In irder the Visia faba L. nutrition to be optimized a field experiment on lye-meadow maroon soil has been made in Maritsa Vegetable Reasearch Institute, Plovdiv for two years. A biometric analysis of plant aggregation(stems, leaves, fruits) and a chemical analysis for N, P2O5 and K2O content in the plant organs are made. The biological export of alimentary elements from the plants in hectare and the consumption of N, P2O5 and K2O for formation of 1000 kg production are defined. By the made algorithms and with the assistance of the production function the mineral nutrition for high, quality and environmentally clean yield is optimized.
