| ABSTRACT This study aimed to evaluate the effect of nitrogen (N) and potassium (K) fertilization in yield and contents of macronutrients in heliconia plants (Heliconia psittacorum x Heliconia spathocircinata Aristeguieta) cv. Golden Torch. The experiment was set in a randomized block design, in a 4 x 4 factorial, corresponding to N doses (0, 120, 180 and 240 g of N hole-1) and K doses (0, 120, 180 and 240 g of K2O hole-1) with four replicates and five rhizomes per plot, under field conditions. After one year of cultivation, yield (number of flower stems per square meter) and the leaf contents of N, P, K, Ca, Mg and S were determined. The applied N doses did not influence either yield or the leaf contents of the evaluated macronutrients. K fertilization... |

| ABSTRACT Irrigated fruit crops have an important role in the economic and social aspects in the region of the Sub-middle São Francisco River Valley. Thus, the aim of this study was to evaluate soil salinity and the productive aspects of the mango crop, cv. Tommy Atkins, fertigated with doses of potassium chloride (KCl) and potassium sulfate (K2SO4) during two crop cycles (from January to March 2014 and from January to March 2015). The experiment was carried out in a strip-split-plot design and five potassium doses (50, 75, 100, 125 and 150% of the recommended dose) as plots and two potassium sources (KCl and K2SO4) as subplots, with four replicates. Soil electrical conductivity (EC), exchangeable sodium (Na+) and potassium (K+) contents and pH were... |
