Table 1.
Crop management data in the main experiment, as well as yield and N-yield in the non-fertilized plots (N0) in the three experimental years. Nfert I, II, and III indicate amounts and application dates for N dressings. For sowing, fungicide, and growth regulator, application dates (month/day) are given.
