Physiological effects of humic substances on higher plants
Biostimulant activity of two protein hydrolyzates in the growth and nitrogen metabolism of maize seedlings.
Two protein hydrolyzate–based fertilizers, one from alfalfa and one from meat flour, were studied chemically and biologically and a role of amino acids and small peptides of the two PHFs is suggested in the regulation of the hormone-like activity and nitrogen pathway.

The results show that the humic fraction with low molecular size used in this study is endowed with the characteristic structural network described for most humic substances so far isolated and confirm the presence of IAA in this fraction.
Alfalfa plant-derived biostimulant stimulate short-term growth of salt stressed Zea mays L. plants
It is proved that the EM increases plant biomass even when plants are grown under salinity conditions, likely because EM stimulated plant nitrogen metabolism and antioxidant systems.

In light of these results, being environmentally friendly products, lignosulfonate-humate a and ligno-substance-based products could be used to increase crop yield.
Chemical and technological variables and their relationships: a predictive equation for pasta cooking quality.
Fifty samples of 10 Italian durum wheat varieties were analyzed by technological and chemical tests and 26 variables were obtained; their value in predicting pasta cooking quality was investigated.…

The results suggest that EM might promote nitrogen assimilation in plants through a coordinate regulation of C and N metabolic pathways and open the way for further research on protein hydrolysates as a valid tool to improve N use efficiency and, as a consequence, to reduce the intensive use of inorganic N fertilizers in agriculture.
