Abstract: An experiment was conducted for two consecutive cropping seasons during 2002-03 and 2003-04 at Lucknow, to evaluate 3 sugarcane (Saccharum officinarum) genotypes ('CoLk 9411', 'CoLk 9412' and 'CoLk 94184') under 3 N, P and K levels (150, 200, 250 kg N; 45, 60, 75 kg P and 45, 60, 75 kg K/ha) to identify tillering behaviour, growth and sucrose accumulation of these genotypes under different planting seasons. Tiller number increased (149 500/ha and 140 600/ha in spring and summer cane respectively) with the increase in the nutrient doses up to 200, 60 and 60 kg NPK/ha. Planting seasons also influenced tillering pattern significantly (144 900/ha in spring and 127 300/ha in summer planted cane during September). Spring planted sugarcane gave significantly greater number of tillers compared to summer planted cane. 'CoLk 94184' gave the highest number of tillers (197 800/ha and 159 200/ha in spring and summer planted cane respectively) as compared to 'CoLk 9411' and 'CoLk 9412'. Significantly higher cane yield (77.4 tonnes/ha) was harvested with genotype 'CoLk 94184'. It also had the higher pol percentage in juice (18.49) at 10-month stage in spring planted cane. Individual cane length (207.4 cm) and cane weight (693.8 g) in spring planted cane increased significantly up to 200,60 and 60 kg NPK/ha. Ratoon of the genotype 'CoLk 94184' gave highest number of millable canes (133 900/ha) and higher cane length (186.8 cm). Maximum ratoon yield (70.46 tonnes/ha) and commercial cane sugar (9.39 tonnes/ha) were obtained with 'CoLk 94184'. Fertility level of 200, 60, 60 kg NPK/ha was optimum for better growth, juice quality and cane yield during spring as well as summer planting in north Indian conditions.
