Abstract: Phosphorus (P) is one of the main nutrients capable of increasing yields of tropical grasses. The definition of adequate P fertilizer rates can contribute to improving forage production of pastures. However, the efficiency in the response of different genotypes of Urochloa mosambicensis (Hack.) Dandy (Bushveld herringbone grass) to P fertilizer rates is not known. This study aimed to quantify the response of U. mosambicensis genotypes to P fertilizer levels and classify the genotypes as to efficiency and responsiveness. The experiment was carried out in pots, under controlled conditions, in a completely randomized design, in a 2 x 9 factorial with five replications. The factors consisted of equivalent P rates of 10 and 90 kg ha-1 of P2O5 (triple superphosphate) and eight genotypes of U. mosambicensis (UmCO-1 (2), UmCO-2 (2), UmCO-4 (1), UmCO-8 (1), UmCO-11 (2), UmCO-12 (2), UmCO-13 (2) and UmCO-14 (2)), in addition to a control, Urochloa brizantha syn. Brachiaria brizantha cv. BRS Piatã. Each experimental unit consisted of one pot. Biometric attributes and dry mass yield were evaluated over four cutting cycles. There was no effect of the P fertilization x genotypes interaction for the variables evaluated. However, the highest fertilizer rate increased dry mass yield and tiller population density in all genotypes and cuttings evaluated. The genotype UmCO-4 (1) and the cultivar BRS Piatã proved to be responsive to and efficient in P use. The highest P rate promoted greatest production of dry mass and greatest number of tillers in all genotypes of U. mosambicensis.
Resumo: O fósforo (P) é um dos principais nutrientes capazes de aumentar a produtividade de gramíneas tropicais. A definição de doses de P pode contribuir para aumentar a produção de forragem em pastagens cultivadas. Todavia não se conhece a eficiência na resposta de diferentes genótipos de capim-corrente (Urochloa mosambicensis (Hack.) Dandy) a doses de P. Este estudo objetivou quantificar a resposta de genótipos de capim-corrente a níveis de adubação com P e classificá-los segundo a sua eficiência e responsividade. O experimento foi conduzido em vasos, em condições controladas, no delineamento inteiramente casualizado, num esquema fatorial 2 x 9, com cinco repetições. Os fatores consistiram de doses equivalentes de P de 10 e 90 kg ha-1 de P2O5 (superfosfato triplo) e oito genótipos de U. mosambicensis (UmCO1 (2), UmCO-2 (2), UmCO-4 (1), UmCO-8 (1), UmCO-11 (2), UmCO-12 (2), UmCO-13 (2) e UmCO-14 (2)), além da testemunha Urochloa brizantha syn. Brachiaria brizantha cv. BRS Piatã. Cada unidade experimental foi constituída de um vaso. Foram avaliados atributos biométricos e rendimento de massa seca ao longo de quatro ciclos de corte. Não houve efeito da interação entre adubação x genótipos para as variáveis avaliadas. Entretanto, a maior dose do fertilizante incrementou o rendimento de massa seca e densidade populacional de perfilhos em todos os genótipos e cortes avaliados. O genótipo UmCO-4 (1) e a cultivar BRS Piatã revelaram-se responsivos e eficientes no uso de P. A maior dose de P promoveu maior produção de massa seca e maior número de perfilhos em todos os genótipos de U. mosambicensis.

Strawberry is a highly perishable fruit due to postharvest pathological problems, mainly caused by Botrytis cinerea fungus. Thus, edible coatings can be a technological alternative to chemical additives in strawberry preservation, because coatings from natural sources have been considered an environmentally friendly technology, used to preserve and extend the postharvest shelf life of fruits. Therefore, the aim of this study was to evaluate the capacity of two edible coatings (sodium alginate and carboxymethyl cellulose) to keep the physicochemical and microbial quality and extend shelf life of strawberries. The produced coat was obtained from the spreading of film-forming solution on glass petri dishes and strawberries were immersed in the coating solution and stored at refrigeration temperature (2.0?4.5°C). Thermogravimetric analysis, film thickness and weight loss percentage of the coated and control samples were performed. The films exhibited thickness from 0.015 to 0.060 mm. Thermogravimetric analysis showed similar decomposition behavior for the films produced. In addition, the films showed suitable thermic stability. Weight loss percentage were not significantly diferente (p>0.05) in coated strawberries compared to the control. Edible coating prevented Botrytis sp. injuries when stored up to 5 days at refrigeration temperature. Therefore, strawberry coated presented higher microbial quality characteristics than control and it can be a potential alternative to fruit industry. Further studies should be performed to optimize the composition of films in order to preserve also thephysicochemical quality of strawberries.
