Description

Effects of phosphate application on the growth, yield and quality of sugarcane (Saccharum officinarum L.) were studied on the soils having various phosphorus levels. Superphosphate was applied to bring the available soil P at 5, 15, 25 and 35 mg P2O5 100 g-1 designated as A, B, C and D levels, respectively. Leaf area index (LAI) and dry matter increased on the higher P plots over the lower P plots. The highest cane yield (74 t ha-1) and sugar yield (10.2 t ha- 1) were obtained from the B plot and the lowest cane yield (51 t ha-1) and sugar yield (6.9 t ha-1) were from the A plot. The D plot failed to give the highest cane and sugar yield due to lower millable canes accompanied with poor juice quality. Heavy P application showed bad effects on leaf quality by decreasing N, K, Zn and Cu contents.
