The aim of this study was to evaluate the agroeconomic yield of 'Luciana n.º 50' pea grown within three spacings between plants (5.0; 7.5 and 10.0 cm), with and without soil covering with poultry litter. Treatments were arranged in a 3x2 factorial in randomized complete block design with five replications. The highest fresh (8.33 t ha-1) and dry (2.02 t ha-1) shoot weights were of plants grown with spacing of 7.5 cm between plants, and the lowest fresh (7.87 t ha-1) and dry (1.82 t ha-1) weights were of those with 10.0 cm. The highest fresh weight of commercial pods (3.08 t ha-1) was found in plants grown with spacing of 5.0 cm, exceeding by 0.33 t ha-1 those with 7.5 cm. Fresh weight yield of commercial pods of plants grown without the use of poultry litter exceeded by 0.46 t ha-1 those grown with covering. The highest yield of commercial grains (2.24 t ha-1) was obtained with plants grown in soil without covering. Considering the yield of commercial grains and the estimative of net income (R$ 5145.60 ha-1), it is concluded that the Luciana n.º 50 cultivar should be grown with spacing of 5.0 cm between plants per plot and without the use of poultry litter.
