“…The protein hydrolysate treatment significantly increased shoot FW, DW, and root DW from 59 to 89 g, 5.5 to 7.7 g, and 0.52 to 0.80 g, respectively (Table 1). Consistent with the present study, PHs have been identified to enhance plant growth of many crops such as corn [Zea mays (Ertani et al, 2009)], kiwifruit [Actinidia deliciosa (Quartieri et al, 2002) (Colla et al, 2014;Parrado et al, 2008)], radish [Raphanus sativus (Liu et al, 2008)], and lily [Lilium (De Lucia and Vecchietti, 2012)]. The growth enhancement by PHs has been attributed to increased nutrient uptake, assimilation, and metabolism resulting from increases in soil microbial activity, improvement of micronutrient mobility and solubility, modifications in the root architecture of plants, in particular root length, density and number of lateral roots, and increases in activities of enzymes involved in nutrient metabolism (Colla et al, 2014(Colla et al, , 2015Garc ıa-Mart ınez et al, 2010;Lucini et al, 2015).…”

Protein hydrolysates (PHs) are an important group of plant biostimulants that have received increasing attention in recent years because of their positive effects on crop performance and contribution to agroecological sustainability. The aim of the study was to determine the effects of fish-derived PHs on growth, chlorophyll content and fluorescence, and leaf gas exchange of lettuce (Lactuca sativa) grown in a growth chamber. Fish-derived PHs were drench applied (300 mL of 3 mL·L−1) three times at 0, 14, and 24 days after transplanting (DAT), and lettuce were evaluated 30 DAT. Application of PHs significantly increased the lettuce leaf number per plant from 22 to 28, stem diameter from 1.37 to 1.68 cm, shoot fresh and dry weight (FW and DW) from 59 to 89 g and 5.5 to 7.7 g, and root dry weight from 0.52 to 0.80 g. It also significantly increased the leaf relative water content (RWC) from 87% to 90% and succulence from 267 to 288 g·m−2 water, but had no effect on specific leaf area (SLA). PHs significantly enhanced chlorophyll content, photosynthetic rate, stomatal conductance, and transpiration rate although they did not alter chlorophyll fluorescence. Our study indicated that plant biostimulants and fertilizer PHs improved plant performance and might have potential to be used for sustainable production of lettuce.

“…Ashrafuzzaman et al (2010) found that foliar application of GABA increased the growth of bitter gourd plant. Several researchers also found that foliar application of amino acids increased the biomass of leafy radish, wheat, lemon grass, bean and onion plants (Liu et al, 2008;Gupta et al, 2003;Gamal El-Din et al, 1997;Nassar et al, 2003;Amin et al, 2011). N contents of the amino acids might induce the growth of Eustoma seedlings.…”

“…They can also act as parts of co-enzymes or as precursors for biosynthesis, such as Glutamine and Ornithine which are precursors for nucleotides and polyamines, respectively (Alcázar et al, 2010). Foliar application of amino acids has positive effects on the growth, yield and quality of Urtica pilulifera (Wahba et al, 2015), alfalfa (Pooryousef and Alizadeh, 2014), chinese cabbage (Cao et al, 2010); leafy radish (Liu et al, 2008); Codiaeum variegatum (Mazher et al, 2011) and Japanese pear (Takeuchi et al, 2008), grape (GardeCerdán et al, 2015;Portu et al, 2015). Apart from this, the role of amino acids to act as bio-stimulants in plants under abiotic and biotic stress conditions has been demonstrated (Maini and Bertucci, 1999;Heuer, 2003;Sadak et al, 2015).…”

“…The beneficial effect of biostimulants with seaweed extracts or amino acids on plant growth and development, and on the quantity and quality of the yield, regardless of its developmental stage, was confirmed in numerous studies [13,34,35,[39][40][41][57][58][59][60][61][62]. An interesting solution is to combine these two components in a single preparation, as in the case of the Fylloton biostimulant (Biolchim Poland), which contains the extract of Ascophyllum nodosum (L.) Le Jolis, as well as vegetal amino acids.…”

Biostimulants are preparations that favorably impact the growth, development, and yield of plants. The research objective was to examine the effect of the frequency of use of Kelpak, Terra Sorb Complex and Fylloton biostimulants on improving the yield and nutritional properties of beans. Been seeds (variety Oczko) were sown in the first week of May in 2015, 2016, and 2017. During the growing season, Fylloton (1%), Terra Sorb Complex (0.5%), and Kelpak (1%) biostimulants were applied by single (BBCH 12-13) and double spraying of plants (BBCH 12-13, BBCH 61). All variants of treatment with biostimulants were compared with the control. Single application of Kelpak had a positive effect on increasing the number of pods. The double application of Kelpak increased the number and yield of seeds and protein contents. Double application of Fylloton increased the number of seeds, and application of Terra Sorb Complex increased the protein content in the beans. Application of all biostimulants increased the flavonoid content. Biostimulants containing seaweed (Kelpak–Ecklonia maxima extract) or amino-acid extracts (Fylloton–Ascophyllum nodosum extract and amino acids or Terra Sorb Complex–amino acids) increased the seed yield, while improving its quality by increasing the content of protein, polyphenols, and flavonoids. It was found that the double application of Kelpak biostimulant stimulated the yield and quality of beans to a greater extent.
