Bio-stimulant for improved plant growth and development
A bio-stimulant composition for obtaining improved plant growth, either combined or uncombined with urea and/or other agricultural compounds, as well of methods of producing and using said composition.
1. A plant biostimulant composition effective in improving plant growth or plant development comprising a fermentation broth formulated for foliar application, wherein the fermentation broth comprises a mixture of cellular components from one or more strains of bacteria and one or more strains of yeast which have been grown in a broth to a range of about 10 6 to about 10 16 cfu/ml and then lysed in the broth;
wherein the bacteria are selected from the group consisting of Lactobaccillus, Streptococcus , and Propionibacter strains; and
wherein the yeast are selected from the group consisting of Saccharomyces, Candida, Pichia, Hanseniaspora, Metschnikowia, Issatchenkia, Kluyveromyces , and Kloeckera strains.
2. The plant biostimulant composition of claim 1 , wherein the bacteria are one or more of Lactobacillus plantarum, Streptococcus thermophiles or Propionibacter freudenreichii.
3. The plant biostimulant composition of claim 1 , wherein the yeast are Saccharomyces cerevisiae.
4. The plant biostimulant composition of claim 1 , wherein the one or more strains of bacteria or one or more strains of yeast are grown to a range of about 10 7 cfu/ml to about 10 9 cfu/ml.
5. The plant biostimulant composition of claim 1 , wherein the bacteria and the yeast are lysed by application of an increase in pressure followed by a rapid decrease in pressure.
6. The plant biostimulant composition of claim 1 , wherein the bacteria and the yeast are lysed by a fixed geometry fluid processor.
7. The plant biostimulant composition of claim 1 , wherein the plant biostimulant composition further comprises any one of a fertiliser, herbicide, insecticide, fungicide or mineral solution.
8. The plant biostimulant composition of claim 1 , wherein the plant biostimulant composition further comprises urea.
9. The plant biostimulant of claim 8 , wherein the urea is included at a range of about 0.15 kg/L to about 0.25 kg/L.
10. The plant biostimulant composition of claim 8 , wherein the urea is included at a range of about 0.18 kg/L to about 0.22 kg/L.
11. The plant biostimulant composition of claim 8 , wherein the urea is included at a range of about 0.35 kg/L to about 0.45 kg/L.
12. The plant biostimulant composition of claim 8 , wherein the urea is included at a range of about 0.38 kg/L to about 0.42 kg/L.
13. The plant biostimulant composition of claim 1 , wherein the plant biostimulant composition is a foliar spray.
14. The plant biostimulant composition of claim 13 , wherein the foliar spray is administered to the foliar growth of a plant.
15. A method effective in improving plant growth or plant development comprising a step of:
applying to a plant a plant biostimulant composition comprising:
a fermentation broth formulated for foliar application, wherein the fermentation broth comprises a mixture of cellular components from one or more strains of bacteria and one or more strains of yeast which have been grown in a broth to a range of about 10 6 to about 10 10 cfu/ml and then lysed in the broth;
wherein the bacteria are selected from the group consisting of Lactobaccillus, Streptococcus , and Propionibacter strains; and
wherein the yeast are selected from the group consisting of Saccharomyces, Candida, Pichia, Hanseniaspora, Metschnikowia, Issatchenkia, Kluyveromyces , and Kloeckera strains.
16. The method of claim 15 , wherein the yeast are selected from Saccharomyces strains.
17. The method of claim 15 , wherein the composition further comprises any one of a fertiliser, herbicide, insecticide, fungicide or mineral solution.
18. The method of claim 15 , wherein the plant biostimulant composition further comprises urea.
19. The method of claim 18 , wherein the urea is included at a range of about 0.15 kg/L to about 0.25 kg/L.
20. The method of claim 18 , wherein the urea is included at a range of about 0.35 kg/L to about 0.45 kg/L.
