Crescimento inicial de duas cultivares de salsa (Petroselinum crispum) em diferentes substratos

Abstract

The consumption of vegetables is increasingly being encouraged, as they are important foods for the composition of healthy diets for humans. In addition, consumers are looking for products that, in addition to food characteristics, have some functional characteristics, thinking about improving their quality of life. Parsley or parsley (Petroselinum crispum) leafy vegetable plant, belonging to the Apiaceae family, widely used as a seasoning, in which its leaves are implemented dry or in natura, is a culture rich in medicinal substances that can prevent some diseases. They are widely grown on small farms and stand out as an important alternative for family farming. Studies related to parsley aim to improve the characteristics presented by the plants, generating good productive results, even when placed in environments different from what would be considered ideal. Due to this, the objective of the present work was to evaluate the growth and initial development of the parsley culture, Smooth and Graúda variety in different substrates in order to indicate the substrate that provides better production. The plant material used was the culture of parsley, Salsa Lisa and Salsa Graúda, the seeds were sown at 1.0 cm deep in the vegetable soil substrate, in a styrofoam tray. The harvest was done 35 days after sowing (DAS). The experiment was carried out in a completely randomized design (DIC), with treatments arranged in a 2 x 4 factorial scheme, with two species of Parsley (Lisa and Graúda) and four types of substrates. The treatments were: T1– rice husks + sand (3:1); T2 – sand + vermiculite (3:1); T3 – vegetable soil and T4 – buriti wood. Each treatment consisted of four repetitions, totaling 32 experimental units. The following variables were evaluated: stem diameter (DC), plant height (AP) number of leaves (NF), fresh and dry matter mass (MMFS). Parsley plants (Petroselinum crispum) in their initial development, when produced in buriti wood substrate, obtained better responses in relation to the evaluated characteristics, thus being considered the best substrate composition for the growth and development of the culture.
