O trabalho foi desenvolvido com o objetivo de avaliar as alterações nos teores e acúmulo de nutrientes da parte aérea da batateira, em função de doses de boro em amostras de um Latossolo Vermelho (LV) e de um Cambissolo (CX). O delineamento experimental foi em blocos casualizados (DBC) em esquema fatorial 4 x 2, constituído de quatro doses de B (0,0; 0,75; 1,50 e 3,0 mg dm-3) e duas cultivares de batata (Asterix e Monalisa), 2 tipos de solos (Latossolo e Cambissolo) e três repetições. Foram avaliados os teores de N, P, P Ca, Mg, S, B, Cu,Fe, Mn, e Zn nas folhas e acúmulo na parte aérea de cada cultivar. Os tratamentos de forma individual e/ou em interação influenciaram tanto os teores como o acúmulo dos nutrientes na batateira. Dependendo do tipo de solo e cultivar, houve influencia sobre os teores de Mg, P e Mn nas folhas e o acúmulo de N, P, K, Ca, Mg, S, B, Cu, Fe, Mn e Zn na parte aérea. As doses de B, independentemente das cultivares, elevaram o teor e acúmulo de B e reduziram os de S, Cu, Fe e Zn, conforme o tipo de solo. Promoveram também, conforme o tipo de solo, aumento nos teores K, B e Fe e acúmulo de S na cultivar Asterix e, aumento nos teores de P e B, acúmulo de N, Cu, e Zn e redução nos teores de K, Ca, Mn e Fe na cultivar Monalisa.
The study was carried out to evaluate the nutrient content alterations of the potato shoots submitted to boron rates. The experiment had a randomized blocks outline in 4 x 3 factorial arrangement, using four boron rates (0.0, 0.75; 1.50 and 3.0 mg dm-3) and two potato cultivars (Asterix and Monalisa) with three replicates. Two soil types were used, Latosol and Cambisol. Leaf and shoots N, P, K, Ca, Mg, S, Fe, Cu, Mn, Zn and B contents of each cultivar were evaluated. The treatments as in individual or in interaction form influenced the potatoes nutrient content and its nutrient accumulation on the plant. Depending on the soil type Mg, P and Mn content were influenced on the leaves and the N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn accumulation content on the aerial part. Depending on soil type and cultivar there was influence on the Mg, P and Mn content on the leaves and accumulation of the N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn in aerial part. The B rates independely from cultivars elevated the boron content and accumulation and reduced the S, Cu, Fe and Zn contents according to soil type. They also promoted according to soil type, increases on K, B and Fe and S accumulation on Asterix cultivar and, increases on and P and B content, and accumulation of N, Cu, and Zn and content reduction on K, Ca, Mn and Fe, on Monalisa cultivar.
