Example, to search for all recorded cases of biostimulant use on tomato mitigate effects of drought type: "tomato, drought"

Fulvagra

Type: Mix of different types, Company: Humintech GMBH

Effect

Increased produce quality
Increased nitrogen N use efficiency
Increased phosphorous P use efficiency
Increased potassium K use efficiency
Increased micronutrient use efficiency
Increased yield
Increased salt stress tolerance

Fulvagra® treated Cherry tomato, Solanum lycopersicum var. cerasiforme L., grown in a fertile soil were significant taller, had a significant bigger stem diameter, significant more leafs, a significant higher shoot and root dry weight, a significant higher chlorophyll content, significant mor clusters per plant and fruits per cluster, a significant higher cluster and fruit weight, a significant bigger fruit diameter and width, no difference in yield, fruit dry matter, fruits had a significant higher total soluble solids content, no difference in vitamine C content, had significant more N%, P%, K%, Na% and Ca% in roots, shoots and fruits and had an increased antioxidant activity compared to the untreated control grown in the same fertile soil. Fulvagra® treated Cherry tomato, Solanum lycopersicum var. cerasiforme L., grown in a stressed soil with salt stress were significant taller, had a significant bigger stem diameter, had significant more leafs, had a significant higher shoot and root dry weight, had a higher chlorophyll content, had significant more clusters/plant and fruits/cluster, had a significant higher cluster and fruit weight, had a significant bigger fruit diameter and width, had a significant higher yield and higher fruit dry matter, fruits had no difference in total soluble solids but a significant higher vitamine C content, had a significant higher N%, P%, K%, Na% and Ca% content in roots, shoots and fruits, and had a significant higher antioxidant enzyme activity compared to the control grown in the same stressed soil.
