“…However, the SPAD index values, widely used as a non-invasive and non-destructive estimate of chlorophyll content were highly influenced biostimulant treatments ( Table 2). These findings have been observed in a wide range of horticultural crops including tomato, spinach, lettuce, melon treated with biostimulants of different origin including amino acids, protein hydrolysate as well as plant and seaweed extracts [7,13,18,26,[38][39][40][41]. The higher SPAD index values observed in spinach plants treated with biostimulants (PH, SWE or VO + SWE) could be also considered a mechanism by which biostimulant application can promote N uptake efficiency.…”

Plant biostimulants (PBs) such as protein hydrolysates and seaweed extracts are attracting the increasing interest of scientists and vegetable growers for their potential toenhance yield and nutritional quality. The current study assessed crop productivity, leaf colorimetry, mineral profile and bioactive compounds of greenhouse spinach in response to the foliar application of three PBs: legume-derived protein hydrolysate [PH], extract of seaweed Ecklonia maxima or mixture of vegetal oils, herbal and seaweed Ascophyllum nodosum extracts. Plants were PB-treated at a rate of 3 mL L −1 four times during their growth cycle at weekly intervals. Foliar PB applications enhanced fresh yield, dry biomass and leaf area of spinach in comparison with untreated plants. Improved yield performance with PB applications was associated with improved chlorophyll biosynthesis (higher SPAD index). The three PB treatments elicited an increase in bioactive compounds (total phenols and ascorbic acid), thus raised the functional quality of spinach. The application of PH enhanced K and Mg concentrations and did not result in increased nitrate accumulation as observed with the other two PB treatments. Our findings can assist vegetable farmers and the agro-food industry in adopting innovative and sustainable tools such as PB for complementing a high yield with premium quality.

“…Biostimulan adalah senyawa organik yang dalam jumlah sedikit dapat menunjang dan meningkatkan pertumbuhan dan perkembangan tanaman. Aplikasinya bertujuan untuk meningkatkan efisiensi penyerapan nutrisi, toleransi cekaman abiotik dan meningkatkan kualitas panen (Jardin, 2015). Saat ini biostimulan mulai banyak digunakan untuk meningkatkan pertumbuhan tanaman, terutama tanaman hortikultura dan beberapa tanaman pangan (Calvo et al, 2014;Santoso & Priyono, 2014).…”

“…Plant biostimulants, described as any substance or microorganism applied to plants with the aim of enhancing nutrition efficiency, abiotic stress tolerance, and/or crop quality traits (du Jardin, 2015), have a steadily growing market, according to market analysis reports (Marketsandmarkets.com, 2014). Microorganisms and their metabolites that are capable of enhancing soil fertility, crop growth, and/or yield could provide an alternative to agricultural chemicals (Von Bennewitz and Hlušek, 2006).…”

Plant biostimulants can enhance crop nutrition status, stress tolerance, yield and quality in environment-friendly manner. The aim of this study was to determine the effect of an algae and bacteria preparations on the yield and nutritional parameters of leaf and romaine lettuce cultivated for spring and summer crop. The application of a combined biostimulant consisting of plant growth-promoting bacteria (Bacillus licheniformis, Bacillus megatherium, Azotobacter sp., Azospirillum sp., and Herbaspirillum sp.) and fresh water algae (Chlorella vulgaris) was done by watering the lettuce every 14 days, and a determination of the fresh weight, total antioxidant capacity, and total carotenoids content was performed. The result revealed that the application of bacterial-algal preparation significantly affected the plant weight of both romaine and leaf lettuce in spring and summer seasons. The highest increase in the weight of romaine lettuce reached 18.9% in the spring crop, while in the case of leaf lettuce, biostimulant treatment led to a 22.7% higher weight in the summer crop. Total antioxidant capacity and total carotenoids content showed increased values in the summer crop of romaine lettuce, while for the leaf lettuce there were no differences between treatments. Therefore, the positive effect of bacterial-algal treatment on lettuce yield, total antioxidant capacity and total carotenoids confirm that it could be applied for improving romaine lettuce yield quality and quantity, especially in stress, summer conditions.
