Forage Projects

Evaluation of Forage Plantain

Principle Investigator: David Lile, County Director/Farm Advisor, Lassen County, Susanville; Steve Orloff, County Director/Farm Advisor, Siskiyou County, Yreka.

Plantain

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.

731

  • 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.

Kuraclover

  • 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.

767

  • 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

784 2016

  • 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.
