Effect of method of gap-filling and gypsum application on yield and quality of sugarcane ratoon

The field experiment was conducted to study the effect of method of gap-filling and gypsum application on cane and sugar yield of sugarcane ratoon on April-May planted crop during 1998–2000 in sodic soils at Anbil Dharmalingam Agricultural College and Research Institute, Trichirappalli. The results envisaged that gap-filling with sprouted seedlings of ratoon field had the highest mean cane and sugar yield of 99.3 and 13.0 tonnes/ha respectively. Gypsum application in furrow has the mean cane and sugar yield of 99.7 and 12.9 tonnes/ha. Interaction of the above treatments also resulted in high yield of cane and sugar yield in both years.
