was laid out in a split plot design with three replication. Main plot consist of three different tillage practices viz., a) Zero tillage (ZT), b) Conventional tillage (CT) and c) Bed planting (BT) and sub plot comprised of four different level of nutrient management viz., a) Recommended dose of fertilizer (RDF) (120, 60 and 50 kg/ha N, P2O5 and K2O), b) Site Specific Nutrient Management (SSNM) based on nutrient expert and c) Farmers practice (FP) (150% of RDF + 10 ton FYM). Growth attributes i.e., plant height, leaf area, days to 50% tasseling, days to 50% silking, plant population at maturity and dry matter accumulation were found significantly higher under bed planting tillage practices over zero tillage and conventional tillage practices. Among the different nutrient management practices, farmers practices was reported significantly higher growth attributes than recommended dose of fertilizer but statistically at par with site specific nutrient management practices.
