Resumo: | The Physalis angulata L. species has attracted interest due to the production of compounds with pharmacological activity and its potential for fruiticulture. Given that it is a fast-growing and highly productive species, determining the most adequate nitrogen (N) doses could contribute to higher crop yields. This study aimed at assessing the influence of N concentrations, in a hydroponic system, on the growth and production of P. angulata, as well as determining the critical N level in leaves. The experiment was conducted in individual pots with nutrient solutions, applying a completely randomized design and twelve replications, using five N doses (0 mg L-1, 56 mg L-1, 112 mg L-1, 168 mg L-1 and 224 mg L-1). Growth and production indices, amount of total N on leaves and stems and critical N levels were assessed. The increase of N doses in the nutrient solution influenced plant growth and fruit production, as well as the accumulation of total N in the leaves and stems. Based on the maximum economic yield, a dose of 162 mg L-1 of N is recommended for hydroponics, which provided a fruit yield of 7.27 g m-2 and critical total N level in leaves of 51.98 g kg-1. |

Por apresentar crescimento rápido e grande produtividade, a definição de doses de nitrogênio (N) mais adequadas pode contribuir para maiores rendimentos da cultura. Objetivou-se avaliar a influência de concentrações de N, em sistema hidropônico, sobre o crescimento e produção de plantas de P. angulata, bem como determinar o nível crítico de N nas folhas. O experimento foi conduzido em vasos individuais com soluções nutritivas, em delineamento inteiramente casualizado com doze repetições, utilizando-se cinco doses de N (0 mg L-1, 56 mg L-1, 112 mg L-1, 168 mg L-1 e 224 mg L-1). Foram avaliados os índices de crescimento e produção, a quantificação do N total nas folhas e caules e o nível crítico de N. O aumento das doses de N na solução nutritiva influenciou o crescimento das plantas e a produção de frutos, bem como o acúmulo de N total nas folhas e caules. Com base na máxima produtividade econômica, recomenda-se para o cultivo hidropônico a dose de 162 mg L-1 de N, que proporcionou produtividade dos frutos de 7,27 g m-2 e nível crítico de N total nas folhas de 51,98 g kg-1.Escola de Agronomia - Universidade Federal de Goiás2017-05-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/44652Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 47, n. 2, Apr./Jun. 2017; 145-151Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 47, n. 2, abr./jun. 2017; 145-151Pesquisa Agropecuária Tropical; v. 47, n. 2, abr./jun. 2017; 145-1511983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/44652/23146Copyright (c) 2017 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessLeite, Romeu da SilvaTanan, Tamara Torresdo Nascimento, Marilza Nevesde Oliveira, Lenaldo MunizAbreu, Pedro Alcantara da Silva2020-07-13T18:33:38Zoai:ojs.revistas.ufg.br:article/44652Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:16.154890Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
