12—Lancaster Farming, Saturday, Feb. 9, 1974 Hartwig Suggests . . . Double Double planting of corn and crownvetch is suggested for farmers wanting to harvest com while starting crownvetch as a perennial sod cover for continuous no tillage com. The crownvetch can be broadcast at com planting time, says Dr. Nathan L. Hartwig, assistant professor of weed science at The Pennsyvlama State University. Hartwig reports a number of fanners have been in terested in growing crownvetch for seed. Broadcast-seeding at time of planting com should use 5 pounds of inoculated seed per acre. Crownvetch can also be applied in a band over the row, from a planter insecticide box, using 5 pounds of seed per acre in the band. In fields of established crownvetch, yields of com can be high. Yields averaged 165 buushels of shelled com per acre this past season at Penn State’s Agronomy Research Farm in Centre County. The com plots were fertilized with only 94 pounds of nitrogen per acre, 14 pounds of superphosphate, and 14 pounds of potash. The fields were irrigated twice THE MOST NEW FEATURES IN MORE NEW MOD '• •'' / 130 MODELS 12 TO 48 FOOT DIAMETER BINS CAPACITY FROM 1700 TO 75,000 BUSHELS SEE US FOR COMPLETE DESIGN & LAYOUT TAILORED TO FIT YOUR NEEDS ORDER NOW TO EARN EARLY ORDER DISCOUNT. e'-I 5.

Weed killers must be chosen carefully to avoid injury to crownvetch Chester County Holds Annual DHIA Banquet More than 240 members and guests convened for the annual Chester County Dairy Herd Improvement Association banquet last Thursday evening at the Guthridgeville Fire Hall. Also attending were five DHIA supervisors, Peter Emig, head of the Penn State milk testing lab, and Herb Gilmore, a Penn State dairy specialist. John Stanton, Lincoln University, is president of the Chester County group. Elmer Young, West Grove, is vice-president, and Paul King, Cochranville, is secretary-treasurer.

For weed control in soybeans, the herbicide trifluralin (Treflan) or vemolate (Vernam) should be used at recommended rates. A few farmers in Penn sylvania have grown crownvetch as a seed crop for a number of years, Hartwig observes. Where these farmers want to grow com and crownvetch, the crownvetch can almost be disregarded in using weed killers. Established crownvetch tolerates all herbicides that are cleared for use on no-tillage corn. Research at Penn State has shown that up to 4 pounds of atrazine or simazine can be applied in any one growing season without killing crownvetch.

Since crownvetch is a legume it will fix nitrogen from the atmosphere into the 4oil. This can be a vital factor, Hartwig says, in light of the high cost and probable shortage of nitrogen fer tilizer next year and possibly for years to come.
