Other claims from this paper (15)
- Intervention effect Continuous wheat yields averaged about 75% of fallow yields when recommended N and P were applied.
- Intervention effect Yield variability was lower in rotations with high proportions of fallow than in continuous-type rotations.
- Intervention effect Fertilizer N increased yields of wheat grown on fallow by about 5%.
- Intervention effect Fertilizer N increased yields of wheat grown on stubble by about 7%.
- Intervention effect Application of P fertilizer increased yields of wheat grown on fallow and stubble by about 12%.
- Association Total wheat production was inversely related to the frequency of fallow in the rotation.
- Intervention effect Continuous wheat with N and P outproduced wheat grown on fallow in a 2-yr rotation by 53% over 12 years.
- Association Wheat yields were directly related to growing season rainfall.
- Observation Flax yields were generally poor because of low drought tolerance and poor competition with weeds.
- Observation Fall rye yields were generally higher than provincial averages.
- Intervention effect Protein concentration of wheat grown on fallow was about 15.9% and greater than that of wheat grown on stubble.
- Association P concentration of wheat grown on stubble was greater than on fallow, due to P dilution by yield.
- Association P concentration in wheat was directly related to rainfall.
- Intervention effect Volume weight of wheat was not greatly influenced by treatment.
- Observation Volume weight of wheat was above the base criterion of 74.5 kg/hL in all years.
