Resumo: The cultivation of irrigated guava in semi-arid areas highlights the need for information regarding its responses to irrigation water quality and the fertilization management that enables its exploitation. Thus, this study aimed to evaluate the effect of water salinity and nitrogen (N) doses on the growth and physiology of the guava cv. ‘Paluma’. The experiments was conducted in drainage lysimeters under field conditions in an experimental area at the Center of Sciences and Agri-Food Technology of the Federal University of Campina Grande (CCTA/UFCG), Campus II, in Pombal, PB, Brazil. The experiment had a randomized block design, and treatments consisted of a 5 x 4 factorial arrangement corresponding to five levels of irrigation water electrical conductivity, ECw (0.3, 1.1, 1.9, 2.7, and 3.5 dS m-1), and four N doses (70, 100, 130, and 160% of the recommended N dose). The 100% dose corresponded to 541.1 mg of N dm-3 of soil. Increments in irrigation water salinity from 0.3 dS m-1 led to a reduction in stomatal conductance, internal CO2 concentration, CO2 assimilation rate, transpiration, instantaneous water use efficiency, the number of leaves and branches, stem diameter, and absolute and relative growth rates. Nitrogen doses ranging from 378.7 to 865.7 mg of N dm-3 of soil did not affect gas exchange and plant growth. Although ‘Paluma’ guava growth was affected by increases in water salinity, these plants can be irrigated using water of up to 1.42 dS m-1 with an acceptable reduction of 10% in growth variables. The interaction between irrigation water salinity and N fertilization had no significant effect on any of the variables studied.

Assim, objetivou-se estudar o efeito da salinidade da água combinada com doses de nitrogênio no crescimento e fisiologia da goiabeira cv. ‘Paluma’, em experimento conduzido em lisímetros de drenagem sob condições de campo em uma área experimental no Centro de Ciência e Tecnologia Agroalimentar da Universidade Federal de Campina Grande (CCTA/UFCG), Campus II de Pombal, PB. O delineamento experimental utilizado foi de blocos casualizados, com tratamentos arranjados em esquema fatorial 5 x 4, relativos a cinco níveis de condutividade elétrica da água de irrigação – CEa (0,3; 1,1; 1,9; 2,7 e 3,5 dS m-1) e quatro doses de nitrogênio (70, 100, 130 e 160% de N recomendada), sendo a dose referente a 100% correspondeu a 541,1 mg de N dm-3 de solo. O aumento da salinidade da água de irrigação a partir de 0,3 dS m-1 promoveu redução na condutância estomática, concentração interna de CO2, taxa de assimilação de CO2, transpiração, eficiência instantânea no uso da água, número de folhas e ramos, diâmetro de caule, taxa de crescimento absoluto e relativo. Doses de nitrogênio variando de 378,7 a 865,7 mg de N dm-3 de solo não afetaram as trocas gasosas e o crescimento das plantas. Apesar do crescimento da goiabeira cv. Paluma ser afetado com o aumento da salinidade, é possível irrigar com água de até 1,42 dS m-1 ocorrendo redução aceitável de 10% nas variáveis de crescimento. Não houve efeito significativo da interação entre salinidade da água de irrigação e doses de adubação nitrogenada em nenhuma variável estudada.Universidade Federal Rural do Semi-Árido2018-10-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/718210.1590/1983-21252018v31n402rcREVISTA CAATINGA; Vol. 31 No. 4 (2018); 808-816Revista Caatinga; v. 31 n. 4 (2018); 808-8161983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/7182/9849Copyright (c) 2018 Revista Caatingainfo:eu-repo/semantics/openAccessBezerra, Idelfonso LeandroNobre, Reginaldo GomesGheyi, Hans RajLima, Geovani Soares deBarbosa, Joicy Lima2023-07-20T13:50:40Zoai:ojs.periodicos.ufersa.edu.br:article/7182Revistahttps://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:2024-04-29T09:46:33.844727Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
