Resumo: | It is believed that nitrogen fertilization will attenuate the salt stress on pearl millet plants. Thus, the objective was to evaluate the agronomic performance of the millet crop under different saline water irrigation strategies and nitrogen fertilization. The experimental design adopted was completely randomized (CRD), in a 4 x 2 factorial scheme, with 4 replicates, with the first factor being four irrigation strategies: S1 = low-salinity water (W1) = 0.3 dS m-1 throughout the cycle; S2 = saline water (W2) = 4.0 dS m-1 from 30 days after sowing - DAS; S3 = W2 from 45 DAS; and S4 = W2 from 65 DAS; and the second factor being two nitrogen doses (60 and 120 kg ha-1 of N). At the end of the experiment, the following variables were evaluated: photosynthesis, transpiration, stomatal conductance, instantaneous water use efficiency, internal CO2 concentration, leaf temperature, plant height, stem diameter, root length, panicle length, leaf dry mass, stem dry mass and root dry mass. Fertilization with 60 and 120 kg ha-1 promotes greater photosynthesis, transpiration, stomatal conductance and internal CO2 concentration in millet plants under the strategies S1, S2 and S3. The strategies S1 and S4 were more efficient to increase the efficient use of water and reduce leaf temperature. |

Acredita-se que a adubação nitrogenada atenuará o estresse salino sobre as plantas de milheto. Dessa forma, objetivou-se avaliar o desempenho agronômico da cultura do milheto sob diferentes estratégias de irrigação com água salina e adubação nitrogenada. O delineamento experimental adotado foi inteiramente casualizado (DIC), em esquema fatorial 4 x 2, com 4 repetições, sendo o primeiro fator, quatro estratégias de irrigação: S1 = água de baixa salinidade (W1) = 0,3 dS m-1 durante todo o ciclo; S2 = água salina (W2) = 4,0 dS m-1 utilizada a partir dos 30 dias após a semeadura – DAS; S3 = W2 a partir dos 45 DAS e S4 = W2 a partir dos 65 DAS; e o segundo fator, duas doses de nitrogênio (60 e 120 kg ha-¹ de N). Ao final do experimento foram avaliadas: fotossíntese, transpiração, condutância estomática, eficiência instantânea no uso da água, concentração interna de CO2, temperatura foliar, altura de planta, diâmetro do colmo, comprimento da raiz, comprimento da panícula, massas secas da das folhas, do colmo e da raiz. Adubações com 60 e 120 kg ha-¹ proporcionam maior fotossíntese, transpiração, condutância estomática e concentração interna de CO2 em plantas de milheto nas estratégias S1, S2 e S3. As estratégias S1 e S4 foram mais eficientes para aumentar o uso eficiente de água e reduzir a temperatura foliar.Universidade Federal Rural do Semi-Árido2023-02-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1096310.1590/1983-21252023v36n219rcREVISTA CAATINGA; Vol. 36 No. 2 (2023); 424-431Revista Caatinga; v. 36 n. 2 (2023); 424-4311983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/10963/11151Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccess de Có , Erickson GomesSousa, Geocleber Gomes de Gomes , Silas Primola Freire, Márcio Henriqeu da Costa da Silva, Fred Denilson Barbosa 2023-07-27T12:02:56Zoai:ojs.periodicos.ufersa.edu.br:article/10963Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:59.979607Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
