Uso da cinza vegetal na produção de Beta ulgaris esculenta

Abstract

Nowadays, a lot of waste is generated and ends up not having a correct destination. However, many of these substrates can be used as fertilizers, as is the case with the forest biomass residue used in the experiment. This ash has large amounts of chemical elements that serve as nutrients for the soil and, consequently, for plants, as well as for soil acidity correction. To increase the productivity of vegetables, soil with large nutritional amounts is required. Thus, this work intended to evaluate the beet production under different doses of vegetable ash. The soil was collected at a depth of 0 - 20 cm, mixed with the treatments and placed in pots. Six treatments were used, with seven repetitions each. The treatments of vegetable ash doses that were administrated are: 0; 7; 14; 21; 28 and 35 g.dm⁻³. The physiological parameters analyzed were root weight, root diameter, number of leaves, leaf area of the plants, fresh and dry weight of the root and aerial and pH evaluation. Through this work it can be observed that the beet plants corresponded significantly to the fertilization with ash, so that doses up to 30 g.dm-3 promoted considerable increases in the evaluated characteristics. In addition to the properties of the plants, the ash also provided an improvement in the chemical qualities of the pH, CTC, SB, macronutrients and micronutrients, serving as an alternative to beet production in a sustainable way.
