Megjegyzések:	Brown juice is a byproduct of fractionated green biomass during leaf protein isolation. It represents approximately 45%?50% of the total pressed fresh biomass. Disposal of brown juice is a serious issue in leaf protein production due to its high biological oxygen demand and carbohydrates content. The current study aimed to find a possible potential use of brown juice. Therefore, chemical and biochemical properties of brown juice?derived from alfalfa green biomass?were determined before and after fermentation by lactic acid bacteria. Additionally, the growth stimulation potential of fermented brown juice on plumed cockscomb (Celosia argantea var. plumose 'Arrabona') plants were tested. Celosia seedlings were sprayed at different rates of fermented brown juice (i.e., 0.5%, 1%, 2.5%, 5%, and 10%) and tap water was applied as control. The results revealed that lactic acid bacteria successfully enhanced the stabilization of brown juice via reducing sugars content and increasing organic acids content. After fermentation, contents of glucose monomers were 15 times lower; while concentrations of lactic and acetic acids increased by 7- and 10-fold, respectively. This caused a reduction in the pH of fermented brown juice by 13.9%. Treating Celosia plants at lower rates of fermented brown juice (up to 1.0%) significantly induced their growth dynamics and antioxidant capacity. Higher values of vegetative parameters were measured in treated plants compared to control. The brown juice treatments caused significant changes in histological parameters as well. The activity of catalase and peroxidase increased in plants that received fermented brown juice especially at low rates. Moreover, an increase in water-soluble protein and phenol was measured in different tissues of plants sprayed with fermented brown juice. Malondialdehyde content was lowered in treated plants compared to control. Fermented brown juice at high rates slightly reduced the amount of photosynthetic pigments; however, this reduction was not reported for low rates of fermented brown juice. These results surely illustrate the potential use of fermented alfalfa brown juice as a growth stimulator for crops particularly at rates below 2.5%.

Megjegyzések:	ALFALFA is considered as "the Queen of the Forages" due to its high protein content and nutritional value. The production of alfalfa under different stressful environments is a great challenge, representing a serious threat to global food security. To improve the production of alfalfa under stressful conditions, there is a crucial need to understand the response of alfalfa plants to stresses, the mechanisms of tolerance and the management options. Alfalfa is a promising biorefinery crop from which leaf protein concentrates as well as bio-organic fertilizers can be produced. The potential of leaf-derived protein concentrate for human and animal nutrition is huge, yet unexploited. The bio-organic fertilizers derived from alfalfa plants represent a sustainable way to supply the plant with some nutrients. This review article highlights the sustainable use of alfalfa in biorefinery and bio-organic fertilizer production. Moreover, scattered knowledge about its use for production is collected supporting its suitability for improving soil fertility. Last, we discuss the suitability of alfalfa to produce stable yields in the light of changing climate and stressful conditions like salinity.

Megjegyzések:	Crop production is one of the most important agro-global issues, in particular questions of production under changing environmental conditions. This production needs to be increased to meet global needs for food, feed, fiber and fuel. Alfalfa is classified as "the queen of the forage crops" due to its high protein content and nutritional value as well as its unique availability during the summer compared with other forage crops. The production of alfalfa under different stressful environments is a great challenge due to several problems with alfalfa crop production, which represent a serious threat to global food security. These stresses may cause a decline in the global feed production from alfalfa due to harmful effects resulting from stresses at the physiological, biochemical and histological levels. To improve the production of alfalfa under these stresses, there is a crucial need to understand the response of alfalfa plants to stresses, the mechanisms of tolerance and the management options. The bio-organic fertilizers derived from alfalfa plants are a crucial and sustainable solution in particular under stressful environments. This review represents an attempt to highlight the positive sides of alfalfa production, particularly the sustainable use of this crop in bio-organic fertilizer production. The chemical and anatomical properties of this plant will also be reviewed. The histology of alfalfa plants under changing environments still needs further investigation.
