Produção de mudas de rúcula (Eruca sativa L.) em diferentes substratos, tamanhos de células e densidades de semeadura

Abstract

The objective of this work was to evaluate the production of arugula (Eruca sativa L.) seedlings in different substrates, call size and sowing density. The study was conducted at Pampa Federal University - Campus Itaqui / RS, in a greenhouse, conducted in two seasons in 2017 and 2018. We used a "Larga" leaf cultivar in a randomized experimental design in a 2x3x4 trifactorial arrangement (substrate x cell size x plant density). For the second season, the design was in a 3x4 bifactorial arrangement (tray size x sowing density). Mecplant® commercial substrate and a compound consisting of Mecplant® commercial substrate + soil were used. Also used trays were used three types of trays which were 72, 128 and 200 cells and volume of 50, 25,09 and 12,39 cm³, respectively. In addition, four plant densities were used, corresponding to one, three, six and nine plants per cell. Evaluations were made for root and shoot length, fresh root and shoot mass, dry root and shoot mass and number of leaves. There was significant interaction between the evaluated factors, indicating that the substrate, sowing density and cell size influence the analyzed variables in the production of arugula seedlings of the cultivar "Folha Larga". The production of arugula cultivar “Folha Larga” was influenced by substrate type, cell size and seed density. . The use of comercial substrate, trays of 72 cells and with density o fone plant presented the highest values for all evaluated parameters.
