A field experiment was conducted at Regional Research Station, Karnal, CCS Haryana Agricultural University during spring 2017-18. The experiment was laid out in split plot design with three replications. The treatments comprises of four methods of planting viz. conventional planting at 75 cm (M1), half ridge open furrow irrigation planting at 75 cm (M2), wide bed and furrow paired row planting (M3) and wider planting (M4) at 120 cm and six different nitrogen levels viz. control (N1), 75 (N2), 100 (N3), 125 (N4), 150 (N5), 175 kg N ha-1 (N6). The results revealed that different planting methods fail to exert any significant influence on the nitrogen, phosphorus and potassium content (%) in cane, green top and whole plant. Application of different levels of nitrogen results significant increase in nitrogen concentration and uptake in cane and plant with increasing the dose of nitrogen except green top. The significantly higher N content (0.33% in cane, 0.69% in sugarcane plant) was recorded with the application 175 kg N/kg over control which was at par with 150 kg N/ha. The different level of nitrogen application had non-significant effect on P and K content in cane, green top as well as plant. However, significantly higher uptake of N, P and K was observed in wide bed and furrow paired row planting than conventional planting. Planting methods did not bring any significant variation in respect of available nutrients (N, P and K) in the soil, however, Increasing trend of available nitrogen was observed with increasing dose of nitrogen. The significantly higher available nitrogen (148.5kg/ha) was obtained with application of 175 kg N/ha over control.
