Early-blooming pollinator almond varieties treated with ethephon in November bloomed 2 to 6 days later the following spring, resulting in improved bloom overlap the next spring with later blooming varieties.
Cost efficiencies of large-scale integrated dairy production and waste management systems
by Scott C. Matulich , Hoy F. Carman , Harold O. Carter
Waste-management practices in Chino Basin dairies have sometimes been inconsistent with stringent environmental quality regulations. The impact of waste management on costs is examined by calculating costs for least-cost dairies excluding waste management.

Evaluation of crown planting and direct seeding of asparagus after 15 years
by Brian L. Benson , G. C. Hanna , Frank H. Takatori
No differences in spear yield and quality were found between directseeded and crown-planted asparagus after 6 years. The number of viable crowns appears t o be more important than crown area in relation to spear yield.
