Trial Name: 2020 Foliar Nitrogen Applications with Fulvic Acid

Description

This trial compares wheat subject to differing combinations of in-furrow and foliar applied nitrogen (N) and fulvic acid (FA). Yield, test weight, and protein content was assessed. The trial will be repeated in 2021 and 2022.

There were no significant differences between the measured yields (P=0.04). Similarly, all treatments (control; soil applied nitrogen + fulvic acid; soil applied nitrogen + fulvic acid AND foliar applied nitrogen + fulvic acid) exhibited test weights too similar to be regarded as different by the statistical analysis. Test weight (P=0.52) values ranged only one lb/bu, that is, between 63.5-64 lb/bu. No significant differences were found in protein content (P=0.09).
