Small grain varieties were again evaluated for forage production during the 1995-96 season at the Ardmore Headquarters farm and the Red River Demonstration and Research farm near Burneyville. Two plantings were established at Ardmore on September 28 and October 18, and September 27 and October 17 at Burneyville. Three clippings were made on both plantings at each location.
In general, fall and winter forage production was limited by dry, cold weather. However, we did receive timely rainfall in March and April, and spring forage production was good to excellent. Winter damage was moderate to heavy among oat varieties and some winterkill was evident in some of the early forage producing wheats and triticales. The October planting of oats was completely taken out by winter damage at Burneyville.
At Ardmore, the total dry forage yields of the September (early) planting, ranged from 1539 to 4212 pounds/acre. In general, the wheats and triticales produced the most forage and oats the least. The top ten total forage yielders included seven wheats and three triticales. The top five forage yielders for each small grain tested along with dry pounds/acre are:
- • Triticale: (1) Presto - 4212, (2) Hartman - 3908, (3) NF11 - 3859, (4) Pika - 3717, and (5) Trical Stan I - 3629.
• Wheat: (1) 2163 - 4066, (2) Pioneer 2548 - 4035, (3) NF165 - 3943, (4) Tonkawa - 3942, and (5) Coker 9904 - 3815.
• Rye: (1) Bates - 3672, (2) Maton - 3419, (3) Bonel - 3356, (4) NF90 - 3344, and (5) Wintergrazer 70 - 3331.
• Oats: (1) Ozark - 2920, (2) NF55 - 2826, (3) NF188 - 2651, (4) Okay - 2629, and (5) 833 -2544.
This season the October (late) small grain planting produced an average of 9% less total forage than the early planting at Ardmore. This is a reversal from the previous five growing seasons. The total dry forage yields for each entry are as follows: (1) Bates rye - 3415, (2) Maton rye - 3272, (3) Longhorn wheat - 3186, (4) Oklon rye - 3150, (5) Trical 2700 triticale - 3107, (6) 833 oat - 2953, (7) 2180 wheat - 2953, (8) NF21 triticale - 2753, (9) Coker 9134 wheat - 2724, and (10) Harrison oat - 2319.
Despite the droughty fall and winter conditions, overall forage production was good to excellent at Burneyville again this season. Yields ranged from 1868 to 6531 dry pounds/acre on the early planting. The ryes generally produced the most forage throughout the growing season. The top five forage producers for each small grain are as follows:
- • Rye: (1) NF94 - 6531, (2) Bonel - 6486, (3) NF25 - 6258, (4) NF90 - 6140, and (5) Oklon - 6097.
• Wheat: (1) Longhorn - 5215, (2) 2163 - 5176, (3) Pioneer 2548 - 5132, (4) Tomahawk - 4933, and (5) Triumph 64 - 4801.
• Triticale: (1) Pika - 4724, (2) NF87 - 4712, (3) NF21 - 4656, (4) NF57 - 4650, and (5) RSI I27 - 4549.
• Oats: (1) NF55 - 3594, (2) Okay - 3584, (3) NF188 - 3489, (4) Ozark - 3256, and (5) Bob - 2876.
At Burneyville, the late planting averaged 7% less total forage production than the earlier planting. The overall average was reduced substantially in the October planting because of winter damage to the oats. The total dry forage yields for each entry are as follows: (1) Maton rye - 7163, (2) Oklon rye - 6919, (3) Bates rye - 6610, (4) Longhorn wheat - 4841, (5) NF21 triticale - 4601, (6) 2180 wheat - 4523, (7) Coker 9134 wheat - 4357, (8) Trical 2700 - 3893, (9) 833 oat - 0, and (10) Harrison oat - 0.
