Table 2.
The influence of the type of fallow in crop rotation, fertilizer systems and main soil tillage on the yield of winter wheat
| Factor and years studied | Variant of the experience | Yield, t/ha |
|---|---|---|
| Experimental field “5th crop rotation” | ||
| Fallow (1978-1992) | Black | 3.18 |
| Seeded | 2.89 | |
| Main soil tillage (1978-1992) | Plowing at 20–22 cm | 2.99 |
| Cultivation at 20–22 cm | 3.05 | |
| Shallow tillage at 10–12 cm | 3.04 | |
| Shallow tillage with discs at 8–10 cm | 3.10 | |
| Zero tillage | 3.00 | |
| Experimental field “Bee” | ||
| Fallow(1992-2001) | Black | 3.05 |
| Seeded | 2.02 | |
| Green-manured | 2.08 | |
| Fertilizer system (1992-2001) | Organic-mineral recommended | 2.48 |
| Organic-mineral intensive | 2.53 | |
| Organic | 2.22 | |
| Main soil tillage (1992-2001) | Cultivation at 20–22 cm | 2.42 |
| Shallow tillage at 10–12 cm | 2.40 | |
| Surface tillage at 6–8 cm | 2.40 | |
| Experimental field “Ugorye” | ||
| Fallow (2003-2010) | Black | 1.92 |
| Green-manured | 1.87 | |
| Main soil tillage (1992-2001) | Plowing at 20–22 cm | 2.63 |
| Shallow tillage at 10–12 cm | 2.61 | |
| Zero tillage | 2.61 | |
| The least significant difference (05) (LSD05): in “5th crop rotation” 0.13 for fallow type; 0.23 for main soil tillage; in “Bee” 0.22 for fallow type; 0.30 for fertilizer system; 0.10 for main soil tillage; in “Ugorye” 0.25 for fallow type; 0.30 for mail soil tillage. | ||
