Evaluation of Forage Plantain
Principle Investigator: David Lile, County Director/Farm Advisor, Lassen County, Susanville; Steve Orloff, County Director/Farm Advisor, Siskiyou County, Yreka.
To compare stand establishment, persistence, and production of two varieties of plantain, two varieities of chicory, and Kura clover in comparison with Ladino clover.
- To determine seasonal forage quality and mineral nutrient availability.
- To assess practicality of tested varieties as potential forages in intermountain irrigated pasture systems.
Investigation of Indaziflam for Invasive Annual Grass Control and Perennial Grass Establishment
Principle Investigator: Tom Getts, Weed Ecology & Cropping Systems Advisor, Lassen County, Susanville.
- To determine effectiveness of invasive annual grass control after indaziflam and aminocyclopyrachlor application.
- To assess secondary weed invasion after annual grass herbicide applications.
- To determine perennial species herbicide tolerance, and establishment potential.
Kura Clover Project
Principle Investigator: Dan Putnam, Extension Agronomist, Dept. of Plant Science, UC Davis; Steve Orloff, UCCE, Siskiyou Co.; Charlie Brummer, UC Davis; N. Ehlke, C. Sheaffer, Univ. Minnesota; Oli Bacchi, UCCE, El Centro; Chris DeBen, UC Davis; Khaled Bali, UCCE El Centro.
- To determine preliminary seed and forage yield possibilities at 3 different locations in California.
Assessing Efficacy of Zinc Phosphide-Coated Cabbage for Belding’s Ground Squirrel Control
Principle Investigator: Roger Baldwin, Vertebrate Pest IPM Advisor, Kearny Agricultural Center; Steve Orloff, County Director/Farm Advisor, Siskiyou County, Yreka.
- To determine efficacy of zinc phosphide cabbage bait using different mixing strategies.
- To determine what species consume bait.
- To determine peak time of day for bait consumption.
- To assess cost for bait application.
Influence of Fall Defoliation Height on the Productivity of Three Perennial Grasses
Principle Investigator: Steve Orloff, County Director/Farm Advisor, Siskiyou County, Yreka; David Lile, County Director/Farm Advisor, Lassen County, Susanville
- Compare the yield potential of the three most commonly grown perennial grass species in the Intermountain Region.
- Evaluate the effect of three different fall herbage heights on the subsequent growth of tall fescue, orchardgrass and Timothy.
- Determine the effect of fall herbage height on water soluble carbohydrates the following spring and determine the relationship between water soluble carbohydrates and pasture growth.
- Estimate the biomass and nutritive value of fall/winter harvested forage of each treatment (using #1 as benchmark) to demonstrate how much fall forage producers would have to forego to implement higher stubble-height management strategy.
