A few years ago, we started including salt includer and salt excluder scores in the Stine Seed Catalog, which has prompted growers to ask about the difference between the two scores. The easiest way to explain is to differentiate the characteristics between salt includer and salt excluder soybeans.
A salt includer is a “normal” soybean. These soybeans will quickly translocate salt or chloride to the top portion of the plant or the new growing points. This typically causes chlorosis or yellowing and often stops plants from growing, which leads to stunting and reduced yield.
Salt excluder soybeans have a gene that enables them to segregate and exude the chloride to keep the plant from stunting and causing reduced yields. This is important in areas where salty irrigation water is used or near the coasts. It can also be beneficial in soils that are considered sodic or have spots of high salinity that tend to cause stunting and chlorosis of soybeans.
While the majority of soybeans in our 2019 lineup are salt includers, we do have a number of options available for growers who need salt excluder soybeans. Ask your Stine sales rep to show you the lines we have available in our Stine® GT27™, LibertyLink® GT27, Enlist E3™, Roundup Ready 2 Xtend® and Roundup Ready 2 Yield® trait packages.
