Other claims from this paper (11)
- Intervention effect Oil radish green manure decreased the amount of seed weeds in the 0-30cm soil layer by 2.8-3.4 million seeds per hectare compared with the non-seeded background.
- Intervention effect Oil radish green manure decreased weed density in sugar beet by 0.5-6.5 weeds per square metre.
- Intervention effect Oil radish green manure decreased weed weight in sugar beet by 5.6-77.4 g per square metre.
- Intervention effect Mouldboard-free cultivation increased the quantity of weed seeds in the 0-10cm soil layer compared with plowing.
- Intervention effect Mouldboard-free cultivation decreased weed seeds deeper than 10cm compared with plowing.
- Intervention effect The deepest mouldboard-free cultivation gave the lowest amount of weed seeds in the 0-5cm layer, 24.5 and 23.5 million seeds per hectare.
- Intervention effect Decreasing the depth of mouldboard-free cultivation increased weed weight in sugar beet by 82.5-1193.5 g per square metre.
- Intervention effect Decreasing the depth of mouldboard-free cultivation caused a substantial shortfall in sugar beet root yield of 2.9-5.8 t/ha.
- Recommendation After-crop radish siderate with basic mouldboard-free cultivation reduces the potential amount of weed seeds in the 0-30 cm root layer.
- Intervention effect Deep soil cultivation on 28-30cm with the siderate background gave the greatest decrease in real weediness of sugar beet crops.
- Intervention effect Deep soil cultivation on 28-30cm with the siderate background gave high yields of 34.3 t/ha.
