Other claims from this paper (12)
- Association Water-K interactions significantly regulated canopy structure, photosynthetic traits and yield formation of potato.
- Intervention effect In the wet year (2022), moderate irrigation with a high K rate (W2K5) gave the highest potato tuber yield, 53.37 t/ha.
- Intervention effect In the wet year (2022), W2K5 also gave the highest water productivity, 12.43 kg/ha/mm.
- Intervention effect In the dry year (2023), full irrigation with a moderate K rate (W3K4) performed best, with a yield of 45.88 t/ha.
- Intervention effect In the dry year (2023), W3K4 gave a water productivity of 9.44 kg/ha/mm.
- Recommendation Regression models indicate the recommended irrigation range increased from 132.5-183.0 mm in the wet year to 259.9-282.3 mm in the dry year.
- Recommendation Regression models indicate the optimal K application range narrowed from 222.9-420.0 to 240.0-342.9 kg K/ha.
- Association PLS-PM showed water input drove evapotranspiration (beta = 0.91).
- Association PLS-PM showed K input drove plant K concentration (beta = 0.95).
- Association Canopy function drove yield formation (beta = 0.97).
- Association Yield increase had a positive effect on water productivity (beta = 1.19), stronger than the negative effect of increased ET.
- Association Increased evapotranspiration had a negative effect on water productivity (beta = -0.85), weaker than the positive effect of yield increase.
