Produtividade, teor foliar e exportação de nutrientes em cultivares de batata

The right choose of the cultivar influences greatly the potato yield. It is very important to know its agronomic behavior in the region where it is planted, as well its nutritional status, in order to supply the best package in the fertilization operations. In this work the tuber yield, the nutritional status of plants and the exportation of nutrients were studied in eighteen potato cultivars. A randomized blocks experimental design, with four replicates, was used. Mondial showed the highest total and commercial yields. The nutrient concentrations in fourth leaf of potato plant followed the decreasing order: N>K>Ca>P>Mg>B>Zn. The exportation of nutrients by the tubers followed the decreasing order: K>N>P>Mg>Ca. B and Zn had different behavior according the cultivars.

Batata cv Pirassu como matéria prima industrial

The starch market has been growing and improving in recent years, leading to a search for products with specific characteristics that meet the industrial requirements. This work aimed to evaluate the centesimal composition of potato tubers cv Pirassu and its industrial potential. The potato cv Pirassu was cultivated in Pouso Alegre, mountainous region south of Minas Gerais state, with planting season in August and harvest season in November, 2011. The tubers were analyzed for color, pulp and centesimal composition. The starch extract was analyzed for centesimal composition, phosphorus content, apparent amylose, pasting properties and thermal properties. The results showed that the content of dry matter, total soluble sugar and starch of tubers, are compatible for processing for potato chips. The starch of this cultivate showed important viscosity characteristics for food industry such as: heat resistance and friction, good final viscosity and low granular organization.
