Chemical quality and yield performance were studied in six new sugarcane genotypes at
normal and water-logging condition. The highest chemical indices, Brix % (22.20) and
pol % (20.53) were found in January’ 2002 in I-93/93 and I-110/93 respectively and the
lowest in I-39/94 (Brix %: 14.93; pol %: 12.52) at water-logged cultivated cane in all
months. The highest of purity % (95.79) and recovery % (13.05) were found in I-110/93
in the month December 2001 and January’ 2002 respectively and the lowest in Isd 20
(purity % : 77.44; recovery % 6.49 in September 2001) at water-logged and normal
cultivated cane respectively. The highest R.S. % (1.51) was found in I-39/94 in all
months and the lowest in I-110/93 (0.09) at water-logged cultivated cane. Result showed
that the highest tiller (183.3×1000 ha–1 in I-110/93), millable cane (117.8×1000 ha–1 in
I-8/95), Yield (162.8 t ha–1 in I-8/95) and TSH (16.63 ton sugar ha–1 in I-110/93) were
found in normal cultivated and the lowest were found in water-logged cultivated
sugarcane (tiller 107.6×1000 ha–1 in Isd 20; millable cane 73.38×1000 ha–1 in Isd 30;
yield 59.4 t ha–1 in Isd 20 and TSH 6.75 ton sugar ha–1 in Isd 20). It is concluded that the
highest percentage in juice quality were found in water-logged condition cultivated cane,
on the other hand growth & yield performance were also found in highest in normal
cultivated cane. In aspect of sugar production some tested cultivars showed (Isd-20, I-93/93 and I-8/95) similar performance in normal and water-logged cultivated sugarcane
due to genetic potentiality and environmental adaptation on quality, yield and growth.
