Influência de adubos orgânicos no desenvolvimento de plantas juvenis de banananeira (Musa acuminata cv. Grand Naine)

The banana crop has a huge social and economic impact for Brazil, where increases in economic income, motivated by better prices, and the expansion of the consumer market are strong factors for modernization and improvement of cultivation techniques. The study aimed to evaluate the effects of organic fertilizers on the development of juvenile plants of banana trees of the Cavendish Group, species Musa acuminata, variety Grand Naine. The experimental design used was randomized blocks, with 4 treatments, consisting of the fertilization of planting pit with dry bird bed, dry bird bed with shaving, liquid manure of quail and without fertilization, with 3 replications and considering 3 plants as an experimental unit. The experimental units were interspersed between each other by two plants to make up surrounds. The experimental units were interspersed between each other by two plants to make up surrounds. After 130 days, biometric parameters of height, neck diameter, number of shoots and leaf area were evaluated, in addition to the determination of fresh and dry shoot biomass, fresh biomass and rhizome drought, and then submitted to variance analysis and regression analysis followed by the Scott-Knott test, for separation of means. The results show that cloned banana seedlings Musa acuminata cv. Grand Naine responded positively to organic fertilization as a fertilization technology, where liquid quail manure had the best performance in all biometric parameters evaluated, compared to other treatments, in the development of juvenile seedlings.
