Wheat growers may see good yields, even planting older varietieKansas This year's weather extremes resulted in a shortage of high quality wheat seed in some areas. That does not necessarily mean producers will also see lower yields, a Kansas State University agronomist said. "With the shortage of good quality wheat seed of newer varieties in parts of central and eastern Kansas this year, producers may have to use some older varieties that have lost their leaf rust resistance," said K-State Research and Extension state agronomy leader Jim Shroyer. "If those producers are ready to treat the older varieties with a foliar fungicide next spring, will they have to settle for a lower yield potential? All else being equal, probably not." Varieties such as 2137, Jagalene, Jagger and Karl 92 still have good to excellent yield potential, if treated in a timely manner when disease pressure makes that necessary, Shroyer said. Other factors such as freeze injury, heat, drought, flooding, and hail can still limit the older varieties' yields. But, those factors can reduce the yields of almost any variety, new or old. "In general, producers in central and eastern Kansas do not have to worry about settling for low yields by using 2137, Jagalene, Jagger, or Karl 92--provided they treat these varieties with a foliar fungicide, if necessary. In the absence of leaf diseases, these varieties can still be reasonably competitive with the newer varieties," the agronomist said. B 9 9/24/07 2 Star EK Date: 9/20/07 Advertisement
