4.6% Higher Tomato Yield With a 2-Point Higher Soil Quality Score
At Bogmisan Bog Farm in Jirakh, Uzbekistan, the Kyminasi® Crop Booster™ tomato treatment produced 38.7 t/ha compared with 37 t/ha in the control. The treated plot also recorded a soil quality score of 49 compared with 47 in the control.

Crop Booster produced 1.7 additional tons of tomatoes per hectare.
Tomato yield increased from 37 t/ha in the control to 38.7 t/ha in the Crop Booster plot. This is an absolute increase of 1.7 t/ha and a calculated relative increase of approximately 4.59%, consistent with the source-reported 4.6%.
Higher Tomato Yield
Crop Booster-treated tomatoes produced 38.7 t/ha compared with 37 t/ha in the control plot.
Higher Soil Quality Score
The treated plot recorded a soil quality score of 49 compared with 47 in the control, an absolute difference of 2 points.
17 Harvest Cycles
Both the Crop Booster and control plots completed approximately 17 harvest cycles during the August–September window.
Same Harvest Count
Harvest-cycle count was the same in both plots, so the measured yield difference was not accompanied by an increase in the reported number of harvest cycles.

The supplied trial reports tomato yield of 37 t/ha in the control and 38.7 t/ha in the Crop Booster treatment. These raw values produce an absolute increase of 1.7 t/ha and a calculated relative increase of approximately 4.59%, consistent with the source-reported 4.6%. The soil quality score increased from 47 to 49, an absolute difference of 2 points. Although this is numerically equivalent to approximately a 4.26% increase relative to the control score, the scoring scale, parameters included, weighting system, testing method, and interpretation thresholds are not supplied. Therefore, the result is presented primarily as a 47-to-49 score change rather than as a quantified percentage improvement in overall soil health. Both plots reportedly completed approximately 17 harvest cycles during the August–September period. No individual harvest weights, fruit count, fruit size, Brix, tomato grade, plant height, biomass, fertilizer-use comparison, pesticide-use comparison, irrigation-volume comparison, soil laboratory values, production costs, revenue, or economic-return data were supplied.
Why this matters for tomato growers: This Uzbekistan field trial provides a direct yield comparison under the same reported harvest count. Crop Booster tomatoes produced 38.7 t/ha compared with 37 t/ha in the control, while the soil quality score was also 2 points higher in the treated plot.
