“…Taken together, our results suggest that SA + Kh application was the most effective treatment. This result is in agreement with that reported by Shalaby et al [ 36 ], who found that the combined application of SA + Kh significantly enhanced the plant growth of marigold plants. Moreover, heatmap analysis ( Figure 6 B, group a) showed that SA and Kh treatments increased vegetative growth parameters under saline conditions.…”

“…Additionally, Kh was more effective than SA in improving plant growth ( Figure 2 ). This could be due to the role of potassium in controlling many enzymes in plants [ 56 ], as well as the role of humate as a biostimulants [ 36 ]. Taken together, our results suggest that SA + Kh application was the most effective treatment.…”

“…Treatment with SA might stimulate the activity of antioxidant enzymes, reducing the harmful effects of ROS under saline stress [ 68 ]. Previous studies indicated that SA application increases the activity of antioxidant enzymes under biotic stress conditions [ 36 , 69 , 70 , 71 ]. We also recorded an increase in the activities of CAT, SOD, and POX as a result of Kh treatment ( Figure 4 A–C).…”

“…The combination of SA as a foliar application and Kh as a soil application to mitigate abiotic stresses is rarely reported in the literature. For example, Shalaby et al [ 36 ] found that foliar application of SA + Kh enhanced plant growth, leaf pigments, and the activities of the antioxidant enzymes of marigold plants. Additionally, foliar application of SA + Kh enhanced the growth, photosynthetic pigments, and K accumulation of maize seedlings compared to control plants [ 37 ].…”

In the current study, we investigated the effect of potassium humate (Kh) and salicylic acid (SA) in mitigating the salinity stress of common bean plants. Common bean seedlings were treated with 0.2 g/L SA as a foliar application and 0.3 g/L Kh as a soil application individually or in combination. After 7 days of germination, plants were treated with 50 mM NaCl and normal water as a control. Our results indicate that salt treatment reduced the plant growth (fresh and dry shoots and roots), leaf pigments (total chlorophyll and carotenoids), ascorbic acid (AA), glutathione (GSH), and potassium (K) contents. On the contrary, proline content; sodium (Na); hydrogen peroxide (H2O2); superoxide anion (O2•−); and antioxidant enzymes, including catalase (CAT), peroxidase (POX), and superoxide dismutase (SOD), were increased by saline stress. However, applying either individual Kh and SA or their combination stimulated seedling growth under salinity stress by increasing growth parameters, leaf pigment contents, AA, GSH, proline content, K content, and antioxidant enzymes compared with the control. Additionally, Na content, H2O2, and O2•− were reduced by all applications. The application of the Kh (0.3 g/L) + SA (0.2 g/L) combination was more effective than using the individual compounds. In conclusion, applications of Kh + SA can mitigate salt stress and improve the seedling growth of common bean.

“…Our findings are in agreement with other results [ 91 , 92 , 93 ] which reported that the simultaneous increase in the activity of these antioxidant enzymes contributes to an increase in the application of brown seaweed liquid fertilizer. Similar observations were observed in the onion plant when treated with the foliar application of exogenous antioxidant compounds [ 94 , 95 , 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 ]. The author found an increase in POX activity when the plant was treated by alpha tocopherol.…”

Due to their distinctive physicochemical characteristics, nanoparticles have recently emerged as pioneering materials in agricultural research. In this work, nanopowders (NP) of seaweed (Turbinaria triquetra) were prepared using the planetary ball milling procedure. The prepared nanopowders from marine seaweed were characterized by particle size, zeta potential, UV-vis spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM) and X-ray diffraction (XRD). When the seaweed nanopowder of Turbinaria triquetra was subjected to FT-IR analysis, it revealed the presence of different functional groups, including alkane, carboxylic acids, alcohol, alkenes and aromatics. Moreover, the methanol extract was used to identify the polyphenolic components in seaweed (NP) using high performance liquid chromatography (HPLC) and the extract revealed the presence of a number of important compounds such as daidzein and quercetin. Moreover, the pot experiment was carried out in order to evaluate the effects of prepared seaweed (NP) as an enhancer for the growth of date palm (Phoenix dactylifera L.). The date palm seedlings received four NP doses, bi-distilled water was applied as the control and doses of 25, 50 or 100 mg L−1 of seaweed liquid NP were used (referred to as T1, T2, T3 and T4, respectively). Foliar application of liquid NP was applied two times per week within a period of 30 days. Leaf area, number of branches, dry weight, chlorophylls, total soluble sugars and some other secondary metabolites were determined. Our results indicated that the foliar application of liquid NP at T3 enhanced the growth parameters of the date palm seedlings. Additionally, liquid NP at T3 and T4 significantly increased the photosynthetic pigments. The total phenolic, flavonoid and antioxidant activities were stimulated by NP foliar application. Moreover, the data showed that the T3 and T4 doses enhanced the activity of the antioxidant enzymes (CAT, POX or PPO) compared to other treatments. Therefore, the preparation of seaweed NP using the planetary ball milling method could produce an eco-friendly and cost- effective material for sustainable agriculture and could be an interesting way to create a nanofertilizer that mitigates plant growth.

Research to study the effect of a good combination of growing media and application of N fertilizer on the growth and yield of cauliflower (Brassica oleracea, L.). The research time was carried out from June 2022 to October 2022 at Raya Village garden, Berastagi District, Karo Regency, North Sumatra Province, with an altitude of 1,300 above sea level with latosol soil type and soil pH 6.8. This research was conducted from June 2022 to October 2022. This research was conducted with a factorial experiment of 3x2 = 6 + 1 controls arranged in a factorial randomized block design (RAK). The first factor was the composition of the planting medium (M), which consisted of 3 treatment levels, namely: Mo: Control (without mixture), M1: Soil + husk charcoal with a volume ratio (1:1), M2: Sand + charcoal husk with a volume ratio (1:1) , M3: Soil + sand + husk charcoal by volume ratio (1:1:1) . The second factor was the dose of ZA (N) fertilizer which consisted of 3 treatment levels, namely: N1 : 50 kg/ha, N2 : 100 kg/ha, N3 : 150 kg/ha . The observed variables were plant height, number of leaves, number of roots, fresh weight of plants, fresh weight of flowers/plant, dry weight of plants, initiation of flowering, flower diameter. Mixing plant media and N fertilizer can increase the growth and yield of cauliflower plants. M3N3 treatment ( Soil + sand + husk charcoal with volume ratio (1:1:1) + Nitrogen fertilizer 150 kg/ha, is the best treatment that can increase growth and yield of cauliflower on the number of roots (7.27 fruit), fresh weight of plants (7.95 g), dry weight of plants (2.69 g), initiation of flowering (6.00 hst), fresh weight of flowers/plant (6.98 g), flower diameter (3.09 mm).
