+31% potato yield, 76,275 vs 58,035 kg/ha
Request a QuoteA commercial potato grower in Shandong, China wanted to increase tuber yield and improve crop uniformity without overhauling the existing fertility program. The trial evaluated whether an ABI microbial consortium, a multi-strain blend of beneficial bacteria and fungi, could strengthen root development and nutrient efficiency enough to move marketable yield. The consortium was applied twice at 45 g/ha (50 billion CFU/g) on a field transplanted February 1 at 48,000 plants per hectare, with harvest on May 7.
The untreated control field yielded 58,035 kg/ha. Side-by-side trial photos show control potatoes were smaller and less uniform than those from the treated plot. In commercial potato production, that size variability hurts packout consistency and cuts returns per hectare, since buyers pay premiums for uniform, graded tubers.
The treated field yielded 76,275 kg/ha, a gain of 18,240 kg/ha and a 31.43% increase over the control. Treated potatoes were also visibly larger and more uniform, pointing to stronger crop performance and better marketability at packout. The result is consistent with what a well-colonized root zone contributes to tuber development: improved nutrient cycling, root stimulation, and more balanced microbial activity.
Built from beneficial bacteria and fungi that ABI manufactures in its own U.S. fermentation facility, including multiple Bacillus and Trichoderma species alongside Brevibacillus, Aspergillus, and Penicillium, each DNA-verified for identity and purity. Explore our strains.
