Abstract
Effect of various levels of sulphur (50,100 and 150 kg ha-1) with three sources of sulphur fertilizers was studied on sugarcane crop in a field experiment conducted in Typic ustropept at Thiruppuvanam block of Sivagangai district during 2018-2019. The results revealed that the application of sulphur @ 100 kg ha-1 as FeSO4 as soil application along with application of N, P2O5 and K2O on Soil Test Crop Response (STCR) basis registered the maximum nutrient content of N, P, K & S in cane, leaf and total nutrient uptake. The cane yield (162 t ha-1) was maximum at the application of sulphur @ 100 kg ha-1 as FeSO4 followed by the treatment receiving 150 kg ha-1 of sulphur as FeSO4 inconjoint with N, P2O5 and K2O on STCR basis (157.00 t ha-1).
