41% more marketable yield and about $572 in added gross revenue per harvest, in a commercial greenhouse in Queretaro, Mexico.
Request a QuoteA commercial tomato operation in Queretaro wanted to raise marketable greenhouse yield without changing its core agronomic program. To measure the impact of a biological input, the grower ran a side by side trial across two matched quarter hectare greenhouse blocks, each planted with 5,000 tomato plants transplanted on the same date. The treated block received the grower's standard fertility and crop care program plus the ABI microbial biofertilizer, a consortium of DNA verified beneficial bacteria and fungi, applied weekly for 12 weeks and then monthly, 17 applications in total. The control block ran the identical program with no microbial consortium. Both blocks were tracked from transplant through harvest for plant vigor and marketable weight per cut.
The untreated control block averaged 1,590 kilograms of marketable tomato per harvest. Just three weeks after transplanting the difference was already visible in the field, with the control rows carrying sparse, smaller plants and long stretches of open bed between them. In greenhouse tomato production, marketable weight per cut is the number that drives grower revenue, so a thinner stand and a lower harvest weight translate directly into lost income on every pick.
The block treated with the ABI microbial biofertilizer averaged 2,250 kilograms of marketable tomato per harvest, 41% more than the untreated control, a gain of 660 kilograms per cut. At the grower's price that added about 10,560 pesos, roughly 572 US dollars, in gross revenue on every harvest. The advantage showed up early and held through the season, with treated rows forming a full, uniform canopy by week three while the control stayed sparse. Because both blocks were transplanted on the same day and ran the same fertility and crop care program, with the microbial consortium as the only difference, the yield gain is cleanly attributable to the treatment.
The treated block was inoculated with the ABI microbial biofertilizer, a consortium of DNA verified beneficial bacteria and fungi manufactured and fermented in the United States, including Bacillus, Pseudomonas, and Trichoderma species selected to support nutrient cycling and root development.
