The Gerbera is an ornamental perennial herb, belonging to the Asteraceae family. Its cultivation, as well as the entire market for flowers and ornamental plants, is now in full expansion phase. The objective of this study was to evaluate the growth and quality Potted gerbera cultivar Red, according to sources and doses of potassium. The experiment was conducted in a greenhouse at UNESP/Botucatu. The experimental design was randomized blocks, using a 2x5 factorial arrangement, with two sources (potassium silicate and chloride) and five doses (0, 50, 100, 150 and 200 mg. L-1) 4 replications and 5 plants per plot. Weekly throughout the experimental period, assessments were made of the number of leaves (NL) and the diameter of the plant canopy (DP). at the end of the season and the reproductive cycle, at 42 and 60 days after acclimatization (DAA), respectively, were determined by leaf area (LA), mass (dry leaves (MSF), the dry mass of inflorescence (MSI) and total dry matter (TDM). at the point of marketing is that of open stamens, when the inflorescence had at least two rounds of open, releasing pollen, we determined the number of inflorescences (NI), the diameter of inflorescence (DI), the stem height (AH), the shank diameter (DH) and plant height (PH). Regardless of the doses, potassium silicate promoted greater diameter, leaf area, greater MSF, MST and increased stem height, characteristics that favor the sale of potted gerbera.

The objective of this work was to evaluate the agronomic performance and grain quality, especially the grain technological characteristics in the common bean genotypes, cultivated in winter-spring season. The experiment was carried out in Jaboticabal-SP, in a Rhodic Hapludox. The experimental design was a randomized block with 17 treatments (genotypes) with three replications. The plots had been composed for 17 carioca common bean group genotypes (Pérola, BRS Cometa, BRS Pontal, IPR Juriti, CNFC 10703, CNFC 10713, CNFC 10716, CNFC 10721, CNFC 10729, CNFC 10733, CNFC 10742, CNFC 10753, CNFC 10757, CNFC 10758, CNFC 10762, CNFC 10763 and CNFC 10813). BRS Pontal and CNFC 10716 showed simultaneously the higher number of per plant and grain yield. The technological characteristics more expressive was verified in CNFC 10703, CNFC 10713, CNFC 10758, CNFC 10813 and CNFC 10716 genotypes, principally about the protein content, cooking time and grain hydration capacity. The CNFC 10716 genotype detached as promissory, because their elevated agronomic performance and satisfactory technological characteristics.
