Foliar fertilizers such as Optimize+, Vigor Plus, 10-10-10 Premier Gro, and Prime Micro Cu (Copper) are fertilizer amendments composed of plant based sources. As such, their formulation is based on amino acid chains (peptides) that facilitate penetration into foliar tissue and guaranty greater plant nutrition absorption.
In pea, test weight (P=0.2085) was the same among treatments and thus there was no difference in comparison to the control. In contrast yield was greater in the control and in treatment 2, and lower in treatment 3 (P=0.0387).
In wheat, there was no difference between treatments compared to the control in test weight and yield (P=0.1679 and P=0.4639 respectively).
