Resumo: | Minituber production is an important step to obtain high-quality seed potatoes. This production is carried out in a greenhouse using a large volume of commercial substrate acquired in specialized trade. An alternative to reduce the volume of substrate purchased for each production of minitubers would be to reuse it, which would be a way to optimize its use. The objective of this study was to evaluate the efficiency of reused substrates in the minituber production. The experiment was conducted in Tapira-MG with the Atlantic potato cultivar. The experimental design was a randomized block with six treatments and four replications, where each plot was represented by a box (0.15 x 0.4 x 0.5m: height, width, and length, respectively) containing substrates. Treatments consisted of formulation 04-14-08 rates (0, 25, 50, 75, and 100 g box-1) added to reused substrate and a control consisting of a new virgin substrate. At 45 days after transplanting, the following characteristics were evaluated: stem size (cm), and quantities of fresh and dry matter of aerial part of plants. Harvesting was performed manually, counting, and calculating the yield of tubers according to class. The reuse substrate with enriched nutrient regardless of the rate, when compared to the use of a new virgin substrate, did not interfere in potato plant development and in the total productivity of minitubers of classes I, II, III, and IV. This can be a feasible alternative for optimizing the use of the virgin substrate. The rate of 25 g box-1 of 4-14-8 is sufficient to provide the needs of potato in nutrients, ensuring high productivity. |

Esta produção é realizada em estufa e utiliza substrato, o qual contribui para o aumento do custo final de produção devido ao alto volume utilizado. Uma alternativa para reduzir tal custo seria a reutilização do substrato. Neste sentido, objetivou-se avaliar a eficiência de substratos reutilizados acrescidos de doses crescentes de adubação e, compará-los com substrato novo, quanto à produção de minitubérculos em telado. O experimento foi conduzido no município de Tapira-MG, com a cultivar Atlantic. O delineamento experimental foi o de blocos casualizados com seis tratamentos e quatro repetições, onde cada parcela foi representada por uma caixa. Os tratamentos foram constituídos por doses do formulado 04-14-08 (0, 25, 50, 75 e 100 g caixa-1) adicionadas ao substrato reutilizado e uma testemunha com substrato novo. Aos 45 dias após o transplantio foram avaliadas as características: tamanho de haste (cm), matéria fresca e matéria seca da parte aérea. A colheita foi realizada manualmente e procedeu a contagem e a produtividade de tubérculos, em classes. O substrato reutilizado enriquecidos com nutrientes, independentemente da dose, quando comparado ao uso de um novo substrato, não interfere no desenvolvimento da planta de batata e na produtividade total dos minitubers das classes I, II, III e IV. Esta pode ser uma alternativa viável para produtores com custos mais baixos e exploração deste recurso indispensável na formação de batatas de semente. A taxa de 25 g box-1 de 4-14-8 é suficiente para atender às necessidades de batata em nutrientes, garantindo alta produtividade.EDUFU2020-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/5356810.14393/BJ-v36n0a2020-53568Bioscience Journal ; Vol. 36 (2020): Supplement1; 183-191Bioscience Journal ; v. 36 (2020): Supplement1; 183-1911981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/53568/31202Brazil; Contemporary Copyright (c) 2020 Ronei França de Almeida, Roberta Camargos de Oliveira, Alexandre Igor de Azevedo Pereira, Regina Maria Quintão Lana, José Magno Queiroz Luzhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAlmeida, Ronei França de Oliveira, Roberta Camargos de Pereira, Alexandre Igor de Azevedo Lana, Regina Maria Quintão Luz, José Magno Queiroz 2022-05-26T17:48:04Zoai:ojs.www.seer.ufu.br:article/53568Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-05-26T17:48:04Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
