Performance of new early genotypes of sugarcane (Saccharum spp. hybrid complex) as influenced by row spacing

Field experiment was conducted during 2017-18 at Sugarcane Research Institute, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar to study the effect of row spacing on yield and quality of early maturing sugarcane genotypes. Treatment included two row spacing (90 and 120 cm) and five genotypes viz., ‘CoLk 12207’, ‘CoP 12436’, ‘CoSe 12451’, ‘BO 130’ and ‘CoSe 95422’. Significantly higher plant population, leaf area index (4.18), dry matter accumulation (34.8 t/ ha) and millable canes (126, 200/ ha) were recorded with 90 cm row spacing gave significantly highest cane (96.2 t/ ha) and sugar yield (11.6 t/ ha). Results showed that genotype CoSe 95422 superseded other genotypes in growth and yield attributing characters. Maximum cane yield (104.4 t/ ha) was noticed due to the genotypes CoSe 95422. However, maximum brix (20.3%), pol (18.13%) and CCS percent (12.60%) were noted with the genotype CoLk 12207 which was statistically similar to BO 130. Significantly higher sugar yield (12.4 t/ha) was obtained with the genotype CoSe 95422 which was statistically comparable to CoLk 12207 and CoSe 12451.
