Effect of bioslurries on tomato Solanum lycopersicum L and lettuce Lactuca sativa development

Bioslurries, obtained by anaerobic digestion of fresh organic matter, are emerging as a cheaper and low-impact alternative for synthetic products in agriculture. The aim this study was to evaluate bioslurry from biogas (Biog), plant nutrition FAO (Bfao), lactic fermentation (Blac) biostimulant tomato lettuce plants. Based on toxicity test, 10% dilution finally applied the In lettuce, Bfao Blac significantly increased aerial biomass (2.17 ±0.54 2.33 ±1.13 g respectively), regarding water control (1.16 ±0.60 g), while root only (1.60 ±0.44 g) compared (0.66 ±0.34 g). All digestates chlorophyll content index (CCI), yield (Fv/Fm) performance (Plabs) did not show differences with control. tomato, Bfao. CCI, Fv/Fm higher Blac, related PIabs showed no differences. both species, commercial fertilizer values all parameters. conclusion, stimulated growth, highest effect tomatoes followed Biog, being cheaper, safer lower-impact traditional crop growing. Highlights Digestates valuable by-products, different characteristics effects biomass, suggesting complex interactions. growth. digestate designed constituting an adequate strategy
