Abstract

The field experiments conducted in calcareous soils of Coimbatore district to alleviate Fe and Zn deficiencies in sugarcane crop and to maximise the cane yield, showed that calcareous soils with low Fe availability, 100 kg/ha alone as soil application or 50 kg FeSO4 plus FYM at 20 t/ha can be resorted to maximise cane yield of Mandya sugarcane crop. For correcting Fe deficiency in standing crop, one per cent FeSO4 foliar spray can be given on 45th and 90th day after planting. From another field experiment, the results showed that application of ZnSO4 50 kg/ha along with 100 kg FeSO4/ha significantly increased yield of ratoon crop of Co.419 sugarcane over NPK treated control Increase in sucrose content was obtained in the above crop through foliar spray of 0.5% ZnSO4 four times at 30, 50, 70 and 90 days after planting
