Abstract

Growth, development and the productivity of potato are related to the fertilization of soil and spacing. Dose calibration is required for each type of soil and cultivar. Current analysis evaluates the influence of different doses of fertilizers and spacing between plants in biometric attributes and productivity of potato cultivar Asterix. Experimental design was completely randomized, 2 x 4 scheme, with two spacings (0.2 and 0.4 m) and four doses of mineral fertilizers NPK 7-28-14 (0, 500, 1000 and 1500 kg ha-1), with a total of 8 treatments and 3 replications. Number of leaves and stems, height of plants, number of tubercles per plant, mean mass of tubercles and productivity were assessed. Results showed that there was interaction between spacing between plants and fertilization doses applied with great productivity for spacing 0.2 m and 1500 kg ha-1 fertilizer.
