Abstract: The performance of mulberry (Morus alba cv. S-1635) grown in sandy clay loam soil that had been treated with S fertilizer through elemental S (ES) or ammonium sulfate (AS) at various rates (0, 20, 30 and 40 kg/ha) from 2006-07 to 2009-10 was studied in Berhampore, West Bengal, India, during 2010-11. Only the highest rate of S had a significant residual effect on leaf yield. The S fertilizer treatments except 20 kg S/ha applied through ES markedly increased shoot yields. S uptake by leaves was significantly enhanced only by ES at 40 kg/ha, and AS at 30 and 40 kg/ha. However, all the rates of S had significant residual effects on S uptake by shoots. The increase in the rate of S increased the amount of available S in the soil but reduced soil pH.
