“…However, a significant decrease in seed weight (TSW) was observed. Increases in tomato seed yield in plants exposed to low-to-medium N fertilization have been previously reported [5,30], but no evidence was found in the literature regarding tomato seed yield under high N fertilization. Tomato seed weight increases with increasing N fertilization [5], but beyond some thresholds (180 kg N ha −1 or 20 mM N) TSW drops [6,7].…”

Nitrogen fertilization is a key practice in agriculture and its effects on yield and quality of most commodity products are widely known. However, the response of seed production to N fertilization, especially with regard to its effects on seed quality, is still poorly understood. The objective of this study was to determine the effect of N fertilization on tomato seed yield and quality. Six quality attributes were assessed (weight, standard germination, germination rate under normal and adverse conditions, dormancy and longevity) in tomato cv. Moneymaker plants fertigated with one of three nutrient solutions differing in their N concentration: 5, 15 or 25 mM. Seed weight decreased by 4% with increasing N fertilization while standard germination and mean germination time did not vary among treatments, with average values of 89.7% and 6.2 days, respectively. The percentage and rate of germination decreased when seeds were imbibed in solutions with reduced osmotic potential; however, this effect was less pronounced in seeds from the 25 mM treatment, indicating a lower dormancy. When germination was evaluated after accelerated aging, seeds from the high N fertilization treatment showed greater longevity. These results contribute to optimizing fertilization practices for the production of high quality tomato seeds.

“…Salt stress also alters hormone-regulated responses, limiting stomatal opening and photosynthesis [ 4 ]. These changes caused phenological changes resulting in reduced leaf expansion and photosynthetic area, lower plant growth rates, and smaller fruits and seeds [ 5 ].…”

“…Brackish water desalination by reverse osmosis systems has guaranteed access to potable water for many communities in the Brazilian semi-arid region. However, water treatment by reverse osmosis generates brine waste, which must be used in fish farming or hydroponics to avoid soil contamination [ 5 ]. In this regard, using brackish water to prepare nutrient solutions for hydroponic crops is noteworthy as they do not present matric potential, and the roots are in a constant state of saturation, thus reducing the deleterious effects of salinity on the plants [ 9 ].…”

The economically profitable production of crops is related, among other factors, to seed quality, the production system, and the water used in irrigation or preparation of nutrient solutions. Therefore, the objective was to evaluate the phenology, production, and vigor of seeds of mini watermelons grown in saline nutrient solution and different substrates. In the fruit and seed production phase, the experiment occurred in a greenhouse with five electrical conductivities of water for nutrient solution preparation, ECw (0.5, 2.4, 4.0, 5.5, and 6.9 dS m−1), and two growing substrates (coconut fiber and sand). We evaluated the physiological quality of seeds previously produced under the five electrical conductivities of water and two substrates. High salinities for the hydroponic cultivation of the mini watermelon cultivar ‘Sugar Baby’ accelerated fruit maturation and crop cycle, decreasing fruit size. However, in both substrates, the seed production of mini watermelons, seed viability, and seed vigor occurred adequately with a reject brine of 6.9 dS m−1 in the hydroponic nutrient solution. The seed production of ‘Sugar Baby’ mini watermelons using reject brine in a hydroponic system with coconut fiber and sand substrates is viable in regions with water limitations.

“…A ARP também foi investigado como um método de irrigação alternativo para o cultivo de tomate cereja em ambientes protegidos. Quando combinada com água de baixa condutividade elétrica, a ARP demonstrou potencial como uma fonte benéfica de água e nutrientes (Silva et al, 2021). Em outro estudo envolvendo a mesma cultura, a irrigação com ARP proveniente da criação de tilápias resultou em maior produtividade em comparação com a irrigação com água de poço (Castro, Borges Azevedo, & Bezerra-Neto, 2006).…”

“…A ARP quando utilizada em outras culturas resultou no aumento da produtividade, como: repolho (Elsbaay & Darwesh, 2022), tomate cereja (Silva et al, 2021) (FAO, 1980;Suresh, 2016;Hua et al, 2019). Além disso, a presença de aditivos e aglutinantes na formulação pode influenciar os níveis de nutrientes observados (Bai, Katya, & Yun, 2015;Encarnação, 2016;Yadav et al, 2021).…”
