An experiment was conducted in the affiliation of Department of Agronomy, College of Agriculture, Bijapur and  Research and Development division, Nandi Co-operative Sugar Factory, Galagali, Karnataka, India during 2004 and 2005 on medium black soil to study the efficacy of using leaf colour chart (LCC)  for nitrogen management in sugarcane.   The experiment was laid out in randomized block design with five replications and four treatments (N as per LCC index 4, 5 and 6 and N as per recommended practice 250 kg /ha in 4 splits).  The cane yield and net return recorded with application of N as per LCC 6 (152.2 t/ha and 1.25 lakh/ha) and LCC 5 found on par with each other (145.10 t/ha and 1.18 lakh/ha).  Both the treatments were significantly superior than application of N as per LCC 4 (101.8 t/ha and 0.69 lakh/ha) and LCC N (124.3 t/ha and 0.94 lakh/ha).  Similarly, significantly higher cane height (238 and 233 cm), single cane weight (1.24 and 1.29 kg) and B: C ratio (2.11 and  2.17)  were recorded in treatments LCC 5 and 6 respectively as compared to LCC 4 (184 cm, 0.95 kg  and 1.29) and recommended N treatments (202 cm, 1.15 kg and 1.71)
