“…Even the increase in the content of photosynthetic pigments in this case post-treatment with spirulinabased spray fertilizer finds support in other studies [39,40]. A common result obtained after the application of biofertilizers, or biostimulants, is an increase in the photosynthetic activity, which reflects an increased synthesis of photosynthetic pigments (e.g., chlorophyll a, b, and carotenoids) [41,42]. Investigations conducted on seaweed extracts have shown that their administration to cultivated plants promoted plant development, leaf expansion, and the amount of photosynthetic pigments, due to the presence of plant growth regulatory substances (e.g., auxins, gibberellins, betaines, etc.)…”

Aquaponics represents an alternative to traditional soil cultivation. To solve the problem of nutrient depletion that occurs in this biotechnological system, the application of a spirulina-based biofertilizer was assessed. The microalgal waste used in this study came from industrial processing. Four different dilutions of the supernatant portion of this waste were sprayed on lettuce plants cultivated in an aquaponics system installed at the Botanical Gardens of the Tor Vergata University of Rome. The biofertilizer was characterized to evaluate its amount of macro- and micronutrients. The analysis conducted on the plants involved both morpho-biometric aspects and qualitative–quantitative measurements. The experiments showed that the spirulina extract had a positive effect on the growth and nutraceutical content of the lettuce plants; the obtained results highlighted that a dilution of 75% was the best for treatment. The use of the proposed organic and recycled fertilizer could increase the sustainability of crop cultivation and promote the functioning of aquaponics systems.

The study presents economic substantiation of applying environmentally friendly plant growth stimulators in combination with biological fungicides in sunflower production under conditions of the South of Ukraine. The field research was conducted at Kherson State Agricultural University (Ukraine) in 2017 – 2019 under conditions of dark chestnut alkaline soils with the humus content of 2.5% in the plough layer. The results of the three-year field research prove that the net profit reached the absolute maximum in the variant of the hybrid LG 5580 under conditions of applying the bio-fungicide Fitotsyd-r with the stimulator Ahrostymulin at the stage of budding and amounted to $1081/ha. In this case the cost price was the least – $141.6/ha, and the profitability level was the highest – 196%. In the areas sown with the hybrid Tunca the variant with the combination of Fitotsyd-r and the growth stimulator Ahrostymulin also provided a positive result, but it yielded a little to the combination of the preparations Fitosporyn / Ahrostymulin: the net profit was $579.7/ha, the price cost made $203.4/ha and the profitability was 106 %.On the whole this analysis makes it possible to maintain that additional costs related to purchasing and applying fertlizers are totally compensated owing to the cost of an increase in the yield.

“…Additionally, the application of AM fungi in hydroponic greenhouse crops will possibly help reduce challenges such as economic concerns envisioned by commercial vegetable growers, which may be encountered in pre-evaluating commercial mycorrhizal inoculants on selected crops and in regional soils before launching large-scale field use. A study using AM fungi and synthetic fertilisers on sunflower plants showed a greater plant height, stem diameter and leaf chlorophyll content, whereas there was increased mycorrhizal hyphal and arbuscular growth when AM fungi and organic fertilizers were used together [105]. Abobaker et al demonstrated clearly that AM fungi had beneficial effects on plant growth albeit without also having significant use of organic fertilizers [105].…”

This article discusses the utility of AM fungi in vegetable crop organic and hydroponic greenhouse production systems. A significant amount of work on field and organic crops utilizing AM fungi have proven their effectiveness in vegetable crops. The current article also addresses the major benefits of AM fungal application in nonhydroponic greenhouses, such as disease mitigation and improved production, and envisages the idea of utilizing some of these benefits for hydroponic greenhouse crops by designing appropriate experimental trials and performing a cost-benefit analysis while conducting such trials. AbstractArbuscular mycorrhizal (AM) fungi are considered to be enormously important in contemporary agriculture and horticulture for their ability to improve crop disease and fertility management in commercial field and greenhouse crop production. Recently, commercial greenhouse producers have begun using AM inoculum to increase yields and provide sustainable growing conditions in organic and hydroponic production systems. However, strong evidence in support of their effectiveness in hydroponic production is still lacking. Future research is expected to address benefits of the use of AM fungi in hydroponic greenhouse crops, such as defense against pathogen, herbivore attack and the effective management of photo-assimilates by plants, which are essential for fruit production. In order to increase our understanding of the usefulness of AM fungi in hydroponic greenhouses, large-scale trial and a cost-benefit evaluation of the process are needed. This article discusses the use of AM fungi for improving organic and hydroponic greenhouse crop production and disease control, considering that AM fungi inoculations in soil-based greenhouses and fields have proven to be very effective.
