The aim of the present study was the impact of Aminobest product on grass stand height, plant density and forage productivity in Prista 5 alfalfa variety to be determined. The study was carried out on the specific soil and meteorological conditions of the experimental field of Institute of Agriculture and Seed Science “Obraztsov chiflik”- Rousse during 2014-2017. The experiment included variant with Aminobest application and control (untreated variant). Aminobest is a organic foliar fertilizer - a liquid formula based on amino acids and peptides in combination with soluble state of humic and fulvic acids. Alfalfa was grown without irrigation and green mass in early flowering stage was harvested. The foliar fertilization was performed twice (at 10-15 cm plant height and in a bud stage) in each regrowth, at 250 ml da-1 application rate for the product per treatment. Aminobest, had a different effect on the growth and development of the grass stands in Prista 5 alfalfa variety. The effectiveness of the product is strongly influenced by both the meteorological conditions during each regrowt in the different years and the specific variety response to changes of certain environmental factors. The foliar application of Aminobest contributed to the development of higher plants, significantly exceeding the control by value of the trait and exerted a slight positive influence on the potential for stem formation. It was found a clear expressed positive effect of Aminobest on green mass yield. Aminobest organic product used in the alfalfa growing for green mass gives promising results and can be used as a correctional component in technology for forage production.
