| dc.description | A study was conducted on the Texas A & M Plantation near College
Station, Texas, from April 1966 to October 1966, to evaluate the response
of blue panicgrass, Panicum antidotale Retz., to frequency of
clipping and nitrogen fertilizer.
Plants were subjected to 3 frequencies of clipping (3, 6, and 9
weeks) and 4 levels of nitrogen fertilizer (0, 50, 150, and 250 pounds
per acre of nitrogen as ammonium sulfate) in all combinations.
Largest production of forage was experienced with a 9-week, frequency
of clipping and 150 pounds of nitrogen fertilizer, but protein
content was lower with the 9-week frequency. The change in yield with
fertilization was. not as great as expected in a plant which is believed
to require heavy fertilization. Small effects of nitrogen on production
of herbage were obtained with frequent harvest; whereas, with mild
and late harvests, the higher levels of nitrogen doubled production. | |
