EFFECT OF DIFFERENT TILLAGE PRACTICES ON SPRING BARLEY ON CROP YIELDS

Abstract

The article presents the productivity and quality characteristics of spring barley under different tillage intensities. A long-term field experiment was set up using the field splitting method, carried out in 4 replications. A total of 9 plots of each plant. The initial plot size was 126 m² (14 × 9 m), and the accounting plot was 70 m² (10 × 7 m). The plots of the experimental variants were arranged in a randomized manner. The field buffer strip was 4.5 m wide, and the interval between replicates was 9 m wide. The crop rotation was as follows: Crop rotation: 1) winter rapeseed; 2) winter wheat; 3) beans; 4) spring barley. All tillage systems were studied. Conventional deep plowing with a depth of 23–25 cm (DP) (control – comparative variant); Shallow plowing 12–14 cm deep (SP); Deep loosening (with a cultivator with arrow coulters) 23–25 cm deep (DC); Shallow loosening (with a disk harrow) 8–10 cm deep (SC); Direct sowing. (NT). The studies were conducted in a long-term stationary field experiment, which is located at the VMU Agricultural Academy Testing Station. The studies were conducted in 2024. The studies found that in fields where simplified tillage was applied, the number of productive stems of spring barley and its yield increased, but germination and grain protein content decreased compared to deep plowing fields.
