Results from two cotton variety trials in Nueces County, including yield and lint quality data are complete and the good yields are reflective of the good growing conditions that we had in 2010. Recently cotton prices have moved well above $1 per pound and this should increase the acreage for the 2011 crop in the Coastal Bend. Selecting the best suited variety for your farm remains one of the most important early decisions you can make as you plan for next year’s crop.
A Uniformed Stacked-Gene Variety Trial was conducted with Jim Massey IV, just northeast of Petronila. The plots were planted on March 27 with three replicates per variety in a randomized complete block design on 30-inch rows. This dryland test was harvested by machine on August 27, 2010. There were ten varieties in the test. The test averaged just over 1,263 pounds of seed cotton per acre. The best two performing varieties (no statistical difference between the two) were FiberMax 1740 B2F at 1,446 pounds per acre with a loan value of $0.537 per pound and DeltaPine 0920 B2RF at 1,403 pounds per acre with a loan value of $0.5118 per pound.Other varieties in this test and their yields were as follows; ST 5458 B2RF @ 1,315 lbs./ac, PHY 367 WRF @ 1,280 lbs./ac, ST 4288 B2RF @ 1,251 lbs./ac, PHY 375 WRF @ 1,231 lbs./ac, CL 3220 B2RF @ 1,208 lbs./ac, DP 1032 B2RF @ 1,186 lbs./ac, FM 9160 B2F @ 1,167 lbs./ac, and AT Apex B2RF @ 1,150 lbs./ac. Overall the lint values per acre of this test (using the loan value) ranged from $616.70 to $776.30 per acre.
A Liberty Link Cotton Variety Trial was conducted with Darrell Lawhon, east of Bishop. The plots were planted on March 26 with three replicates per variety in a randomized complete block design on 38-inch rows. This dryland test was harvested on August 17, 2010 by machine.
There were six varieties in this test that averaged more than 1,140 pounds of seed cotton per acre.
The best two performing varieties (no statistical difference between the two) were FiberMax 1845 LLB2 at 1,269 pounds per acre with a loan value of $0.5198 per pound and FiberMax 835 LLB2 at 1,223 pounds per acre with a loan value of $0.5418 per pound.
Other varieties in this test and their yields were as follows; FM 1015 LLB2 @ 1,122 lbs./ac, FM 1035 LLB2 @ 1,094 lbs./ac, FM 1025 LLB2 @ 1,076 lbs./ac, and FM 1773 LLB2 @ 1,059 lbs./ac. Overall the lint values per acre of this test (using the loan value) ranged from $544 to $659.70 per acre.
These tests would not possible without the cooperation and support of local farmers and various seed companies, and for that we should all be grateful.
