Influence of Sulphur Fertilization on Yield, Nutrient Content and Uptake by Sugarcane in Sulphur Deficient soil of Thiruppuvanam Block of Sivagangai District

摘要

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 FeSO_(4) as soil application along with application of N, P_(2)O_(5) and K_(2)O 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 FeSO_(4) followed by the treatment receiving 150 kg ha~(-1) of sulphur as FeSO_(4 )inconjoint with N, P_(2)O_(5) and K_(2)O on STCR basis (157.00 t ha~(-1)).
