“…It also contains plant growth hormones that enhance yield (Latique et al 2013). Application of seaweed extract stimulates growth and yield and increases the tolerance of plants to environmental stress (Pramanick et al 2013), improves germination of maize seeds by 10-19%, promotes shoot and root growth by 30-68% (Matysiak et al 2011), increases the resistance of herbaceous plants to drought (Zhang and Ervin 2004), promotes vegetative growth, yield and oil content of peanuts (31.69%, 14.27%) and sunflower (31.69%, 14.27%), respectively (Karthikeyan and Shanmugam 2015). In addition, spraying plants with seaweed extract improves growth, yield and tuber quality of potatoes in terms of their nitrogen, total soluble solids and protein contents (Haider et al 2012), increases root growth, nutrient absorption, stem thickness and growth (Jensen 2004), ameliorates effect of salt stress on bean seeds because of the presence of growth hormones, nutrients and other important phytochemical compounds (Latique et al 2014).…”

To study the effects of mycorrhiza, fulvic acid, seaweed extract and urea on the physiological traits and leaf yield of tobacco, an experiment was carried out in split plots in a randomized complete block design with three replicates at Marivan during 2015. In this study, the main factor was two levels of inoculation with mycorrhiza including: control: no inoculation and inoculation with mycorrhiza (Glomus interaradices) and subplots treated with growth stimulants at 5 kinds: control-distilled water, fulvic acid, seaweed extract, urea, fulvic acid + seaweed extract + urea. The results indicate that the number of leaves and dry weight of the middle leaves of plants inoculated with mycorrhiza were increased significantly. In addition, the foliar application of growth stimulants significantly affected the relative water content, fresh and dry weight of the lower and middle leaves and also the greenness and fresh weight of the upper leaves of tobacco.

“…As for the salinity factor, the stress caused by excess ions compromises the photosynthetic system and reduces transpiration, gas exchange, and stomatal conductance, harming crop yield and justifying the reduction in achene yield as a result of increased salinity levels (Pan et al, 2021). Karthikeyan & Shanmugam (2015), in a study on applying algae-based biostimulants to sunflower crops, noted a 51.03% increase in crop yield compared to the control treatment. Similarly, Sîrbu et al (2022) found an 8% increase in sunflower yield when treated with algae-based fertilizer.…”

“…There is still little information on the agricultural use of algae extract in sunflower cultivation; however, in previous studies, some researchers have obtained increases in the production and yield of this crop. Sírbu et al (2022) found an 8% increase in sunflower yield when treated with algaebased fertilizer; Karthikeyan & Shanmugam (2015) observed a 51.03% increase in crop yield, while Suganthi & Sujatha (2014) found a 14% increase in the 1,000-achene weight of sunflower treated with algae compared to the control.…”

For the use of saline waters in agriculture to be a viable option, solutions must be adopted to mitigate the impacts caused by these waters. In this context, the present study aimed to evaluate the foliar application of algae (Ascophyllum nodosum) extract as a strategy to mitigate the deleterious effects of salinity on the production and post-harvest variables of the ‘BRS 324’ sunflower. The experiment was conducted in a randomized block design with a split-split-plot arrangement, composed of four salinity levels of water (1.2, 3.0, 4.5, and 6.0 dS m-1) and four doses of algae extract (0, 100, 150, and 200% of recommended dose) in two crop cycles, with four blocks. The 100% of the recommended dose (32 mg L-1) of the algae extract positively influenced the 1000-achenes weight (increases of 6.05 and 3.63% for the levels of 1.2 and 3.0 dS m-1, respectively) and the achene yield (increments of 7.07 and 4.59% for the levels of 1.2 and 3.0 dS m-1). The algae extract did not influence the oil and protein content and yield. The increase in salinity levels reduced all variables studied. Algae extract mitigated the deleterious effects of salinity on 1,000-achene weight and yield of achenes at the lowest water salinity level (1.2 dS m-1). The most effective dose of the algae extract to mitigate the negative effects of salinity on the 1,000-achene weight and achene yield was 100% (32 mg L-1) of the recommendation of the extract.

“…(Kumawat, P., & Dawson 2022) [19] . The Aquasap (Brand name of AquAgri for bio-stimulant of seaweed K. alvarezii) significantly increased the seed yield and oil content of peanut by 31.69% and 14.27%, similarly on sunflower the increase in seed yield and oil content was 51.50 and 15.77% respectively (Karthikeyan, K., & Shanmugam, M. (2015) [15] . Kiruthika et al, (2022) reported that application of 75% RDF + poultry manure @ 10 t ha -1 through soil application along with foliar application of 15% seaweed extract at 30 and 60 DAS and harvest stages recorded maximum soil nutrient availability [17] .…”

Oilseed crops are a diverse group of plants that include sunflower, canola, soybean, and rapeseed. They supply essential fatty acids and are a good source of essential carbohydrates, and vitamins A, D, E, and K. The oil cakes and oil meals are excellent sources of protein (40-60%) for both humans and animals. Oilseeds are integral to global agriculture due to their multifaceted utility in providing edible oils, biofuels, and industrial raw materials. Achieving sustainability in the production of oilseed crops is crucial as agricultural systems face challenges from climate change, degraded soil, and limited resources. The objective of this review is to compile the most recent findings regarding the development, yield, and quality of oilseed crops through the use of various bio-fertilizers, seaweed extracts, and nutrient management techniques. Through a thorough examination of the literature, this review explores the roles of nitrogen-fixing bacteria and phosphate-solubilizing bacteria in improving soil fertility and nutrient availability to oilseed crops. Additionally, it investigates the potential of seaweed extracts to stimulate plant growth, improve stress tolerance, and raise yield by activating defense mechanisms and regulating hormones. The results highlight the potential for boosting oilseed crop productivity through the integration of bio-fertilizers, seaweed extracts, and nutrient management techniques as sustainable substitutes to conventional chemical inputs. It demands further research and planning to create specialized agronomic techniques for enhancing the sustainability and resilience of oilseed crop production systems worldwide.
