“…Oil content of non-oven dried seed was determined by solvent extraction after rupture of the seed coat (Comstock & Culbertson, 1958). Plants were washed to remove traces of soil and the total number of shoots recorded before being separated into their leaf, stem, root and, when present, capsule components.…”

Meadowfoam (Limnanthes alba Benth.) seed is a source of oil for use in industrial products and processes. Nitrogen fertilization typically has not increased seed yields of meadowfoam. Data are lacking for characterizing plant growth responses, flowering, honey bee (Apis mellifera L.) foraging, oil yield, and yield components of meadowfoam when fertilized with N. Thus, this field study was conducted in 1981 and 1982 on a Woodburn silt loam soil (fine-silty, mixed, mesic Aquultic Argixeroll) to determine the effects of ammonium sulfate applied at 0 (control), 50 (SON), and 100 (lOON) kg N ha-•. Increased vegetative growth of meadowfoam in response to spring application of N appears to be consistent. Nitrogen fertilization lowered canopy light transmittance and caused a differential flowering response from nonfertilized plants. Seeds per flower in the N-fertilized treatments were not increased. Flower densities inN-fertilized treatments in 1982 averaged 135% higher than in the control. Seed yields were not increased by N in 1981, but in 1982, seed and oil yields were increased by 113 and 99%, respectively, when N was applied. Oil content was consistently lower when N was applied, but this effect was more than offset by the higher seed yield in 1982. Because of the similar response of agronomic characters in SON and lOON treatments, applications of 100 kg N ha-• do not appear to be advantageous. Spring N fertilization of meadowfoam increased seed yield primarily through increased flower number.

“…At maturity the seed from the primary, secondary, and tertiary heads in each subplot was harvested and analyzed separately for oil content and quality of the oil. Oil content was determined on duplicate samples, each of 200 seeds, using the method described by Comstock and Culbertson ( 2). Quality of oil in terms of its iodine value and fatty acid composition was determined as follows: from each seed sample pressed a sufficient amount of oil was collected with a medicine dropper to supply 5 drops for the iodine value determination and 1 drop for the preparation of methyl esters of the fatty acids as described by Yermanos and Knowles (14).…”
