Other claims from this paper (11)
- Intervention effect Phosphorus and potassium fertilisers exceeding the rate by 10-15% did not improve growth of the aboveground part and root system of winter wheat.
- Intervention effect Increasing the uniformity of fertiliser distribution had a positive effect on biometric indicators of winter wheat, in particular height and mass of the aboveground and root parts.
- Intervention effect Increasing the uniformity of fertiliser distribution resulted in higher winter wheat yields.
- Intervention effect Increasing the uniformity of fertiliser distribution resulted in higher winter wheat grain quality indicators.
- Observation The maximum growth rate of the aboveground mass of winter wheat occurred in the tillering phase.
- Intervention effect A 10-25% deviation from the optimal fertiliser rate changed winter wheat indicators by 10-72% relative to the control in the tillering phase.
- Intervention effect A 10-25% deviation from the optimal fertiliser rate changed winter wheat indicators by 6.4-25% relative to the control in the stem elongation phase.
- Intervention effect A 10-25% deviation from the optimal fertiliser rate changed winter wheat indicators by 38-46% relative to the control in the heading phase.
- Intervention effect The highest winter wheat yield (10.4 t/ha) was obtained with N38P98K98 applied pre-sowing.
- Intervention effect Increasing the fertiliser rate to 110-120% increased winter wheat protein content to 13.6-14.0%.
- Recommendation The authors suggest uneven-fertiliser effects on yield formation can be used in precision farming.
