Resumo: Sorghum bicolor is an important grain species used for food and feed production, where P is a key element/nutrient in grain production. The effect of increasing phosphorus doses to grain sorghum in Cerrado soil with sandy texture and low fertility in Cerrado conditions was evaluated. The study was conducted at the Pântano Farm, Jataí, Goiás, Brazil. The sorghum cultivar used was AG 1085. The doses of 0 (control), 40, 80, 120, and 160 kg ha-1 of P2O5 were used, whose source was triple superphosphate 46% of P2O5, with five replications each, designed in random blocks. The evaluated variables were stem length, stem diameter, leaf area, shoot dry mass, leaf phosphorus content, nutrient accumulation, fertilization efficiency, chlorophyll a, and chlorophyll b. For the variables shoot dry mass in (g plant-1), leaf phosphorus content, dry mass expressed in (kg ha-1), and chlorophyll b (CFI), the effect for the application of P doses in cultivar had a linear effect. The analysis of variance of the regression showed a quadratic effect for the variables stem length, stem diameter, leaf area, and phosphorus use efficiency, and for chlorophyll a (CFI), showing a maximum point at the best dose and best values ​​of the variables. The application of Phosphorus influenced the development of the grain sorghum cultivar. The 129 kg ha-1 of P2O5 had the highest efficiency of phosphorus fertilization corresponding to 82.02%.

Foi avaliado o efeito da adição de doses crescentes de fósforo em sorgo granífero em solo de Cerrado com textura arenosa e baixa fertilidade nas condições de Cerrado. O estudo foi realizado na Fazenda Pântano, Jataí, Estado de Goiás, Brasil. O cultivar de sorgo utilizado foi AG 1085. Foram utilizadas as doses de 0 (controle), 40, 80, 120 e 160 kg ha-1 de P2O5, cuja fonte foi o superfosfato triplo 46% de P2O5, com cinco repetições cada, delineamento em blocos ao acaso. As variáveis avaliadas foram: comprimento do caule, diâmetro do caule, área foliar, massa seca da parte aérea, teor de fósforo na folha, acúmulo do nutriente, eficiência de adubação, clorofila a e clorofila b. Para as variáveis massa seca da parte aérea em (g planta-1), teor quantitativo de fósforo foliar, massa seca expressa em (kg ha-1) e pigmento clorofiliano b (ICF), o efeito para a aplicação das doses de P na cultivar tiveram efeito linear. A análise de variância da regressão exibiu efeito quadrático para as variáveis comprimento do caule, diâmetro do caule, área foliar, eficiência do uso de Fósforo e para a clorofila a (ICF), apresentando ponto máximo na melhor dose e melhores valores das variáveis. A aplicação de Fósforo influenciou no desenvolvimento do cultivar de sorgo granífero testado. A dosagem 129 kg ha-1 de P2O5, exibiu maior eficiência da adubação fosfatada correspondente a 82,02%.Universidade Estadual de Mato Grosso do Sul, Unidade Universitária de Cassilândia2023-05-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicosonline.uems.br/index.php/agrineo/article/view/703910.32404/rean.v10i2.7039Revista de Agricultura Neotropical; v. 10 n. 2 (2023): REVISTA DE AGRICULTURA NEOTROPICAL; e7039REVISTA DE AGRICULTURA NEOTROPICAL; Vol. 10 No. 2 (2023): REVISTA DE AGRICULTURA NEOTROPICAL; e70392358-6303reponame:Revista de Agricultura Neotropicalinstname:Universidade Estadual de Mato Grosso do Sul (UEMS)instacron:UEMSenghttps://periodicosonline.uems.br/index.php/agrineo/article/view/7039/5419https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCarvalho, Felipe HernandesAlves, José MiltonGonçalves Veloso, ThaisSouza Alcântara, RitianeAbadia Ventura, Matheus ViniciusFernandes Batista Ventura, Hellen Regina2023-06-19T15:25:32Zoai:ojs.pkp.sfu.ca:article/7039Revistahttps://periodicosonline.uems.br/index.php/agrineoPUBhttps://periodicosonline.uems.br/index.php/agrineo/oaiagriculturaneotropical@uems.br || wellingthon.junnyor@uems.br2358-63032358-6303opendoar:2023-06-19T15:25:32Revista de Agricultura Neotropical - Universidade Estadual de Mato Grosso do Sul (UEMS)false
