A field experiment was conducted during rabi season of the year 2011–12 to study the nutrient content, uptake, quality and yield of direct seeded rabi fennel (Foeniculum vulgare Mill.) to varying levels of nitrogen and phosphorus. There was a significant effect of nitrogen and phosphorus levels on nutrient content, uptake, quality and yield. Significantly the highest nutrient content, uptake and seed yield (18.67 q/ha) were recorded under 120 kg N/ha (N3) which were at par with 90 kg N/ha (N2). Application of phosphorus at 60 kg P2O5/ha(P2) registered significantly the highest nutrient content, uptake and yield and were found at par with 30 kg P2O5/ha (P1).
