| description | Soybean is a crop of great importance for Brazil, and knowledge of their nutritional status allowsproduction and high quality products. Thus, the present work aimed to evaluate the culture of thesoybean cv. BRSMG 68 (Vencedora), submitted to macronutrients omission on the development,nutritional status and the visual symptomatology of nutrient deficiency. The design used wascompletely randomized, with seven treatments that corresponded to the complete (macro andmicronutrients) solution and the individual omission of N, P, K, Ca, Mg and S. The treatments wereapplied two weeks after the emergency of the soybean. The nutrient solution was constantlyoxygenated and replaced weekly, and the pH monitored daily remained around 5. After six weeksof application of the treatments, the height of the plants, number of leaves, stem diameter wasevaluated, matter dry accumulated in the roots, it leaves aerial and the nutritional state and thecharacterization of the visual symptoms. The macronutrient deficiency promoted a decreasein production of root and shoot dry mass of soybean cultivar BRSMG 68 (Vencedora) in nutrientsolution, for the full treatment. The most limiting nutrient for dry matter production of soybeancompared to complete treatment were N, S and K, with decreases of 90, 76 and 73%, respectively.Individual omissions resulted in morphological changes, which were translated by characteristicvisual symptoms of nutritional deficiency of the respective nutrient. |

A soja é uma cultura de grande importância para o Brasil, e o conhecimento de seu estadonutricional adequado possibilita produções elevadas e produtos de qualidade. Deste modo, opresente trabalho objetivou avaliar plantas de soja cv. BRSMG 68 (Vencedora), submetidas àomissão de macronutrientes no desenvolvimento, estado nutricional e a sintomatologia visual dedeficiência. O delineamento experimental foi inteiramente casualizado, com sete tratamentos quecorresponderam à solução nutritiva de Hoagland completa (macro e micronutrientes) e a omissãoindividual de N, P, K, Ca, Mg e S. Os tratamentos foram aplicados duas semanas após a emergênciada soja. A solução nutritiva foi oxigenada constantemente e substituída semanalmente, tendo opH monitorado diariamente mantendo-se ao redor de 5. Após seis semanas da aplicação dostratamentos, avaliou-se a altura das plantas, o número de folhas, o diâmetro de caule, a matériaseca acumulada nas raízes, parte aérea e o estado nutricional e a caracterização dos sintomasvisuais. A deficiência de macronutrientes promoveu decréscimo da produção de matéria secade raiz e da parte aérea da soja cultivar BRSMG 68 (Vencedora) em solução nutritiva, em relaçãoao tratamento completo. Os nutrientes mais limitantes a produção de matéria seca das plantasde soja comparado ao tratamento completo foram N, S e K, com decréscimos de 90, 76 e 73%,respectivamente. As omissões individuais resultaram em alterações morfológicas, que foramtraduzidas por sintomas visuais característicos da deficiência nutricional do respectivo nutriente. 2010-12-01 2022-03-21T20:06:55Z 2022-03-21T20:06:55Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://comunicatascientiae.com.br/comunicata/article/view/48 10.14295/cs.v1i2.48 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/77496 por https://comunicatascientiae.com.br/comunicata/article/view/48/35 application/pdf Federal University of Piauí Comunicata Scientiae; Vol. 1 No. 2 (2010); 114 Comunicata Scientiae; v. 1 n. 2 (2010); 114 2177-5133 2176-9079 |
