Food security of vegetable protein is of utmost importance for economic policy of each country, hence there have been actions taken in Poland that lead to the restitution of native production of legumes. The aim of this research has been a comparison of cultivation profitability of four varieties of the pea with the use of two levels of phosphorus fertilization (standard - 70 kg.ha-1 and high - 140 kg.ha-1). This research has been carried out in the years 2013-2015 in an Experimental Station of the Institute of Plant Production in the University of Agriculture in Krakow. It has been proved that a higher dose of phosphorus fertilizers results in the increase in crops only in the years when there was an expanded number of rainfall. It has been pointed out that on average over a span of the whole research, the increased dose of fertilizers has negatively influenced the profitability of production of all pea varieties. This action has put an impact on neither the decrease in crops fluctuation nor profitability. The research has shown that a variety “Mecenas” has the best profitability of production, because with the use of a standard dose of fertilizers, it has given an income surplus over direct costs (between 100% to 145%). Thus, there has been relatively little fluctuation of profitability of production, which weighs in favour of cultivation of the “Mecenas” variety.
