UCCE Rice Yield Contest

Purpose

UCCE Rice Yield Contest

The purpose of the California Rice Yield Contest is to provide an opportunity for rice producers and UC scientists to share information about intensive rice production in California and to recognize individuals who have achieved the highest yields in the state. Please read the rules carefully.

2016 Contest Winners

2016 Rice Yield Contest Winners

In 2015 University of California Cooperative Extension (UCCE) initiated the UCCE Rice Yield Contest as a pilot study in Butte county. Due to the success of the pilot study, in 2016 the contest was expanded to include all of Sacramento Valley.Due to possible yield potential differences, the valley was divided up into 4 regions (1-NE, 2-NW, 3-SW, and 4-SE) using Hwy 20 and the Sacramento River as dividing lines.

Harvest and weighing were closely monitored by UCCE personnel. Yields are determined from a minimum of 3 acres from a 10-acre test plot and reported at 14% moisture. In 2016 there were roughly 20 yield contest entries; however, due to the early rains which interrupted harvest activities, we were only able to monitor six yield contests (from 3 regions).

2016 winners were Josh Sheppard, Steve Willey and Joe Richter. READ MORE...

In 2015, the University of California Cooperative Extension (UCCE) initiated a yield contest with rice growers. The purpose of the contest is to provide an opportunity for rice producers and UC scientists to share information about intensive rice production in California and to recognize individuals who have achieved the highest yields in the state. The contest is modeled after the National Corn Yield Contest with some modifications. We required a minimum field size of 20 ac within which a 10 ac contiguous rectangular portion was selected by the grower as the contest plot. From the contest plot a minimum of 3 acres had to be harvested with the combine skipping 3 passes between each harvest pass. This ensured that that the contest plot was adequately sub-sampled and left enough harvestable area in case a retest was required. UCCE supervisors monitored the whole test ensuring combines, bank-out wagons, and trailers were empty before harvesting the test plot. In addition, they measured the harvest area with tapes and measuring wheels. The supervisors went with the trailer to a certified drier where the rice was weighed and moisture taken. Yields (adjusted to 14% moisture) were determined based on these measurements and if yields exceeded 120 cwt, a recheck was done. Final yields also accounted for dockage. READ MORE...
