Other claims from this paper (5)
- Association Variation in plant density and irrigation depth explained 28 to 77% of maize yield variation in high-uniformity, high-density experiments.
- Method / resource Using irrigation-depth distribution improved maize-yield simulation relative to average applied irrigation.
- Method / resource RMSE fell from 637 to 328 kg ha−1.
- Method / resource Without irrigation-depth distribution, maize yield was overpredicted by 3%.
- Method / resource Adding plant-density distribution did not improve maize-yield simulations.
