Summary: This study explored how the combined use of microbial-based biostimulants and plant-derived protein hydrolysates (PHs) can enhance the tolerance of greenhouse-grown lettuce (Lactuca sativa L.) to the challenges posed by salinity and alkalinity, conditions
Summary: This study examined the effects of a plant-derived protein hydrolysate on greenhouse lettuce (Lactuca sativa) under salt stress conditions. The research focused on various plant growth parameters, including root morphology, SPAD index, chlorophyll fluorescence,
Summary: This study focuses on evaluating the biostimulant effects of two beneficial microorganisms—*Glomus intraradices* BEG72 (G) and *Trichoderma atroviride* MUCL 45632 (T)—on various vegetable crops. The study examines their individual and combined effects on plant
Summary: A greenhouse experiment was conducted on butterhead lettuce treated with protein hydrolysate biostimulants to test the “signaling peptide theory.” The study found that PH1 and PH3 significantly increased fresh yield under optimal conditions, but
Summary: The study aimed to evaluate the effects of three organic fertilizers on greenhouse lettuce’s morpho-physiological and agronomic traits under poor soil quality conditions. The tested organic fertilizers were poultry manure, vinasse-based fertilizer, and insect’s
Summary: Lettuce, a major food crop in the European Union, can associate with arbuscular mycorrhizal fungi (AMF), which can stimulate the synthesis of secondary metabolites, increasing plant tolerance to stresses and enhancing antioxidant compounds. A
Summary: Salinity is a significant issue for food production, and biostimulants can help protect crops from yield losses. A greenhouse experiment was conducted on lettuce plants under control and high salinity conditions using Trainer (T)
Summary: The study investigated the combined effect of phosphorus (P) application and arbuscular mycorrhizal fungi (AMF) on the growth and accumulation of arsenic (As) and phosphorus in lettuce plants grown in As-polluted soil. The experiments
Summary: The aim of this study was to investigate the potential of a commercial plant-derived protein hydrolysate, called ‘Trainer’, to enhance the growth and nitrogen uptake of maize and lettuce in a floating system using
Summary: Protein hydrolysates (PHs) represent a significant category of plant biostimulants, characterized by mixtures of polypeptides, oligopeptides, and amino acids derived from protein sources through partial hydrolysis. Typically applied as foliar sprays or near the
Summary: There is increasing evidence suggesting that various organic substances, including plant extracts and plant-derived protein hydrolysates, have the potential to enhance crop productivity and improve crop tolerance to abiotic stresses such as drought and
