ABSTRACT
Planting patterns have a crucial role in cane and sugar yield. This investigation was performed to determine the ratooning potential of diverse clones of sugarcane under different trench spacing. The study was comprised of different trench spacing i.e., 90, 120, 150 and 180 cm and diverse sugarcane clones i.e., US-272, US-658, US-127 and US-704. The study was conducted in a randomized complete block design with split plot arrangement having three replications. The findings depicted that trench spacing and clones significantly affected sugarcane growth, cane yield and sugar yield. The maximum cane length (250.69 cm), mill-able canes (13.83) and stripped cane yield (107.67 t ha-1) were recorded in 120 cm apart-trenches, whilst minimum cane length (229.11 cm) mill-able canes (12.00) and stripped cane yield (98.17 t ha-1) was noticed in 90 cm spaced trenching. In the case of clones, US-272 had maximum cane length (255.03 cm), un-stripped cane yield (139.43 t ha-1) and stripped cane yield (109.75 t ha-1). Moreover, trench spacing did not affect brix (%), sucrose content SC (%), cane juice purity (CJP) and commercial cane sugar (CCS) (%), however, trench spacing significantly affected the sugar yield. The maximum sugar yield (13.51 t ha-1) was obtained in 120 cm apart trenches and the minimum sugar yield (11.56 t ha-1) was obtained in 90 cm spaced trenches. Amongst clones, maximum brix (24.01%), SC (17.96%), CJP (80.38%), CCS (12.51%) and sugar yield (13.62 t ha-1) were recorded in US-127 and the lowest was noted in US-704 among the clones. In conclusion, sowing in 120 cm apart trenches is a promising practice to obtain the maximum cane and sugar yield from the ratooned sugarcane crop.
