Evaluation of New Canal Point Sugarcane Clones
1997-98 Harvest Season

Table 18. Yields of cane (in metric tons per ha--TC/H) and theoretical recoverable yields of 96° sugar (in kg per metric ton of cane--KS/T and in metric tons per ha--TS/H) from second-ratoon cane on Torry muck and Malabar sand

Clone	Mean yield by soil type, farm, and sampling date
	Cane yield (TC/H)			Sugar yield (KS/T)			Sugar yield (TS/H)
