Other claims from this paper (19)
- Intervention effect Fertilizer systems increased total sweet potato tuber yield by 5.3–8.7 t / ha or 34–56%.
- Intervention effect Fertilizer systems increased standard sweet potato tuber yield by 2.9–4.6 t / ha or 27–42%.
- Intervention effect The same fertilization system yielded 15.5 t / ha of standard tubers.
- Intervention effect Increasing mineral fertilizer from N185P185K225 to N370P370K450 produced no significant yield difference.
- Intervention effect Additional complex fertilizer gave a positive yield trend of 3.3 t/ha.
- Intervention effect Organic fertilizer increased total tuber yield by 6.7 t / ha or 43%.
- Intervention effect Adding microbial drugs to organic fertilizer did not significantly increase yield, which reached 22.8 t / ha.
- Intervention effect Organic fertilizer plus microbial preparations increased tuber dry matter to 18.6%.
- Intervention effect Organic fertilizer plus microbial preparations increased tuber starch to 9.06%.
- Intervention effect Organic fertilizer plus microbial preparations yielded low nitrate content of 28.1 mg / kg.
- Intervention effect Mineral and complex fertilizer increased tuber dry matter to 17.7%.
- Intervention effect The mineral plus complex fertilizer treatment had the highest nitrate content, 78.5 mg / kg.
- Intervention effect All fertilizer systems tended to reduce tuber total sugar; N370P370K450 plus Nutrivant gave 3.4% versus 4.74% in control.
- Observation Sweet potato absorbed up to 57% of mobile N, 11.6% of P, and 61.2% of K on chernozem.
- Observation Nutrient utilization from mineral fertilizer was 40.7% for N, 26.1% for P, and 73.5% for K.
- Observation Without fertilizer, most N, P, and K uptake occurred in the first two months of growth.
- Observation With mineral and organic fertilizer, nutrient consumption peaked at 2–3 months of growth.
- Observation Without fertilizer, end-season P and K uptake fell to 104.4 and 252.4 kg/ha.
- Observation Nutrient partitioning varied by fertilizer system, with most N, P, and K accumulating in leaves.
