Uso de bioestimulante comercial para a produção de mudas de repolho

Cabbage is a vegetable of European origin cultivated in all regions of Brazil during the periods of the year. It is an herbaceous plant with an exotic flavor and a great alternative for use in the kitchen. It has a short cycle and a high production capacity, which indicates the need to adopt adequate management measures to guarantee the expected productivity. Among the management practices, correct fertilization is essential for the supply of essential nutrients and, currently, numerous biofertilizers products are marketed. Therefore, the aim of this work was to determine the effect of different doses of a commercial biofertilizer for cabbage seedling production. The experiment was conducted and conducted in an IFMG greenhouse - Campus Bambuí Olericulture Sector, in a completely randomized design with seven treatments and four replicas. The treatments consisted of different doses of bio-fertilizer applied to cabbage seeds (control - without biofertilizer; 1 ml /L-1; 1.5 1 ml /L-1, 2 1 ml / L-1, 2.5 1 ml / L-1, 3 1 ml /L-1 and 3, 5 1mL / L-1). Cabbage seeds of the Mammouth Red Rock cultivar were used, sown in pellets of 128 cells with commercial substrate. The following characteristics were evaluated: seedling height, number of leaves, stem diameter, green weight of the shoot, green weight of the root, length of the root, dry weight of the shoot and dry weight of the root. The data obtained were subjected to analysis of variance and regression using the statistical program SISVAR 5.0 (FERREIRA, 2011). The analyzes revealed significant differences between the different dosages for all the characteristics evaluated. For the green weight characteristic of the aerial part the best dosage was 3 ml / L and for the other characteristics the dosage of 3.5 ml / L was the one that promoted the best performance. cabbage seedlings production.
