Nitrogen application under different methods of planting of sugarcane

The sugarcane planting with wide bed and furrow paired row planting, half ridge open furrow irrigation planting, and wider planting methods improved growth, yield, and yield attributes and nutrients uptake of N, P, and K over conventional planting. The higher agronomic nitrogen use efficiency (NUE), percent nitrogen recovery, and physiological nitrogen use efficiency were also recorded in the wide bed and furrow paired row planting method. The cane quality parameters viz. Brix Percent, Pol Percent, Purity Percent, and CCS Percent were not significantly affected by different planting methods and levels of nitrogen. Results obtained with wide bed and furrow paired row planting proved to be a most promising method which gave more net return and benefit: cost ratio. The highest productivity and net return were obtained at 150 kg N ha-1.
