“…Seaweeds increase the quality and performance of plants by containing cytokinins that plants need [32]. Mohammed et al [33], in their study on lettuce, reported that the number of leaves and leaf area decreased depending on the dose increase of SW applications, had no effect on stem diameter and chlorophyll content, however increased head weight and yield. Demir et al [34] observed that SW extracts were effective in seedling growth and accelerated growth.…”

In recent years, environmental pollution problems have increased due to organic wastes. The use of organic wastes as fertilizer plays an important role in reducing environmental pollution and improving the physical, chemical and biological properties of the soil. This study was carried out to determine the effect of unprocessed olive pomace (OP) which is a by-product of olive oil industry and seaweed (SW) on the growth of pepper seedlings. In the study, 4 different pomace ratios (5% OP + 95% peat, 10% OP + 90% peat, 15% OP + 85% peat and 20% OP + 80% peat V:V) and 4 different SW extract doses ( 0% 0.5%, 1% and 2% ) were used. In the study, parameters such as plant height, stem diameter, leaf area, plant fresh and dry weights, and chlorophyll index were investigated. According to the results of the study, OP applications significantly decreased the stem diameter, leaf area, leaf number, leaf dry weight, stem dry weight, root dry weight, chlorophyll content, stem-root ratio and total plant dry weight, while root length increased. On the other hand, SW applications had no an important effect on plant growth but partially imporoved in the zero OP application.

“…On the other hand, the 'b' scale discerns between yellow and blue, with a positive value denoting yellow and a negative value denoting blue. Although a slight enhancing effect of biofertilizers on the SPAD-chlorophyll content was observed, no significant difference was found among the applications [8]. Gupta et al [59] utilized the beneficial fungus Talaromyces strain as a biostimulant for lettuce growth, and they reported an increase in photosynthetic pigments.…”

“…Agriculture is the largest sector that consumes water globally, accounting for approximately 70% of the total water demand [6,7]. Implementing an integrated irrigation and fertilization program is essential to achieving a maximum yield and high-quality production while adhering to an eco-friendly approach [8,9]. There is a growing interest in innovative farming practices characterized by a high water use efficiency and a high yield per unit area, driven by novel plant nutrition techniques.…”

“…The excessive use of mineral-chemical fertilizers to achieve high yields per unit area has a detrimental impact on the environment. Therefore, researchers are striving to promote environmentally friendly organic fertilizers, such as biofertilizers, to reduce the environmental hazards caused by mineral fertilizers [8,25]. Biofertilizers were introduced as a sustainable alternative to chemical fertilizers, posing adverse effects on living organisms and the environment.…”

“…Bio-fertilizers enhance plant growth, including increasing the number of leaves, leaf area, length, shoot fresh and dry weight and root fresh and dry weight [32][33][34]. Additionally, bio-fertilizers can mobilize mineral elements from an unavailable to an available form, thereby increasing the availability of both micro and macro nutrients for plants [8,35]. Soil naturally contains beneficial microorganisms supporting plant nutrition, producing phytohormones, controlling phytopathogens and improving the soil structure.…”

Hydroponics is a contemporary agricultural system providing precise control over growing conditions, potentially enhancing productivity. Biofertilizers are environmentally friendly, next-generation fertilizers that augment product yield and quality in hydroponic cultivation. In this study, we investigated the effect of three bio-fertilizers in a hydroponic floating system, microalgae, plant growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF), combined with a 50% reduction in mineral fertilizer, on lettuce yield and quality parameters including antioxidants: vitamin C, total phenols and flavonoids. The treatments tested were: 100% mineral fertilizer (control 1), 50% mineral fertilizer (control 2), 50% mineral fertilizer with microalgae, 50% mineral fertilizer with PGPR and 50% mineral fertilizer with AMF. The research was conducted during the winter months within a controlled environment of a glasshouse in a Mediterranean climate. The PGPR comprised three distinct bacterial strains, while the AMF comprised nine different mycorrhizal species. The microalgae consisted of only a single species, Chlorella vulgaris. AMF inoculation occurred once during seed sowing, while the introduction of PGPR and microalgae occurred at 10-day intervals into the root medium. Our findings revealed that the treatment with PGPR resulted in the highest growth parameters, including the lettuce circumference, stem diameter and fresh leaf weight. The 100% mineral fertilizer and PGPR treatments also yielded the highest lettuce production. Meanwhile, the treatment with AMF showed the highest total phenol and flavonoid content, which was statistically similar to that of the PGPR treatment. Furthermore, the PGPR recorded the maximum range of essential nutrients, including nitrogen (N), potassium (K), iron (Fe), zinc (Zn) and copper (Cu). Thus, the inclusion of PGPR holds promise for optimizing the lettuce growth and nutrient content in hydroponic systems. In conclusion, PGPR has the potential to enhance nutrient availability in a floating hydroponic system, reducing the dependence on chemical fertilizers. This mitigates environmental pollution and fosters sustainable agriculture.
