Effects of Spring Planting Date and Row Spacing on the Agronomic Characteristics and Chemical Composition of Crambe
1973

Crambe (Crambe abyssinica Hochst. ex R. E. Fries) has potential as a new oilseed crop. Since crambe is not winter hardy, an experiment was conducted at Experiment, Ga. to study the effects of spring planting dates and row spacing on agronomic characteristics and chemical composition of the seed. P.I. 247310 was spring seeded in 1969 and 1970 at four 1-week intervals in three row spacings, 36, 53, and 71 cm. Seed yields were similar for all planting dates and averaged 724 kg/ha. Planting dates did not affect oil content or fatty acid composition of oil in 1969, but the earliest planting produced higher oil and erucic acid contents in 1970. Each 18-cm decrease in row width produced approximately 30% more seed. Row spacing did not affect oil content or fatty acid composition. Planting date and row spacing did not significantly affect test-weight, pod percentage, or plant height.
