Abstract

The present work aimed to evaluate the effects of nitrogenous and potassic fertilization on nutritional state and dry matter of yellow passion fruit seedlings, cultivated in Red Latosol (Haplustox). Experimental design was randomized with 16 treatments and 3 replications, 4 x 4 factorial scheme design, whereas 4 doses of nitrogen were used (zero, 75, 150, 300 and 600 mg N dm^-3) and 4 doses of potassium (zero, 75, 150, and 300 mg K dm^-3). Fertilizers were divided into four parcels. The experimental unit consisted of pots (3.3 L). Following a period of 84 days after seeds germination, dry matter production, macro and micronutrient contents on vegetal tissue were evaluated. The highest dry matter production was related to 44 g of N kg^-1 and 18 g of K kg^-1 contents on aerial part. The highest dry matter production was related to 33 g of N kg^{-1and 34 g of K kg-1 contents on roots, which corresponds to the application near 340 mg of N dm-3 and 300 mg of K dm-3.}
