Abstract
In the rigion Nordeste, the peanutis cultivated almost exclusively by family agriculture producers with low technological levels, in addition to the low use of inputs, essential to ensure better productivity. Objective to evaluate the performance and productivity of peanut subjected to doses of fertilization and spacing between plants, in the rainfed system and irrigation system. The experiment was conducted at the Federal University of cariri. Two experiments were conducted in randomized blocks in parcel scheme subdivided, with four replicates.The plots were four doses of fertilization on sowing (0, 50, 100 and 150%) and the subplots two spaces between plants (10 and 20 cm). The peanut cultivar used was the BRS151L7. Sowing was carried out manually, depositing-if 5 and 10 as the spacing between plants. The harvest was carried out manually to 90 days after sowing.The variables population initial and final population showed significant (p < 0.01) to the spacing between plants in system rainfed and irrigation system. The mass of plants and grains per plant showed significant difference to 1% in the spacing for the irrigation system. In the fertilizing factor, the height of plants was the only variable thatshowed significance (p < 0.05). The application of 80% of the recommended dose of phosphorus and potassium is enough to meet the need of culture. The 10 cm spacing between plants was the best for culture.The use of supplemental irrigation has increased by more than 300% the productivity of grain and peanut pods.
