Seed coating is a process in which a thin and uniform polymer layer is deposited on the surface of a seed. The objective of this study was to evaluate the vigor of barley seed coated with a commercial polymer and various combinations of calcium, silicon and fungicide. In addition to a control with only the polymer coating, a total of 17 seed coating treatments were used in a completely randomized factorial design (18 treatments × 4 replicates per treatment). Calcium and silicon were applied at concentrations of 0, 25 or 50 g kg¹ of seed, and 0 or 3.0 mL of fungicide was applied. The means were compared using a Duncan test (P≤0.05). The results showed that a coating of polymer, fungicide, calcium and silicon did not affect the physiological... |

The practices and techniques used in irrigated rice to improve performance include optimal plant density and the best arrangement of the plants in an area. This study aims to evaluate the performance and plasticity in the yield and grain quality of three rice hybrids using different row spacing. The field experiments were conducted during the 2010/2011 season in rice crops in Capão do Leão, Viamão and Uruguaiana in the state of Rio Grande do Sul, Brazil. Three different sowing arrangements were evaluated, i.e., row spacing of 17 cm, 34 cm, and 17 cm alternated with 34 cm, which corresponded to densities of 40, 20 and 32 kg ha-1, respectively. The experimental design used was randomized blocks with subdivided plots replicated three times considering each... |
