“…The results relative to the concentration of micronutrients in our study differ from those reported in prior research conducted on oats (Oryza sativa L.) [49] and wheat [46]. An increase in Fe content was seen after the application of nTiO 2 in both oats and wheat.…”

“…Regarding the impact of nTiO 2 on mineral content, Alharby et al [46] observed comparable findings to ours in wheat. They found that the application of nTiO 2 led to an increase in P and K in both the shoots and roots, specifically when nTiO 2 was sprayed at a concentration of up to 400 mg kg −1 of soil.…”

“…In contrast to our findings, Mattiello and Marchiol [14] observed an elevation in the concentrations of Fe, Zn, and Mn in barley grains. Similarly, Alharby et al [46] reported an increase in Fe and Mn in the shoots and roots as well as in the grain of wheat plants when exposed to nTiO 2 at a soil concentration of up to 400 mg kg −1 . Similarly, the use of nTiO 2 particles with a size of 83 nm on fenugreek leaves resulted in elevated levels of Zn and Mn in both the leaves and stems; however, Fe and Cu decreased in comparison to the utilization of NPs with a size of 23 nm [48].…”

Nanotechnology has developed materials that can increase food production while reducing the use of conventional fertilizers. In this study, the effect of two forms of application (foliar and drench) as well as covering or non-covering of the surface of titanium dioxide nanoparticles (nTiO2) with maltodextrin (MDX) at 1500 ppm was investigated on tomato plants. The results show that treatment of tomato with nTiO2 increased yield (+21%), while covering the surface of the NPs resulted in a further yield increase (+27%). Similar trends were observed in the dry weight of vegetative plant parts. Fruit firmness (+33%) and total soluble solids (+36%) were enhanced by MDX-covered nTiO2. Application of nTiO2 resulted in enhanced SPAD index, photosynthesis rate, NO3−, K, and Ca concentration in the petiole sap, whereas in the fruits there was an increase in P and K in MDX-covered nTiO2. Considering the dilution effect due to the higher fruit yield, N, P, Mg, Cu, and B increased in plants treated with nTiO2. Covering the surface with MDX resulted in an enhanced response to nTiO2, as fruit yield and quality increased compared to plants treated with non-covered nTiO2.

“…Vigor index I and II in GA 3 treatments could be caused by the high production of photosynthates, leading to a greater vigor index (Anburani & Shakila, 2010). Increased vigor index of Amaranth and C. gynandra might be caused by improved nitrate uptake caused by the application of exogenous GA 3 (Alharbyet al., 2021). Al‐harthi et al.…”

Seed dormancy is the major challenge in the cultivation of Amaranth and Cleome gynandra. Amaranth and C. gynandra are affected by chemical, physical, and physiological dormancy. The current study was conducted at the Marondera University of Agricultural Sciences and Technology (MUAST) farm in 2021 and 2022. The effects of gibberellic acid and potassium nitrate seed treatments on the emergence and seedling vigour of Amaranth and C. gynandra were evaluated. Seeds of Amaranth and C. gynandra were pre‐soaked in gibberellic acid (control 0, 100, 200, 300,400, and 500 ppm) and potassium nitrate (control 0%, 0.1%, 0.2%, 0.3%, 0.4%, and 0.5%) solutions for 24 h to have a factorial layout within a randomized complete block design replicated three times. Seeds of Amaranth and C. gynandra treated with gibberellic acid showed a significant difference while potassium nitrate showed no significant difference. The highest emergence percentage and vigor index were recorded in seeds treated with 500 ppm gibberellic acid. The maximum emergence percentages of Amaranth (62.1%) and C. gynandra (60.7%) were obtained in 2022 and 2021. The least emergence percentages of Amaranth (46.4%) and C. gynandra (45.3%) were obtained in control in 2021. The highest vigor index of Amaranth (603) was obtained in 2022, while the highest vigor index of C. gynandra (562) was obtained in 2021. The lowest vigor indices of Amaranth and C. gynandra were 341 and 270, which were recorded in 2021 and 2022. The results showed that gibberellic acid has the potential to reduce seed dormancy.

“…Gibberellic acid is an important hormone in defending the plant against stress conditions (Alharby et al, 2021). Studies have shown that externally applied gibberellic acid can increase seed germination and salt tolerance of seeds (Chauhan et al, 2019;Oral et al, 2019;Ali et al, 2021).…”

Salinity is an important problem all over the world. The destructive effect of salinity is observed from the seed germination stage. In this study, it was aimed to determine the effect of salinity on seed germination of the medically important Satureja thymbra L., whether pre-treatments are a factor in breaking the salinity stress, and to determine the level of salinity tolerance of this species. In the research, firstly, the seeds were exposed to two pretreatments (80°C (5 minutes) + 10 ppm GA3 (24 hours), 80°C (5 minutes) + 100 ppm GA3 (24 hours)) and then 8 different NaCl concentrations (0.1 g/l, 1 g/l, 2.5 g/l, 5 g/l, 7.5 g/l,10 g/l, 15 g/l and 30 g/l) were tried. Germination seeds were counted every day and the effects of salinity on germination characteristics were investigated. The highest germination percentage (90%) was obtained at 0.1 g/l NaCl after 80°C (5 min.) + 100 ppm GA3 (24 h.) pretreatment. The results showed that the effect of salinity was significant on germination parameters in p < 0.05. Obtained results showed that the highest NaCl concentration at which Satureja thymbra seed could germinate was 10 g/l.
