Evaluation of planting geometry and different varieties on growth and yield of spring planted sugarcane

A field experiment was conducted at Central Sugarcane Research Station, Padegaon, Tal: Phaltan, Dist: Satara, Maharashtra during 2011- 12 to 2013- 14 to evaluate planting geometry and different varieties in spring planted sugarcane. Four levels of planting distance viz. 100 cm row distance, 120 cm row distance, 150 cm row distance and 30 x 150 cm row distance in main plots and four genotypes i.e. CoM 0265, Co 86032, Co 94012 and CoC 671 in sub plots laid out in split plot design with three replications. The spring sugarcane planted with row spacing of 120 cm recorded significantly the highest millable height (298 cm) and found at par with 150 cm row spacing. A similar trend was noticed for the cane girth (10.6 cm) and number of millable canes ha-1 (89630 ha-1). The row spacing of 120 cm recorded significantly the highest cane yield (122.33 t ha-1) and CCS yield (17.42 t ha-1) and found at par with the row spacing of 150 cm for both cane yield (116.89 t ha-1) and CCS yield (16.50 t ha-1). Among the varietal response, the significantly the highest cane yield (136.69 t ha-1) and CCS (19.20 t ha-1) yield were recorded with the genotype CoM 0265 followed by Co 86032 (121.31 and 17.27 t ha-1). The sugarcane genotype CoC 671 was found to be the most superior with respect to juice quality.
