Abstract
Several fertilizer formulations were placed with the seed of Rocket flax at various rates to observe their effects on emergence.In field tests, 20 pounds of nitrogen per acre placed with the seed significantly reduced emergence. When broadcast, 80 pounds caused no reduction in stand, and yields were increased. Whenever the fertilizer treatments reduced the stand of flax to 43 plants per foot of row or less, yields were reduced. This number of plants corresponds to a seeding rate of approximately 36 pounds per acre.In greenhouse tests it was generally safe to apply up to 15 pounds of nitrogen with flax seed if soil moisture was adequate. P 2 O 5 in the form of mono-ammonium phosphate could be safely applied at rates from 5 to 20 pounds, depending on the N:P 2 O 5 analysis of the fertilizer. The greater the amount of N in the fertilizer, the less P 2 O 5 could be used. Results with mono-calcium phosphate were more erratic and generally less satisfactory than with mono-ammonium phosphate. The former could not be used safely at rates above 15 pounds P 2 O 5 per acre.Damage to flax from commercial fertilizers was greater when the moisture content of the soil was low. The results indicated that fertilizers at normal rates should not be applied in close contact with flax seed unless there is adequate moisture for germination and growth.
