Soybean is an important high-value crop but susceptible to soil-borne diseases. A field trial was conducted in Kazakhstan evaluate the effects of soybean cultivars and Fusarium root rot severity on physiology, chlorophyll fractions amino acids profile. The highest yield achieved 2018 (up 4 t ha-1) for K-9648 cultivar. greatest (90%) lowest plant high (20.8 cm), number beans per (54) were determined 2020 related with precipitations. Moreover, leaf position crucial determination fractions, among which values 4rd leaf. Average concentration non-essential, essential, aromatic aliphatic correlated development at flowering (r = 0.73) maturing stage 0.54), 0.64) precipitations 0.86). Thus, play role defense proteins biosynthesis against biotic stress factors. Interestingly, despite occurrence, there not mycotoxins seeds, indicate that they are distributed other organs from place their biosynthesis. This study indicated twelve cultivars, Tanais Isidor least heavier rainfalls this regard could be implemented agriculture agro climatic conditions Kazakhstan. However, aspect desired profile, cultivar most productive 2018-2020.
