| This study evaluated the morphological development of two populations of tough lovegrass during 120 days of continuous growth (Experiment I), and the regrowth of one population under the combination of cutting height (5 cm and 10 cm) and phenological stage at the first cutting (vegetative and beginning of flowering; Experiment II). In Experiment I, plants were harvested at 30, 60, 90 and 120 days of growth; in Experiment II, three cuttings were carried out at every 30 days, and the plants were harvested four weeks after the previous one. In Experiment I, the populations did not differ for morphological development, showing a linear increase in height and tiller number, and a quadratic trend for root and shoot dry matter (DM). At 120 days of growth, plants... |

| Abstract The aim of this study was to evaluate the effect of different doses of organic fertilization with doses of lithothanmium and vinasse on the initial growth of sugarcane cv. RB 86-7515. The study was carried out in the experimental area of the School of Agronomy, of Universidade Federal de Goiás, Brazil. A completely randomized experimental design was carried out to analyze data with three replicates, in a 5 x 5 x 2 factorial scheme. Plants were cultivated in containers of 200 liters. Treatments correspond to five vinasse doses (0, 165, 330, 495 and 660 m3.h-1) and five doses of lithothanmium (0, 100, 200, 300 and 400 kg.ha-1) and sugarcane cultivation under irrigated and rainfed conditions. Irrigation was carried out using a drip emitter system... |

| The aim of this study was to clarify the relationship between soybean leaf/plant age and the susceptibility to infection by Phakopsora pachyrhizi. Two studies were conducted in the greenhouse during the 2009/2010 season using the BRS 232 cultivar. The experimental design for Study 1 was fully randomized in a 2 x 3 factorial arrangement (phenological stage x age of the 4th, 5th and 6th trifoliate at the time of inoculation), and in Study 2, the experimental design was fully randomized with five treatments (T) and four replicates. The variables assessed were disease severity, number of lesions, uredinia per lesion, and viable spores. In Study 1, it was observed that disease severity was lower when the plant was in the growth stage V6 (11.4%), compared to the... |
