Other claims from this paper (10)
- Intervention effect The highest soybean seed production, 2.08 t ha-1, was obtained under conventional tillage (I).
- Intervention effect Chisel + cultivator (III) decreased soybean seed yield essentially, by about 10.1%, compared with tillage systems I and II.
- Intervention effect Direct sowing (IV) decreased soybean seed yield essentially, by about 26.9%, compared with tillage systems I and II.
- Intervention effect Seed yield under direct drilling (IV) was essentially lower by 23.3% than under tillage treatment II.
- Intervention effect Seed yield under direct drilling (IV) was essentially lower by 18.7% than under tillage treatment III.
- Intervention effect Two-fold foliar nutrition of soybean plants with macro- and micronutrients made the seed yield higher by 10.2%.
- Intervention effect Tillage treatments did not influence substantially and clearly the straw yield of soybean.
- Intervention effect Soybean straw production was increased by foliar nutrition.
- Observation Soybean straw weight amounted to 1.80 to 2.05 t per ha in the consecutive years, and only in sporadic cases to 1.12 t ha-1 (in 2002).
- Association Soybean seed and straw yields were modified by variable weather conditions in the research years.
