Turmeric yield doubled from the historical 8 ounces to 16 ounces per plant.

The Crop Booster-treated turmeric produced 16 ounces per plant compared with the historical average of 8 ounces per plant, a 100% increase. After 90 days, treated plants reached 60 inches tall compared with the historical 24-inch height, a difference of 36 inches or 150%.

The supplied case reports that Crop Booster-treated turmeric plants reached 60 inches tall after 90 days, while the historical turmeric height at this location was 24 inches. The difference is 36 inches, and 36 ÷ 24 × 100 equals a 150% increase relative to the historical height. The source also reports historical turmeric yield of 8 ounces per plant compared with 16 ounces per plant using Crop Booster. This is an absolute increase of 8 ounces per plant and a mathematically correct 100% increase. Although the narrative states that accelerated growth, thicker stems and greater plant health were observed compared with control plants, no numerical control height, control yield, stem-diameter measurements, plant-health scores, sample sizes or statistical analysis are supplied. Therefore, the 60-inch and 16-ounce results are presented against the historical baselines supplied in the case rather than as measured simultaneous control differences. The qualitative growth, stem and plant-health observations are retained as source-reported observations. No total yield per greenhouse or acre, rhizome count, fertilizer use, pesticide use, irrigation volume, production costs, revenue or economic-return data were supplied.

Why this matters for turmeric growers: This Puerto Rico greenhouse case documents a substantial difference from the location's historical turmeric performance. Yield increased from a reported historical 8 ounces to 16 ounces per plant, while treated plants reached 60 inches compared with the historical 24-inch plant height.
