Resumo: | Potassium (K) deficiency has a direct impact on the productive performance of soybean (Glycine max), one of the most important crops in Brazil, due to its great versatility, being used from animal feed to the production of biofuels. With the great demand for soybeans, it is necessary to increase production in an increasingly smaller area. Where the supply of nutrients becomes essential to meet the demand of the crop, in order to achieve high production. K is one of the most used fertilizers, as it is one of the most needed by the plant, behind Nitrogen. The lack of this nutrient influences the vegetative and reproductive growth, impairing the formation of pods and grains. With the high price of fertilizers, the producer seeks more viable, economical alternatives, always aiming at greater production with lower expenses. The objective was to evaluate the impact on productivity, PMG, total corrected weight and moisture. The form of evaluation was given by two treatments, with the application of K2O and without the application of K2O, whereas fertilized installments, I received 139kg/ha of K2O. The K source used was KCl, which is the most used source in agriculture, as it has higher concentrations of K. The application was carried out by broadcast and the phenological stage of the plant at the time of application was R1. Each treatment had twelve repetitions of 2.25m X 5m with an area of 11.25m2 per repetition, with a total area of 270m2 for the experiment, divided into three blocks. Within each repetition, an area of 0.9m X 4m with 3.6m2 was harvested. The variables: productivity, PMG, total verified weight and humidity, were observed in the analysis of variance by the F test and the averages detected by the Tukey test at 5% probability with the SISVAR software. It was verified that through the analysis of variance, it was verified that the potassium fertilization applied only in R1 is not capable of expressing productive gains. |

Com a grande demanda da soja se faz necessário o aumento da produção em um área cada vez menor. Onde a o fornecimento de nutriente se torna essencial para suprir a demanda da cultura, de forma de alcançar alta produção. O K é um dos fertilizantes mais usados, já que é uns dos mais requeridos pela planta, ficando para trás do Nitrogênio. A falta desse nutriente influencia no crescimento vegetativo e reprodutivo, prejudicando na formação das vagens e dos grãos. Com o alto preços dos fertilizantes o produtor busca alternativas mais viáveis, economicamente, visando sempre a maior produção com os menores gastos. Objetivou-se avaliar o impacto na produtividade, PMG, peso total corrigido e umidade. A forma de avaliação se deu por dois tratamentos, com a aplicação de K2O e sem a aplicação de K2O, onde as parcelar adubadas, receberam 139kg/ha de K2O. A fonte de K utilizada foi a KCl, que é a fonte mais utilizada na agricultura, por ter maiores concentração de K. A aplicação foi feita a lanço e o estádio fenológico da planta no momento da aplicação era de R1. Cada tratamento teve doze repetições de 2,25m X 5m com área 11,25m2 por repetições, possuindo 270m2 de área total do experimento, dividida em três blocos. Dentro de cada repetição foi colhida uma área de 0,9m X 4m com 3,6m2 . As variáveis: produtividade, PMG, peso total corrigido e umidade, foram submetidas à análise de variância pelo teste F e as médias comparadas pelo teste de Tukey a 5% de probabilidade com o software SISVAR. Verificou-se que através de análise de variância, constatou-se que a adubação potássica aplicada somente em R1 não é capaz de expressar ganhos produtivos.Universidade Federal de Mato GrossoBrasilInstituto de Ciências Exatas e da Terra (ICET) – AraguaiaUFMT CUA - AraguaiaAgronomia - CUAMarchi, Patrícia Gelli Feres de2954658739702700http://lattes.cnpq.br/2954658739702700Moraes, Milton Ferreira de1541223007968886http://lattes.cnpq.br/1541223007968886Marchi, Patrícia Gelli Feres de2954658739702700http://lattes.cnpq.br/2954658739702700Santos, Carlos Leandro Rodrigues dos0054668076313809http://lattes.cnpq.br/0054668076313809Melo, Suzana Pereira de0392957201020352http://lattes.cnpq.br/0392957201020352Souza, João Victor Lima2024-07-05T16:03:04Z2024-03-062024-07-05T16:03:04Z2023-05-12info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/datasetSOUZA, João Victor.
