Resumo: For the use of the water resource in agriculture, greater efficiency is sought because of scarcity in certain regions. The objective of this study was to evaluate the effect of water deficit, applied in different phenological phases, on the growth, physiology and production of upland cotton BRS 286 and BRS 336 cultivars. The experimental design was a randomized complete block in a Split Plot scheme, with the six water deficit regimes, applied on the different cotton phenological phases, constituting the Plots, and the two upland cotton cultivars, the Subplots, in four repetitions. Upland cotton growth, physiology and yield variables were evaluated. The water deficit restricted the upland cotton growth of both cultivars, with the most sensitive phases being those of initial growth, flower bud and flower. The 14 - day deficit, applied in the different phenological phases, did not influence the photosynthesis of the plants of both cultivars, but it altered its stomatal conductance and transpiration. Phenological phases of flower and fruit were the most sensitive to water deficit due to lower production. The treatments with no deficits in the whole cycle and with deficits in the initial growth and open fruit stages of both upland cotton cultivars allowed a satisfactory productivity compared to the national average.

Objetivou-se avaliar o efeito do déficit hídrico, aplicado em diferentes fases fenológicas, sobre o crescimento, fisiologia e produção das cultivares BRS 286 e BRS 336 de algodoeiro herbáceo. O delineamento experimental foi blocos casualizados em parcelas subdivididas, com os seis regimes de déficits hídricos, aplicados em diferentes fases fenológicas do algodoeiro, formando as parcelas e, as duas cultivares de algodoeiro herbáceo, as subparcelas, em 4 repetições. Foram avaliadas as variáveis de crescimento, fisiológicas e produtividade de algodão em caroço do algodoeiro herbáceo. O déficit hídrico restringiu o crescimento de ambas as cultivares de algodoeiro herbáceo, com as fases mais sensíveis sendo as de crescimento inicial, de botão floral e de flor. O déficit de 14 dias, aplicados nas diferentes fases fenológicas, não influenciou a fotossíntese das plantas de ambas as cultivares, mas alterou a condutâncias estomática e a transpiração das mesmas. As fases fenológicas de flor e de maçã foram as mais sensíveis ao déficit hídrico por apresentarem menor produção. Os tratamentos sem déficit em todo o ciclo e com déficit nas fases de crescimento inicial e de capulho, de ambas as cultivares de algodoeiro herbáceo, permitiram produtividade satisfatória em relação à média nacional.Editora Verde2018-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfapplication/pdfapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/593310.18378/rvads.v13i3.5933Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 13 No. 3 (2018); 313 - 321Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 13 Núm. 3 (2018); 313 - 321Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 13 n. 3 (2018); 313 - 3211981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/5933/5884https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5933/5885https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5933/9700https://www.gvaa.com.br/revista/index.php/RVADS/article/view/5933/9701Copyright (c) 2018 Mailson Araújo Cordão et al.info:eu-repo/semantics/openAccessCordão, Mailson AraujoAraújo, Whéllyson PereiraPereira, José RodriguesZonta, João Henriquede Lima, Robson FelipeFerreira, Fagner Nogueira2021-06-14T13:13:59Zoai:ojs.gvaa.com.br:article/5933Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:29.413950Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false
