description Castor bean is a crop known to be drought tolerant, but like other crops, it shows reductions in yield under conditions of low water availability. Therefore, the objective whit this study was to evaluate leaf gas exchange, chlorophyll indices and yield of castor bean cultivars subjected to two contrasting water environments in the semi-arid region of Bahia, Brazil. Twelve castor bean cultivars were planted in a split-plot randomized block design, with the plot allocated to the contrasting water environments. Environment 1 was composed of irrigation close to field capacity, and environment 2 had about 30% of field capacity. Yield, leaf gas exchange, and chlorophyll content were evaluated. Statistical analyses were performed using Bayesian analysis with a variant of Hamiltonian Monte Carlo (HMC) to obtain Markov chains via Monte Carlo (MCMC). The MCMC were convergent and well mixed. In environment 2, the cultivars EBDA MPA 34, EBDA 17, and IAC 2028 showed yield above 1,700 kg ha-1. Cultivar IAC 226 showed an increase of 9.98% in its yield in environment 2. Therefore, cultivars EBDA MPA 34, IAC 2028, IAC 226, and EBDA 17 are recommended to castor bean breeding programs as promising parents for studies under conditions of low water availability. Cultivars EBDA MPA 11 and BRS Paraguaçu showed high yield in both environments and are recommended for cultivation because they are responsive to the increase in water availability.

Sendo assim, o objetivo com o presente estudo foi avaliar as trocas gasosas foliares, os índices de clorofila e a produtividade de cultivares de mamoneira submetidas a dois ambientes hídricos contrastantes no semiárido baiano. Doze cultivares de mamona foram plantadas em parcela subdividida em blocos casualizados, onde na parcela foi alocado os ambientes hídricos contrastante, o ambiente 1 foi composto por irrigação próxima a capacidade de campo e o ambiente 2 com cerca de 30% da capacidade de campo. Foram avaliadas a produtividade, trocas gasosas foliares e teores de clorofila. As análises estatísticas foram realizadas por meio da análise bayesiana com uma variante da Hamiltonian Monte Carlo (HMC) para a obtenção das cadeias ocultas de Markov via Monte Carlo (MCMC). As MCMC foram convergentes e bem misturadas. No ambiente 2 as cultivares EBDA MPA 34, EBDA 17 e IAC 2028 apresentaram produtividade acima de 1.700 kg ha-1. A cultivar IAC 226 apresentou um aumento de 9,98% em sua produtividade no ambiente 2. Já as cultivares EBDA MPA 34, IAC 2028, IAC 226 e EBDA 17 são recomendadas aos programas de melhoramento da cultura como genitores promissores para estudos em condições de baixa disponibilidade hídrica. As cultivares EBDA MPA 11 e BRS Paraguaçu apresentam alta produtividade nos dois ambientes sendo indicadas ao cultivo por serem responsivas ao aumento da disponibilidade hídrica.Universidade Federal Rural do Semi-Árido2024-10-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1249510.1590/1983-21252025v3812495rcREVISTA CAATINGA; Vol. 38 (2025); e12495Revista Caatinga; v. 38 (2025); e124951983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/12495/11649Copyright (c) 2024 Revista Caatingainfo:eu-repo/semantics/openAccessPeixouto, Yslai SilvaSilva, Luiz Mariano Neves daBrito, Alexsandro dos SantosPeixouto, Leandro SantosCosta, Marcio Gilberto Cardoso2025-04-04T14:17:19Zoai:ojs.periodicos.ufersa.edu.br:article/12495Revistahttps://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:2025-04-04T14:17:19Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)false
