USDA-NASS OKLAHOMA FIELD OFFICE OKLAHOMA WHEAT ESTIMATING PROGRAM 2012 CROP YEAR JUNE 2012 The USDA’s National Agricultural Statistics Service program for wheat in-cludes a number of estimates that are made on a schedule spanning the en-tire crop year. The inclusion of any state in the national program is depend-ent on that state’s portion of the national wheat crop. Oklahoma compiles estimates for acreage, yield, total production, prices, and planted variety for winter wheat. Crop progress and conditions are also tracked throughout the year and grain stock estimates are compiled quarterly for wheat. The survey data used to estimate wheat come from a series of probability and non-probability surveys conducted throughout the year. A general de-scription of a probability survey is one for which every farming operation has a known probability of being selected and when selected, represents a known number of similar operations throughout the state. Probability sur-veys produce not only indications for a particular category, but an estimated sampling error associated with each of those indications. Survey information is gathered volun-tarily from wheat growers across the state of Oklahoma, except for the price data, which is col-lected from grain elevators. All individual data collected through any of these surveys are held in the strictest confidence and are used only in combination with other reports to generate state and county level estimates. The crop year for wheat estimates begins in December when producers report the acres they planted in the fall. In May, the first harvested acreage forecast is set. Planted and harvested acreage is then reviewed using survey data collected in June, with the end-of-year estimates be-ing published in late September. Yield per acre estimates are based on both data reported by producers, as well as data collected from field observations. Monthly probability yield surveys, conducted from May through August, collect information from producers about their expected yields. Another monthly probability sur-vey, Wheat Objective Yield, collects field observations for winter wheat. Small plots are laid out in about 180 randomly selected fields across the state. Counts are made and clippings are taken for analysis up through harvest. Gross yield per acre and post harvest loss are combined to de-termine an indication of net yield per acre. Winter wheat crop progress and conditions are collected and published on a weekly basis throughout most of the year along with selected weather data. Stocks on hand are estimated four times a year for all wheat. Prices received by farmers are estimated monthly and are then used to de-rive a market-year average price. County level estimates for acre-age, yield, and production are prepared in the Fall after the Annual Small Grains Summary. Data for the county estimates come from a combination of all the above-mentioned survey data, as well as a very large end-of-the-year acreage and production survey conducted in August after harvest.
