Today we are going to be talking about the irrigation of soybeans and the late season planting production. A lot of crop has been planted. We probably had the best start to the year for planting progress. We’re about 90, a little over 90 percent planted. A lot of the crops have been planted in two to three weeks earlier than typically, so a lot of the crops that we do have in the state right now are getting close to needing some irrigation.

A lot of the crops range from just being planted as you can see behind me, to crops that are around R-3, so a good majority of acreage in the state is getting close to reproductive, where we start to really needing irrigation. 

Soybean crops, once we get to reproductive phases, use anywhere from a quarter to a third of an inch of water per day and with the conditions we have had the last several weeks, the wind we’ve had, the hot conditions, we’re using quite a bit of moisture, so we really need to start pulling those poly pipes out and think about starting to irrigate some of these early planted soybeans. 

With the conditions we have right now, I know a lot of guys did get some rainfall, so we do have some moisture in the soil right now. Other locations in the state are still fairly dry, so we really need to kind of hold off until we get some moisture in the soil to plant those beans. 

On varieties, variety testing has shown that late maturity group 4’s and up to mid-5’s perform the best in double-crop or late-planted cropping situations, so we need to be looking at those varieties on planting our late planted or double crop situation. 

As I mentioned, we’re about 10 percent of the crop to go and so we really need to try to get that in within the next two to three weeks to try to maximize yields for 2012.

For more information on these topics, you can find us at or contact your local county extension office.  Thank you. [University of Arkansas Division of Agriculture Research and Extension University of Arkansas System, Arkansas Soybean Promotion Board.]
