Other claims from this paper (14)

Intervention effect Magnesium fertilization did not affect the grain or straw yield of oats in three seasons.
Intervention effect Magnesium fertilization did not affect grain weight or the rate of maturing of oats in the first year.
Intervention effect After the magnesium reserve was exhausted, annual magnesium fertilization was needed for an abundant oat crop.
Intervention effect Magnesium deficiency impeded development of the grain crop of oats more strongly than that of the straw crop.
Intervention effect Magnesium deficiency delayed the maturing of oats.
Intervention effect Magnesium deficiency resulted in small oat grains.
Intervention effect The potassium-to-magnesium ratio in annual fertilization did not affect oat yield.
Association The amount of nutrients used had a more important effect on oat yield than the ratio of the nutrients.
Intervention effect Increasing potassium had a diminishing effect on oat yield when plants were short of magnesium.
Intervention effect Increasing lime had a diminishing effect on oat yield when plants were short of magnesium.
Intervention effect Increasing nitrogen had a diminishing effect on oat yield when plants were short of magnesium.
Intervention effect Together with magnesium, potassium, lime and nitrogen increased both grain and straw yields of oats.
