An experiment on forage berseem was conducted in the winter season of 2020-21 at ICAR-CIRG, Makhdoom, Mathura (UP) to study the productivity and profitability of forage berseem under varying seed rates and phosphorus fertilization. The treatments consist of seeding rates viz. 20, 25 and 30 kg ha-1 and five levels of phosphorus from 40 to 120 kg ha-1. The experiment was replicated thrice in factorial RBD. The result showed that maximum total green (78.95 t ha-1) and dry (8.65 t ha-1) forage yield, total nutrient uptake and maximum BC ratio ratio of forage berseem was found with 30 kg of seed rate ha-1. However, 25 and 30 kg of seed rate recorded at par value of yield, nutrient uptake and economics. Further, among different phosphorus levels, 120 kg P2O5 ha-1 registered highest total forage yield (83.74 t ha-1); total nutrient uptake and BC ratio of forage berseem. However, 100 and 120 kg P2O5 ha-1 was found at par in terms of yield, nutrient content and uptake and economics in forage berseem.
