Raili Jokinen Agricultural and Food Science 1977. doi:10.23986/afsci.71945

Other claims from this paper (14)

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.

Other claims from this paper (13)

Intervention effect Yields of grass given the larger N dressing were greater with ammonium nitrate than with ammonium sulphate.
Intervention effect Magnesium treatments significantly increased yields of the third cut given the most N, only when Mg concentration in dry matter was 0.07% or less.

Other claims from this paper (13)

Observation Low-temperature seed-yield loss arose mainly from reduced pod number or setting and fertile-seed percentage.
Observation Fertilizers differed statistically in pod number or setting rate.
Intervention effect Cold injury was least with farmyard manure and greatest with CDU.
Intervention effect Farmyard manure produced the highest total seed weight across cool treatments and control.
Intervention effect The four other slowly available nitrogen fertilizers exceeded high and standard ammonium sulfate for seed weight.
Intervention effect Leaf and stem weights at maturity were highest with farmyard manure.
Observation Nonnodulating soybean responded strongly to nitrogen fertilization in growth and yield, with a response trend contrasting with the nodulating line.

Intervention effect Deep plowing tended to decrease root yield of sudangrass.
Intervention effect Deep plowing tended to decrease root yield of sugarbeets.
Intervention effect Deep plowing tended to decrease root yield of soybeans.
Intervention effect Deep plowing had little effect on root yield of cabbage.
Association Root yields of plants decreased with depth on soil rototilled to 20 cm or moldboard plowed to 90 cm.

Method / resource Top-root ratios are better indicators of root activity than top or root yields alone.
Observation Sr 85 uptake showed that roots in the 70 to 90 cm zone were as active as roots in the 0 to 20 cm zone.
Intervention effect Na2CO3 tended to increase root weights in its zone of application.
