In an evaluation of potential oilseed crops, fennel ( Foeniculum vulgare L.) was planted at Lincoln, Nebraska, on three dates and at three row‐spacings. Yields from the two earliest dates averaged 518 lb/acre, compared with 102 lb/acre for the latest date. Differences in yields for the row‐spacings were not statistically significant, nor was there interaction between dates and row‐spacings. Oil content of the seed varied from 10.7 to 19.0% for all plantings, the significantly higher amounts occurring in seed from the earliest plantings. The amount of petroselinic acid present as C 18 monoenes was found by ozonization of the mixed methyl esters, reduction to aldehydes, and consequent GLC analysis; the amount ranged from 70.0舑74.5% of the oil and was not significantly affected by either planting date or row‐spacing.
