Other claims from this paper (10)

Intervention effect Delaying seeding by 30 and 45 days from early May decreased grain yield of annual canarygrass.
Intervention effect Seeding rate had a small effect on grain yield of annual canarygrass.
Observation Grain yield of annual canarygrass peaked at approximately 1310 kg/ha at a seeding rate of 45 kg/ha.
Intervention effect Adding nitrogen fertilizer gave a small increase in grain yield of annual canarygrass.
Observation The fitted response curve estimated a maximum grain yield of 1215 kg/ha at a nitrogen rate of 78 kg/ha.
Intervention effect Most of the grain yield increase occurred with nitrogen between 20 and 40 kg N/ha, at 2.3 kg grain per kg fertilizer N.
Intervention effect Nitrogen above 40 kg/ha gave a slight increase in grain yield of annual canarygrass.
Intervention effect Nitrogen above 40 kg/ha increased the variation in grain yield of annual canarygrass.
Association Seeding date had a large effect on seed yield of annual canarygrass and could affect yield variability.
Intervention effect Seeding rate and nitrogen rate did not have a large effect on seed yield or yield variability of annual canarygrass.
