Verbatim
e3“During the transition from the first-fourth rotation to the fifth-eighth, a significant decrease in the yield of field crops was established: winter wheat in the 3-field crop rotation by 0.87 t/ha or 26.6 %, 2-field by 0.72 t/ha or 22.4% and 4-field by 0.70 t/ha or 21.8 %; millet by 0.43 t/ha or 16.3 %, spring hard by 0.40 t/ha or 29.6 %, soft by 0.35 t/ha or 24.6 %.”

- Association The 4-field grain – fallow crop rotation gave the highest mean grain yield, 1.63 t/ha over 1989-2020.
- Association The 4-field grain – fallow crop rotation gave the highest grain yield, 1.82 t/ha, in the first-fourth rotations (1989-2004).
- Association The 4-field grain – fallow crop rotation gave the highest grain yield, 1.44 t/ha, in the fifth-eighth rotations (2005-2020).
- Intervention effect Absence of spring late crop (millet) in the 2-field rotation reduced grain yield by 0.11 t/ha compared with the 4-field rotation, on average over all years.
- Intervention effect Absence of spring late crop (millet) in the 3-field rotation reduced grain yield by 0.30 t/ha compared with the 4-field rotation, on average over all years.
- Intervention effect Absence of spring late crop (millet) reduced grain yield by 0.22 t/ha in the first-fourth rotations compared with the 4-field rotation.
- Intervention effect Absence of spring late crop (millet) reduced grain yield by 0.28 t/ha in the first-fourth rotations compared with the 4-field rotation.
- Intervention effect Absence of spring late crop (millet) reduced grain yield by 0.20 t/ha in the fifth-eighth rotations compared with the 4-field rotation.
- Intervention effect Absence of spring late crop (millet) reduced grain yield by 0.32 t/ha in the fifth-eighth rotations compared with the 4-field rotation.
- Intervention effect During the transition from the first-fourth to the fifth-eighth rotations, winter wheat yield in the 3-field rotation decreased by 0.87 t/ha or 26.6 %.
- Intervention effect During the transition from the first-fourth to the fifth-eighth rotations, winter wheat yield in the 2-field rotation decreased by 0.72 t/ha or 22.4%.
- Intervention effect During the transition from the first-fourth to the fifth-eighth rotations, winter wheat yield in the 4-field rotation decreased by 0.70 t/ha or 21.8 %.
- Intervention effect During the transition from the first-fourth to the fifth-eighth rotations, spring hard wheat yield decreased by 0.40 t/ha or 29.6 %.
- Intervention effect During the transition from the first-fourth to the fifth-eighth rotations, spring soft wheat yield decreased by 0.35 t/ha or 24.6 %.
- Association In all three spring crops the yield reduction is 2.0 times lower than that of winter wheat.
- Observation Winter wheat yield fluctuated within the limits of the experimental error across crop rotations.
