- Cornell University Organic Crop Production Guides. These Organic Production Guides outline general practices for growing vegetable crops using organic integrated pest management techniques. The guides provide an overall approach for organic production with a focus on biological, mechanical, and cultural controls. Sections on cover crops, resistant varieties, crop rotation, field selection, soil quality and nutrient management all highlight their interrelated qualities and precede specifics on pest management options.

Grafting in Vegetable Production
For a more complete list of information resources on vegetable grafting, see Grafting Vegetables at WSU’s Vegetable Research and Extension.
Vegetable Seed Sources
Conventional and organic seed sources.
- USDA Crop Profiles
- USDA National Agricultural Statistics Service (USDA NASS). National level data on vegetables can be found by clicking on the “Crops and Plants” link and then clicking on vegetables at Step 1 under the “Browse NASS by Subject” area.
- State offices of USDA’s National Agricultural Statistics Service can be reached by selecting a state in the gray box on the left. For statistics on vegetable crops by state, first select a state. On the resulting state page, select “State – Vegetables” and click “Go”. Then on the “Vegetables” page select the data type, vegetable, and years of interest. Data can be downloaded as well as viewed online.

WA State Department of Agriculture
Washington State University’s AgWeatherNet. AgWeatherNet (AWN) provides access to raw weather data from the Washington State University weather network, along with decision aids. AWN includes 134 weather stations located mostly in the irrigated regions of eastern Washington State but the network has undergone significant expansion in Western Washington and in dry land regions of the state. The AWN network is administered and managed by the AgWeatherNet team located at the WSU Irrigated Agriculture Research and Extension Center in Prosser, WA but is programmatically linked to efforts at other WSU research and extension centers.
Evapotranspiration Forecasts from the National Weather Service
Evapotranspiration (ET) forecasts, which are used for irrigation scheduling, are available from the National Weather Service (NWS) internet site at http://www.weather.gov/Pendleton. Click on “Graphical Forecasts”. Forecasts will be made for up to seven days and include departure from normal. The ET forecast is for alfalfa. Forecasts are updated daily at 5 a.m. from March 15 to October 15 by meteorologists at the NWS in Pendleton Oregon.
The ET forecast is calculated using the 1982 Kimberly-Penman model, and is based upon local conditions for temperature, humidity, wind speed, and cloud cover. Solar radiation is then derived from cloud cover based upon the time of year. The output is a reference ET forecast for alfalfa. To use the ET forecast for other crops, a conversion must be made based upon that crops growth stage. This can be done by checking the U.S. Bureau of Reclamation’s Agrimet information at www.usbr.gov/pn/agrimet.
