Subsurface-Applied Coated Nitrogen Fertilizer Enhanced Wheat Production by Improving Nutrient-Use Efficiency with Less Ammonia Volatilization

Nitrogen (N) is an essential plant nutrient, therefore, N-deficient soils affect growth and development. The excessive unwise application of N fertilizers result in nutrient losses lower use efficiency that leads to the low crop productivity. Ammonia volatilization causes a major loss after fertilization environmental pollution. This experiment was conducted evaluate effectiveness coating uncoating fertilizer enhancing yield nutrient-use with reduced ammonia emissions. recommended rate nitrogen phosphorus, urea di-ammonium phosphate (DAP) were coated manually 1% polymer solution. DAP (coated/uncoated) potassium applied at time sowing as subsurface application. While surface Results showed efficiencies wheat found be maximum which increased by 44.57 (N), 44.56 (P) 44.53% (K) higher than uncoated fertilizer. emissions lowest subsurface-applied Thus, via best technique overcome improvement wheat.
