Abstract

Described are compositions and methods to increase bud break in order to increase aspects of one or both of plant vegetative and reproductive growth, by use of a natural metabolite. In particular, the present disclosure provides a natural metabolite either alone or as part of a fertilizer blend to increase crop production. Additionally the present disclosure provides a natural metabolite in combination with one or both of a plant growth regulator and a bio stimulant to increase crop production.

First claim

I claim:

1. A method of increasing crop production, comprising administering to a crop plant a composition comprising a fertilizer and an effective amount of a nucleoside comprising adenosine, wherein said composition does not contain other nucleosides, and wherein said nucleoside comprises at least 75% 9 beta-D-adenosine (9BDA).

2. The method of claim 1 , wherein the composition further comprises one or both of a plant growth regulator, and a biostimulant.

3. The method of claim 1 , wherein the fertilizer is selected from the group consisting of nitrogen, potassium, magnesium, phosphorus, calcium, sulfur, iron, boron, chlorine, manganese, zinc, copper, molybdenum, nickel, cobalt, silicon, selenium, and combinations thereof.

4. The method of claim 1 , wherein the crop plant is a perennial fruit plant.

5. The method of claim 4 , wherein the perennial fruit plant is selected from the group consisting of apple, apricot, avocado, citrus, peach, pear, pecan, pistachio, and plum.

6. The method of claim 4 , wherein the composition is administered at one or more of the following times: (i) at 10% anthesis, (ii) at full bloom, (iii) 30 days after 75% petal fall, (iv) at maximum peel thickness of the fruit, and (v) greater than 60 days before fruit harvest.

7. The method of claim 1 , wherein the crop plant is an annual crop plant.

8. The method of claim 7 , wherein the annual crop plant is selected from the group consisting of celery, spinach, and tomato.

9. The method of claim 7 , wherein the composition is administered, one, two, three, four, five, six or seven times per week.

10. The method of claim 1 , wherein the composition is administered by a technique selected from the group consisting of foliar spray, irrigation, and trunk injection.

11. The method of claim 1 , wherein the increased crop production comprises an increase in reproductive growth.

12. The method of claim 11 , wherein the increase in reproductive growth comprises an increase of one or more of the group consisting of number of fruiting shoots, number of fruit, fruit size, and total yield of fruit.

13. The method of claim 11 , wherein the increase in reproductive growth comprises an increase in yield of commercially valuable large fruit on a per plant or per plot basis.

14. The method of claim 1 , wherein the increased crop production comprises an increase in vegetative growth, wherein the increase in vegetative growth comprises an increase in one or both of number of leaves and number of vegetative shoots.

15. The method of claim 1 , wherein the crop plant is a fruit tree.

16. The method of claim 1 , wherein the crop plant is an orange tree.

17. The method of claim 1 , wherein the crop plant is an avocado tree.
