Other claims from this paper (10)
- Intervention effect High residual P and K increased soybean yield by 43%.
- Intervention effect Nitrogen-containing starter fertilizers increased early root and top weights, especially with P.
- Intervention effect Potassium starter fertilizers did not increase early plant root and top weights.
- Intervention effect P, K, N-K and P-K starters increased yield by 46% against control when residual P or K was low.
- Intervention effect P, K, N-K and P-K starters increased yield by 26% against control when residual P and K were high.
- Intervention effect N, N-P and N-P-K starters increased yield 21% when residual P was low.
- Intervention effect N, N-P and N-P-K starters had no yield effect when residual P was high.
- Observation Seed quality did not vary among residual fertility levels.
- Association Leaf P and K concentrations corresponded to yield differences among residual fertility levels.
- Association Leaf P and K concentrations did not correspond to yield differences among starter fertilizers.
