“…Seed oil concentration was not affected by the fertilizer treatments. In the only other reports of N applications on meadowfoam production, seed yield and seed oil concentration were reduced when fertilizer was applied at 80 kg ha 21 or more in late February compared with no fertilizer applied (Jolliff et al, 1993a(Jolliff et al, , 1993b. Nitrogen application amounts .80 kg ha 21 may cause excessive vegetative growth that adversely affects the yield components (Jolliff et al, 1993b).…”

Conservation Practices in Western Oregon Perennial Grass Seed Systems:I. Impacts of Direct Seeding and Maximal Residue Management on Production

Rapid changes in practices used to produce perennial grass seed crops in the U.S. Pacific Northwest region and shortened lengths of time that perennial grass seed fields remain in production have increased the need for additional rotation crops that are adapted to the poorly drained soils found in western Oregon. This research was conducted at three sites to determine ways to manage meadowfoam (Limnanthes alba Hartw. ex Benth.) as a component in perennial grass seed rotation systems. Experiments were conducted in 1997, 1998, and 2001 to investigate combinations of spring-applied herbicide and N fertilizer and times of applications, direct-seeded and conventional tillage establishment methods, and previous crop residue management on meadowfoam seed yield, seed oil concentration, and oil yield. No spring-applied fertilizer or herbicide produced responses for all yield components as great as or greater than any other treatment combination. Direct-seeded meadowfoam yielded more oil than the conventional establishment treatment. There was no effect of residue management amounts from grass seed grown in the previous rotation sequence on meadowfoam production; however, maximal residue management, especially if used in combination with direct-seeded meadowfoam, should reduce annual soil erosion. Meadowfoam is suited to low-input production and is adapted to the use of conservation practices including direct seeding and maximal residue management in perennial grass seed systems.

“…The higher dry matter production and seed yield of meadowfoam for burned treatment in the present study, however, could be also attributed to differences in stand density, because burning increased the number of plants established. Recent investigations have indicated a positive linear response of meadowfoam seed and oil yield with seeding rates (Jolliff et al, 1993). Burning the stubble had no effects on performance of spring pea, presumably because pea is relatively insensitive to cool soil temperatures in spring.…”

Viability of alternative crops in a monoculture grass seed cropping system will be enhanced if minimum tillage establishment through grass seed stubble is successful without burning. Our objective was to compare agronomic performances of red clover (Trifolium pratense L.), white clover (T. repens L.), meadowfoam (Limnanthes alba L.), and pea (Pisum sativum L.) when drill‐seeded in the stubble of a third‐year perennial ryegrass (Lolium perenne L.) seed crop, with and without burning stubble. Four field experiments were conducted during a 6‐yr period on a Woodburn silt‐loam (fine‐silty, mixed, mesic Aquultic Argixerolls) soil in western Oregon. Ryegrass stubble was either propane‐burned or was not burned before drill‐seeding the rotational crops. In one experiment, a rotary strip‐till drill was also compared with a no‐till drill for establishing white clover in perennial ryegrass stubble. Burning the stubble enhanced spring growth of red clover; however, forage and seed yields in the first crop year were 47 and 66% higher, respectively, for the nonburned than the burned treatments. There were no differences among treatments for forage and seed yields of red clover in the second crop year. Treatments did not affect dry matter or seed production of white clover and spring pea. Meadowfoam forage and seed yields were 26 and 24% lower, respectively, for the nonburned than the burned treatments. We concluded that burning stubble before seeding may be advantageous for winter annual seed crops that mature during the spring or early summer months. However, burning stubble is not beneficial, or may be disadvantageous, for crops that mature during the late summer in areas such as Oregon with a Mediterranean climate. The no‐till drill was superior to the strip‐till drill for establishing white clover in perennial ryegrass stubble regardless of stubble management method.
