An experiment was conducted at Agricultural Research Station (Paddy), Sirsi, Karnataka, India during kharif seasons of 2000, 2001 and 2002 on a fixed site to study the efficacy of using Leaf Colour Chart (LCC) for integrated nitrogen management in rainfed lowland rice. The experiment was  laid out in split plot design with three main plot treatments (no manure, FYM 10 t ha-1 and eupatorium 10t ha-1) and four sub plot treatments (N as per LCC index 3.0,4.0, and 5.0 and N as per recommended practice (75 kg ha-1). The grain yield and net return recorded with application of N as per LCC 4.0 (5880 kg and Rs. 24945 ha-1, respectively) and N as per practice (5940 kg and Rs. 25585 ha-1, respectively) was found on par with each other. There was no significant difference in grain yield and net returns due to different organic manure treatments. The grain yield recorded with LCC 4.0, LCC 5.0 and N as per package when applied with either eupatorium or FYM was on par with each other. Whereas, net return realized with LCC 4.0, LCC 5.0 and N as per package was on par only when combined with eupatorium. With no manure and FYM, the net return with LCC 4.0 was found on par with that of N as per package only. The amount of N added in eupatorium + LCC 4.0 was least (30 kg ha-1). Still, the yield levels and net returns realized with this treatment were on par with eupatorium + LCC 5.0 and eupatorium + N as per package, were the amount of N applied was more (122 and 75 kg N ha-1, respectively).
