Abstract
Field experiments were conducted to study the effects of combined application of nitrogen (N), phosphorus (P) and potassium (K) on growth, yield quality and nutrient balance of sugarcane with subsurface drip irrigation by using the sugarcane variety ROC89/1626 and adopting “3414” project design. It was observed that the appropriate rate of N, P2O5 and K2O increased the plant height, cane yield and cane quality of sugarcane under the experimental conditions. The fertigation model recommended for highest cane yield was 367.2 kg N, 162.6 kg P2O5 and 423.3 kg K2O per ha. The highest cane yield recorded with this dose was 101.8 t/ha. The best fertigation model recommended was 340.1 kg N, 141.9 kg P2O5 and 401.1 kg K2O per ha for the cane yield of 101.6 t/ha.
