Other claims from this paper (6)
- Association Planting density was highly significantly negatively correlated with the percentage of head milled rice in hybrid rice.
- Association Planting seedling density was highly significantly positively correlated with the chalky percent in hybrid rice.
- Intervention effect Super sparse cultivation with 150-210 kg N per hm2 gave grain yield equal to the CK.
- Intervention effect Super sparse cultivation increased the percentage of head milled rice by 15.69% to 22.92% relative to CK.
- Intervention effect Super sparse cultivation decreased the chalky percent by 16.34% to 21.22% relative to CK.
- Intervention effect In super sparse cultivation, applying N 20 days after full heading increased the seed setting rate and the percentage of head milled rice.
