Grain yield was significantly influenced (+14.5% or +10.5 bushels per acre) by phosphate addition, relative to the untreated check, but phosphate + Avail did not improve yield relative to phosphate alone (Table 2). Leaf zinc, iron and copper were not influenced by treatments and averaged 18.5, 172 and 19.5 ppm, respectively.Īt harvest, grain moisture and test weight were not affected by treatments, averaging 15.5% and 63.6 pounds per bushel, respectively. Lowest leaf manganese was found with the untreated check, Coron, and the SabrEx and Jumpstart only seed treatments (Table 2). The leaf manganese response was complex, with the phosphate + Avail application resulting in the greatest leaf manganese concentration, though not significantly greater than those found with phosphate, BioForge, and the TJ Quickroots and Jumpstart + LCO seed treatments.
Wheat flag leaf nutrient composition and grain yield as related to the treatments.Īmong the micronutrients, flag leaf boron (B) was positively affected by Coron application, as expected (Table 2), while all other leaf B levels were not different from the untreated check. Leaf K, magnesium, calcium and sulfur were not influenced by treatments and averaged 1.97%, 0.144%, 0.72% and 0.26%, respectively. Avail addition did not improve leaf N or P levels over those found with phosphate alone (Table 2). Leaf phosphorus (P) was greatest with phosphate or phosphate + Avail application, but was lowest in the untreated check, with BioForge, Coron and the SabrEx, Jumpstart + LCO and LCO only seed treatments (Table 2). Leaf N tended to be lower in the untreated check, with BioForge, and with only Jumpstart or only LCO seed treatments. No seed treatment resulted in a stand greater than the untreated check.Įvaluating wheat’s macronutrient nutrition, leaf nitrogen (N) was a bit greater with phosphate, phosphate + Avail, Coron, and the TJ QuickRoots, SabrEx and Jumpstart + LCO seed treatments (Table 2). Plant stands ranged from about 22 to 25 plants per square foot, with an average of 23.5 plants per square foot, and were not affected by treatments. Treatment materials and application timing in the wheat PEP-NBT study.
I have worked with BioForge seed treatment for about 8 years now.Table 1. I see the BioForge seed treatment gave a yield increase in both reps. There was a nice mix of products trialed. Thanks for sharing the seed treatment plot data.
