“…DANTAS (2010) used a white mantle and found that the air and soil temperature decreased in the management of watermelon. Pereira et al, (2021) found superior results, using black and gray mulching compared to the soil discovered in the productive aspects of Gladial melon. Its use takes place in the form of tunnels after the transplantation of seedlings until the beginning of flowering.…”

The melon (Cucumis melo L.) is a crop of great economic importance for the world, and in Brazil it is mainly intended for the export of its fresh fruits to the European market. In the North region, especially in Roraima, the cultivation of melon is one of the alternatives for exploring the cerrado areas, as its favorable edaphoclimatic conditions enable cultivation during the off-season in Brazil. The yellow melon is grown by most producers in Roraima, however, the technology adopted by the producers implies low yields and quality of the fruits required by the foreign market. The Northeast region of the country adopts techniques for the use of mulching (soil cover using polyethylene film), where beneficial factors are associated with curcubitaceae, protecting the soil against evaporation, saving water, energy, fertilizers and hindering pest infestation. (weeds and insects), and diseases. In addition, they use agrotextile to cover plants, which reduces the attack of pests and diseases in the melon crop. Thus, proper management provides good perspectives for the cultivation of melons with excellent quality, reducing the use of pesticides and being profitable for the producer. Therefore, in view of this context, this study sought to review inherent information on the efficiency of the use of mulching management associated with TNT in the melon crop.

“…These changes result in reduced accumulation and distribution of photoassimilates [9] and can compromise fruit yield and quality [10]. On the other hand, excess soil moisture can cause problems such as oxygen deficiency and increased disease incidence, leading to reduced productivity [11]. In this context, evaluating the physiological characteristics of watermelon crops under water restriction is important to understand the factors influencing the production of this vegetable under adverse conditions, especially in the Alagoas region, in which studies on this topic are still incipient.…”

Water availability is a limiting factor for plant production, especially in Brazilian semi-arid regions. The main aim of the study was to investigate the physiological effects of drought during the fruiting stage of watermelon cultivation. A completely randomized block design with four replications and six treatments varied by the number of lateral drip tapes (1 or 2) and the duration of drought stress (0, 4, and 8 days) was used. The following parameters were evaluated: relative chlorophyll content, relative leaf water content, electrolyte leakage, CO2 assimilation (A), stomatal conductance (gs), internal CO2 concentration, leaf temperature, transpiration (E), water use efficiency (WUE), carboxylation efficiency (CE), yield, thickness, diameter, length, and fruit °brix, at 4 and 8 days of drought. Drought negatively affected photosynthesis, particularly in treatments with a single dripper and 4 days of drought, resulting in reductions of up to 60% in A, 68% in gs, 44% in E, 58% in WUE, and 59% in CE, but did not have a significant effect on watermelon yield after 4 or 8 days of irrigation. It was concluded that drought influences the physiological responses of watermelon plants, mainly in reducing photosynthesis, but does not drastically affect fruit productivity in short periods of stress.

“…These changes culminate in decreased accumulation and distribution of photoassimilates (S. S. Soares et al, 2023), potentially compromising production and fruit quality (Melo et al, 2022). On the other hand, excessive soil moisture can induce issues such as oxygen deficiency and disease incidence, further jeopardizing yields (Pereira et al, 2021).…”

No semiárido do Nordeste do Brasil, a irregularidade de chuvas e elevada evapotranspiração proporcionam déficit hídrico nas plantas na maior parte dos meses do ano, destacando-se como fator limitante para produção de olerícolas. Assim, a identificação de estratégias capazes de amenizar os efeitos do déficit hídrico nas plantas é essencial para produção sob condições irrigadas. Nesse contexto, objetivou-se avaliar o efeito da adubação nitrogenada na morfofisiologia e nos componentes de produção de mini-melancia 'Sugar Baby'. O experimento foi conduzido na Fazenda Experimental ‘Rolando Rivas Castellón’, São Domingos, Paraíba, sob condições de casa de vegetação, utilizando-se o delineamento de blocos casualizados em esquema fatorial 4 × 4, correspondendo a quatro níveis de reposição hídrica (50, 75, 100 - controle e 125% da evapotranspiração real da cultura - ETr) e quatro doses de nitrogênio - DN (50, 75, 100 e 125% da dose recomendada), com 3 repetições, totalizando 48 plantas. Foram avaliadas as variáveis de trocas gasosas, os teores de pigmentos fotossintéticos, o conteúdo relativo de água e o extravasamento de eletrólitos, o crescimento e a produção de fitomassa, os componentes de produção e a qualidade pós-colheita dos frutos de mini-melancia. A irrigação deficitária com 50% da evapotranspiração real inibiu as trocas gasosas, a síntese de pigmentos fotossintéticos, o crescimento, e a qualidade dos frutos da mini-melancieira ‘Sugar Baby’, independente da dose de nitrogênio. A lâmina de água com 125% da evapotranspiração real combinada à adubação de 100% da recomendação de nitrogênio proporcionou maiores teores de clorofilas totais, número de folhas e de fitomassa seca das raízes, caule, total, parte aérea e pH dos frutos de mini-melancieira ‘Sugar Baby’.
