A field experiment was conducted during winter season of 2006–07 and 2007–2008 to study the effect of different fertility levels (Fertility level F₁: 30-20-2.5, P₂O₅-S-Zn kg/ha and Fertility level F₂: 60-40-5, P₂O₅-S-Zn kg/ha) and micronutrients on plant growth, nodulation, production potential of pea. Results indicated that fertility level F₂ (60-40-5, P₂O₅-S-Zn kg/ha) was found most effective in enhancing the plant growth, nodulation, yield attributes, yield, nutrient content in nodules and nutrient uptake by crop. Improvement in different form of N viz NH₄-N, NO₃-N, organic N, available N and total nitrogen were registered with higher fertility level. Amongst the micronutrient, combined application of micronutrients enhanced the plant growth, nodulation, yield attributes, yield, nutrient content in nodule and nutrient uptake. NH₄-N, NO₃-N, organic N, available N and total nitrogen were also recorded higher with combined application of micronutrients. Grain yield and nutrient (N, P and S) uptake by crop also increased to a great extent by the combined application of micronutrient (B 0.3% + Co 2+ Mo 1 kg/ha) under fertility level F₂.
