Abstract

To study the fertilizers and humic acid on nutrient uptake in Alfisol and Inceptisol, two field experiments were conducted during rabi 2001 with various levels of fertilizers and humic acid treatments. A large increase was recorded in the uptake of nutrients for the application of humic acid (HA) upto 40 kg ha'. The significant increase of N, P and K uptake were recorded upto 20 and 10 kg HA ha respectively in both Alfisol and Inceptisol. In the presence of humic acid, the effect of 75 and 100% NPK fertilizers on nutrient uptake and grain yield was comparable with each other.
