Sunflower produces good yields

The above normal rainfall we have seen this growing season has helped to contribute to some good sunflower yields.

Last week I collected data from a Sunflower Hybrid Test conducted with Allen and Ross Moench of Agua Dulce. Four oilseed hybrids were evaluated in a replicated test planted on March 13, 2010, and harvested July 14, 2010 with a John Deere Combine and weighed with an electronic weigh wagon.

Yield results from the test were:

• Pioneer 63M91 at 2,095 pounds per acre

• Syngenta 3731 at 2,030 pounds per acre, and

• Triumph 678 at 1,854 pounds per acre

When the data were analyzed, there was not a statistical difference between these three hybrids. Croplan 378 produced a yield of 1,554 pounds per acre, but had a significantly lower plant population, which certainly had an impact on yield.

Bushel weights in the test ranged from 28 to 34 pounds, while the entire test yield averaged 1,883 pounds per acre. A detailed report will be available soon from the Nueces County Extension Office.

The support of Allen and Ross Moench for cooperating with this test is appreciated.
