The effect of short peptides on the growth and yield of soybeans

Aim. Study of the effect of short di-and tetrapeptides (AB-0, AE-0) on the growth, development and productivity of Batya soybean varieties. Material and Methods. Biologically active dipeptide AB-0 and tetrapeptide AE-0 were used. Field studies were carried out on meadow-brown podzolized gley heavy loamy soil. One month before planting, soybean seeds were treated with dipeptide/tetrapeptide of concentrations of 0.01 g/l or 0.001 g/l. Hand-tended and industrial-level research was carried out. Results. The use of dipeptide AB-0 in a hand-tended study had a positive effect on the growth processes of soybeans of the Batya variety compared to the control. The use of tetrapeptide AE-0 in a hand-tended study increased the weight of plants by 7.3-67.0 g and plant height by 3.0-9.0 cm compared to the control. The use of dipeptide AB-0 and tetrapeptide AE-0 increased the yield of soybeans by a maximum of 81.2-83.7% compared to the control. The use of peptides AB-0 and AE-0 in an industrial-level experiment increased the yield by 30.5% and 18.4%, respectively, compared with the control. Conclusion. The short peptides AB-0 and AE-0 studied had an impact on the growth, development and productivity of Batya soybean varieties. They can be classified as plant growth regulators.
