The paper presents the results of the effects of various doses of mineral and biological fertilizers on the growth, development, progression of phenological stages, and yield of pea and bean crops under mountain conditions (Lake Sevan basin). Field experiments were conducted in 2024-2025 in the Martuni community.
Field experiments for each crop were established using five variants with three replications; the area of each experimental plot was 50 m². Variants (N30P60K60, N30 + ecobiofid+ 10 l/ha, ecobiofid+ 10 l/ha, and biohumus 2 t/ha) were compared with the control variant, in addition the effect of seed treatment with rhizotorphin was also assessed.
The results showed that fertilization promoted plant growth, extended the vegetation (6-9 days), and improved the structural elements of the crop. Increases in plant height, pod number, weight per thousand seeds, and number of seeds per pod were recorded in the fertilized variants. Pea yields ranged from 27.2 to 31.9 c/ha (Control: 20.4 c/ha), and bean yields ranged from 15.8 to 22.4 c/ha (Control: 12.8 c/ha). The most effective variants were N30 + ecobiofid+ 10 l/ha and biohumus 2 t/ha.
Seed treatment with rhizotorphin also resulted in significant yield increases: 9.6-22.1 % in peas and 19.6 % in beans. These results indicate that the combined application of mineral and biological fertilizers under mountainous conditions increases legume yields and can get the recommendation for practical agricultural use.
