Atributos químicos do solo e produtividade da cultura de soja em área de semeadura direta após calagem superficial

This study was carried out to evaluate the effects of surface application of lime rates on soil chemical attributes and soybean yield in a no-tillage system. It was installed a field experiment in a factorial 2×4, and the factors were: two types of lime (calcitic and dolomitic); four rates (0.0 - 0.5 - 1.0 and 1.5 t ha-1 of CaCO3), in a completely randomized blocks experimental design, with four replications. The experiment was located in Matupá, Mato Grosso State, Brazil, being the work developed between November 2006 and May 2007. The evaluations were chemical attributes in the soil layers (0,0-2,5 cm, 2,5-5,0 cm and 5,0-10,0 cm), and the productive characteristics of soybean. Application of lime increased the soil pH (CaCl 2), the exchangeable Ca and Mg, the effective CEC and the base saturation only in the soil surface layer. The two limes were different only for Ca and Mg values in the first layer of soil, and only for the Mg values in the layer of 2,5-5,0 cm. The surface liming in no-tillage system did not change soybean yield.

Caracterização de requeijão cremoso potencialmente prebiótico pela adição de inulina e proteína de soja

Requeijão is a typical Brazilian cheese and exhibits a significant consumption in the domestic market and presents high potential for functional foods. In this study the physicochemical characterization of requeijão cheese added of dairy cream, hydrogenated vegetal fat, soy protein isolate and inulin was carried out. For the requeijão cheese making it was used: Lactic mass, sodium chloride, melting salt, starch, whey protein concentrate, xanthan gum, nisin and water. Dairy cream (2.0; 4.0 and 6.0%), hydrogenated vegetable fat (6.0; 8.0 and 10.0%), soy protein isolate - SPI (0.5; 1.0 and 1.5%) and inulin (3.8; 5.05 and 6.3%) were added, according to the trial. The formulated products presented 6.26 to 6.38 of pH value, 0.24 to 0.39% of acidity, 7.29 to 10.04% of protein, 1.62 to 1.77% of ashes, 12.5 to 21.3% of fat, 39.8 to 66.1% of fat dry matter and 28.63 to 35.56% of total solids. The developed requeijão cheeses added of soy protein isolate and inulin are feasible alternatives for healthy foods and potentially prebiotics.

Influência da cobertura de aveia-preta e milheto sobre comunidade de plantas daninhas e produção de soja

The success in weed control by using straw depends on the management time, straw quality and quantity. The objective of this research was to evaluate the suppressor effect of black-oats and millet straw cover on the incidence of weeds and on the productivity of the soybean crop. The experiment was carried out during the years 2006 and 2007, in an area from the Farm of Education, Research and Production of FCAV-UNESP, Jaboticabal Campus, in a completely randomized block design, with four replications. Treatments consisted of different types of black oats and pearl millet straw management before soybean seeding (without management, obtained by machine cut, desiccated using glyphosate desiccation and with paraquat) and different periods of straw deposition (0, 15, 30 e 60 days before soybean seeding). The weed population and the characteristics of soybean growth and production were evaluated. The deposition of black oats and pearl millet straw provided reductions in weed density and dry mass, and this effect was more effective when the deposition occurred until 15 days prior to soybean seeding. The suppressor effect of black oats straw was more pronounced than that of pearl millet straw, regardless of the drying method, although the millet had a greater dry matter production. No significant differences were found between the drying methods and the straw effectiveness.
