| ABSTRACT Light is one of the factors that most affect crop growth and yield. However, the control of light intensity is difficult, because, under certain environmental conditions, light energy may exceed or limit the capacity of plants to use it. In this sense, the productive behavior of plant species in shaded environments needs to be known. This study aimed to evaluate the effect of different shaded environments with black shade nets [0 (full sun), 35 and 50%, and overlap 35 + 50% shading nets] on flowering, yield and quality of inflorescences of Heliconia psittacorum (cv. 'Golden Torch'). The shaded environments caused a reduction in the number of days for inflorescence emergence and in the cycle of H. psittacorum (cv. 'Golden Torch'). The yield and... |

| 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... |
