Produção de mudas de berinjela em diferentes tipos de substratos alternativos.

Abstract

The culture of eggplant (Solanum melongena L.) is very rustic and tolerant to some diseases, it is a perennial plant, but it can be cultivated annually. Eggplant being seen being implanted through seedlings, therefore, for a good production it is necessary to use quality seedlings. The main concern in the production of seedlings is the substrate used. Thus, this work aimed to evaluate the production of eggplant seedlings under different types of alternative substrates. The experiment was carried out in a greenhouse at the Center for Science and Agri-food Technology, Federal University of Campina Grande (CCTA-UFCG), Campus Pombal, PB, from July to September 2020, using the outline scheme in blocks of eight by four (8x4), totaling thirty-two plants. The treatments were the substrates called T1 (control, soil only); T2 (soil + cattle manure); T3 (soil + coconut fiber); T4 (soil + sugarcane bagasse), the proportion used was 2: 1 in all treatments. A polypropylene bag 15 cm wide by 23 cm high was used. Stem size, stem diameter, root size, fresh weight of both the aerial part and the root and dry mass of the aerial part and the root were evaluated. The best results were observed in seedlings grown with bovine manure and in isolation, the treatments of coconut fiber and sugarcane bagasse for better results when compared to the others. Therefore, it is concluded that the substrate that provides better mute development and better performance does not grow from eggplant or manure.
