Effect
Increased nitrogen N use efficiency
Increased water use efficiency
Increased yield
Kelpstar treated Sweet Basil, soil-grown in a greenhouse under drought conditions and different nutrient levels resulted in a 17.4% higher yield (sign), more dry matter (+2.6%), a higher total leaf area (+6.5%), a 10.4% higher stomatal conductance (sign), a 15.7% higher water productivity (sign), a 1.9% higher specific leaf area, 2.3% more chlorophyll (sign), a 13.8% higher NUE (sign), a 3.3% higher nitrate content (sign), 14.1% more phenolics (sign) and 28.2% more ascorbic acid content (sign) compared to the untreated control treatment.
