Other claims from this paper (18)
- Intervention effect Traditional plowing showed the highest soybean biological grain yield among the tillage systems.
- Intervention effect Replacing moldboard plowing and deep loosening with shallow tillage negatively affected soybean biological yield.
- Observation The average soybean biological grain yield over the research years was 2.76 t/ha.
- Observation The minimum soybean biological grain yield was 1.82 t/ha, in 2018 under no-till.
- Observation The maximum soybean biological grain yield was 3.88 t/ha, in 2021 under traditional primary tillage.
- Observation Average daily temperature in June increased by 2.0 ºC over the research period.
- Observation Average daily temperature in July increased by 1.1 ºC over the research period.
- Observation Average daily temperature in August increased by 2.0 ºC over the research period.
- Observation The average precipitation sum for June decreased by 23.2 mm over the past ten years.
- Observation The average precipitation sum for July decreased by 19.4 mm over the past ten years.
- Observation The average precipitation sum for August decreased by 34.4 mm over the past ten years.
- Association Soybean biological yield is related to the year conditions (r = 0.418).
- Association Soybean biological yield is related to the primary tillage system (r = 0.404).
- Association An increase in May temperature negatively affects soybean biological grain yield (r = –0.370).
- Association An increase in August temperature negatively affects soybean biological grain yield (r = –0.303).
- Association Average daily air temperature in June has a moderate direct correlation with soybean biological yield (r = 0.343).
- Association Average daily air temperature in July has a weak direct correlation with soybean biological grain yield (r = 0.111).
- Association Precipitation during May and June vegetative development practically does not affect soybean biological grain yield.
