Soil fertility, nutrition and yield of maize and barley with gypsum application on soil surface in no-till

Annual crop yield and nutrition have shown differentiated responses to modifications in soil chemical properties brought about by gypsum application. The aim of this study was to evaluate the effect of gypsum application rates on the chemical properties of a Latossolo Bruno (Clayey Oxisol), as well as on the nutrition and yield of a maize-barley succession under no-till. The experiment was set up in November 2009 in Guarapuava, Parana, Brazil, applying gypsum rates of 0.0, 1.5, 3.0, 4.5, and 6.0 Mg ha-1 to the soil surface upon sowing maize, with crop succession of barley. Gypsum application decreased the levels of Al3+ and Mg2+ in the 0.0-0.1 m layer and increased soil pH in the layers from 0.2-0.6 m depth. Gypsum application has increased the levels of Ca2+ in all soil layers up to 0.6 m, and the levels of S-SO4(2-) up to 0.8 m. In both crops, the leaf concentrations of Ca and S were increased while Mg concentrations have decreased as a function of gypsum rates. There was also an effect of gypsum rates on grain yield, with a quadratic response of maize and a linear increase for barley. Yield increases were up to 11 and 12 % in relation to control for the maximum technical efficiency (MTE) rates of 3.8 and 6.0 Mg ha-1 of gypsum, respectively. Gypsum application improved soil fertility in the profile, especially in the subsurface, as well as plant nutrition, increasing the yields of maize and barley.

Hordein polypeptide patterns in relation to malting quality in Brazilian barley varieties

Since there is evidence that malting quality is related to the storage protein (hordein) fraction, in the present work the hordein polypeptide patterns from 13 barley (Hordeum vulgare L.) varieties of different malting quality were analysed in order to explore the feasibility of using hordein electrophoresis to assist in the selection of malting barleys. The formation of clusters separating the varieties with higher malting quality from the others with lower quality suggests that there is a relationship between the general hordein polypeptide pattern and malting quality in the varieties analysed. By the Sperman's correlation test three hordein bands correlated negatively with malting quality in the germplasm studied.

Atividade de peroxidase e polifenoloxidase na resistência do feijão à antracnose

O objetivo deste trabalho foi avaliar a influência das enzimas peroxidase e polifenoloxidase na resistência à antracnose de quatro cultivares de feijão. Plântulas de feijão foram pulverizadas com ácido salicílico e com a raça delta de Colletotrichum lindemuthianum (fungo indutor) e submetidas à inoculação do patótipo virulento 33/95 de C. lindemuthianum três dias após a aplicação do fungo indutor e do ácido salicílico. Essas plantas foram avaliadas quanto à atividade enzimática e teores de fenóis, três dias após a aplicação do fungo indutor e cinco dias após a inoculação do patótipo virulento. Acréscimos nas atividades dessas enzimas foram maiores nos tratamentos com ácido salicílico e fungo indutor em todas as cultivares. Maiores estímulos nas atividades enzimáticas foram observados nas cultivares com maior resistência à doença. Constatou-se o aparecimento de uma isoperoxidase nos tratamentos com fungo indutor, ácido salicílico, após inoculação do patótipo virulento, e na testemunha, nas cultivares AB 136, Rio Tibagi e Macanudo. Houve correlação positiva entre as atividades da peroxidase e da polifenoloxidase, os teores de compostos fenólicos e a resistência à antracnose.
