The experiment was laid out in a Factorial Randomized Block Design with sixteen treatments and replicated three times. There was no significant difference among the treatments with respect to nitrogen, phosphorus and potassium content of leaves under different levels of planting geometry and interaction effect. But different nutrient levels had significant influence in the N, P and K content in isabgol plant. Higher N (3.76%), P (0.7%) and K (3.59 %) content in the leaves was observed when plants supplied with 75 % RDF (37.5:18.75:22.50 + 7.5 t FYM). The maximum uptake of N (229.11 kg /ha), P (43.98 kg /ha) and K (218.46 kg /ha) was found at row spacing of 22.5 cm, which was significantly superior to other spacing levels.Nutrients had significantly influenced the N, P and K uptake. The 75 % RDF (37.5:18.75:22.50 + 7.5 t FYM) level recorded maximum uptake of N (166.36 kg /ha), P (32.13 kg /ha) and K (158.39 kg /ha), which was significantly superior to all other nutrient levels.Among the interactions, 22.5 cm row spacing + 75 % RDF (37.5:18.75:22.50 + 7.5 t FYM) recorded significantly maximum N, P and K uptake (252.05, 49.31 and 238.85 kg/ha respectively).
