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

Naturamin WSP

Type: Protein hydrolysate, Company: Daymsa

Effect

Increased produce quality

Naturamin WSP treated Barley grain, 3 different var. of Hordeum vulgare L., grown in both a conventional as an organic system had on average more phenolic acids with 34 % significant more GA (gallic acid), 14 % significant more DHBA, 16.2 % significant more HBA, 10 % more PCA (not significant), 5.6 % more SYA (not significant), more phenolic acids with 6.4 % more p-CA, 28 % significant more CGA, 248 % significant more CA, no difference in A, 39.8 % significant more FA, more flavonoids with 25.1 % significant more NGN, 23.4 % significant more VIT, no difference in VIT, QU, 15.3 % significant more API, 23.5 % significant more KPF, 13.5 % significant more LU, 74.4 % significant less chlorophyll a, 600 % significant more chlorophyll b, 25.3 % significant more Dph, 42.3 % significant less Lut, 282.4 % significant more PhM, 6.6 % significant less ABTS+ compared to the untreated control grown under the same conditions. Best results under organically cultivation on in particular the orginal black-grained genotypes
