Abstract: Aiming to study the effect of the liming on the growth and nutrition of sweet passion fruit plants, two experiments were carried out in the greenhouse of the Agriculture Department of the Federal University of Lavras (UFLA). The statistical design used was randomized blocks in a factorial scheme (2x4) + 2, with four replications. The treatments involved two soil classes (Dystrophic Red-Yellow Latosol - LVAd and Dystrophic Red Latosol - LVd), four base saturation leveis (40%, 60%, 80% and 100%) and two more additional treatments, LVAd without liming and LVd without liming. The fírst experiment was carried out with seedlings (originated from seeds) and the second with cuttings. The experimental plot was constituted of four vases in the fírst experiment and two vases in the second. After 150 days, the stem length, number ofleaves, dry matter ofshoots and roots, the roots/shoots ratio, macro and micronutrients contents in the shoots dry matter and P, Ca and Mg in the roots dry matter were evaluated. It was concluded that in both experiments the largest growth happened in the LVd and the sweet passion fruit tolerates soils with low base saturation leveis. In the fírst experiment, with seedlings, the increase ofbase saturation leveis reduced vegetative growth ofplants in the LVd but had no influence in the LVAd. For both soil classes, this increase did not influence the contents ofN, P and K, increased the contents ofCa, Mg and S and reduced the contents of Cu, Mn and Zn in the shoots dry matter. As for the content of B the increase of base saturation leveis caused an increase of B in shoots dry matter in the LVd and did not change these contents in the LVAd. For the second experiment, with cuttings, it was concluded that the increase of base saturation leveis did not influence the vegetative growth and increased the contents ofP, Mg and S in the shoots dry matter, independently ofthe soil class. For Ca it was observed an increase in shoots dry matter ofplants cultivated in the LVd and no response in the LVAd. K contents in shoots dry matter decreased in the LVd and had no response in the LVAd. The increase in base saturation leveis reduced the contents of B, Cu, Mn and Zn in the shoots dry matter ofsweet passion fruit plants in both soil classes.
