Resumo: | Passion fruit cultivation relies on irrigation to increase yields in the semiarid of northeastern Brazil. Water scarcity is one of the factors that most affect crop physiology, leading to lower yields. Therefore, this study aimed to assess the influence of planting hole volume and application of a hydroretentive polymer on physiological and productive aspects of irrigated yellow passion fruit cv. BRS GA1 in the Northeast semi-arid region of Brazil. The experiment was conducted in randomized blocks, in a split-plot design 2 × (2 × 2). Treatments consisted of irrigation depths (100% and 70% of the crop's evapotranspiration requirement - ETc), planting hole volumes (64 dm3 and 128 dm3), and soil with and without application of hydroretentive Polymer (1.5 g dm3), with four replicates and three plants per plot. The analyzed variables included chlorophyll a and b indices, gas exchange, and yellow passion fruit yield. The findings showed that hydroretentive polymer application to the soil increases chlorophyll content and gas exchange in yellow passion fruit. Moreover, photosynthetic rates were not limited by a 30% reduction in irrigation depth and increased in plants grown in 128-dm3 planting holes with hydroretentive polymer. Based on yield results, irrigation depths can be reduced to 70% of the ETc by applying hydroretentive polymer in 64-dm3 planting holes. |

A escassez de água é um dos fatores que mais afeta a fisiologia das culturas, acarretando em baixas produtividades. Com isso, objetivou-se com a pesquisa avaliar a influência do volume de cova e aplicação de polímero hidrorretentor sob os aspectos fisiológicos e produtivos do maracujazeiro-amarelo cv. BRS GA1 irrigado no semiárido do Nordeste. O experimento foi conduzido em blocos casualizados, em parcela subdividida 2 × (2 × 2), referente às lâminas de irrigação de 100% e 70% da exigência evapotranspirativa da cultura, aos volumes de cova de 64 dm3 e 128 dm3, no solo sem e com 1,5 g dm3 do polímero hidrorretentor, com quatro repetições e três plantas por parcela. As variáveis analisadas foram índices de clorofila a e b, as trocas gasosas e a produtividade do maracujazeiro-amarelo. A adição do polímero hidrorrententor no solo proporciona maiores teores de clorofila e trocas gasosas no maracujazeiro-amarelo. A taxa fotossintética do maracujazeiro-amarelo cv. BRS GA1 não foi limitada com a redução da lâmina de irrigação em 30% da ETc e aumentou nas plantas cultivada no volume de cova de 128 dm3 com polímero hidrorrententor. Pelos resultados de produtividade do maracujazeiro-amarelo cv. BRS GA1, indica-se reduzir a lâminas de irrigação para 70% da ETc através da aplicação de polímero hidrorrententor nas covas de 64 dm3.UEL2023-12-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4643610.5433/1679-0359.2023v44n6p2045Semina: Ciências Agrárias; Vol. 44 No. 6 (2023); 2045-2062Semina: Ciências Agrárias; v. 44 n. 6 (2023); 2045-20621679-03591676-546Xreponame:Semina.
