Methods for enhancing the productivity of plants
First Claim
1. A method for enhancing a selected physiological response of plants other than beets and sugarbeets which comprises contacting the foliage of said plants during about the first half of the grand response period for said physiological response with a solution comprising dissolved biuret in an amount and under conditions sufficient to introduce into said plant a non-phytoltixic amount of biuret sufficient to enhance said selected response.

Abstract
The productivity of plants is enhanced by enhancing one or more physiological responses of photosynthesizing plants by contacting the foliage of such plants during the early stages, i.e. about the first half, of the grand response period for the selected physiological response with a solution containing biuret in an amount and under conditions sufficient to introduce into the plant a non-phytotoxic amount of biuret sufficient to enhance the selected physiological response.

- 1. A method for enhancing a selected physiological response of plants other than beets and sugarbeets which comprises contacting the foliage of said plants during about the first half of the grand response period for said physiological response with a solution comprising dissolved biuret in an amount and under conditions sufficient to introduce into said plant a non-phytoltixic amount of biuret sufficient to enhance said selected response.
- 36. A method for enhancing the flower set of flowering plants which comprises contacting the foliage of said plants during about the first half of the blossom-set period for said plants with a solution comprising dissolved biuret in an amount and under conditions sufficient to introduce into said plant a non-phytotoxic amount of biuret sufficient to enhance the blossom set of said plants.
- 38. A method for enhancing the fruit set of fruit-bearing plants which comprises contacting the foliage of said plants during about the first half of the fruit-set period for said plants with a solution comprising dissolved biuret in an amount and under conditions sufficient to introduce into said plants a non-phytotoxic amount of biuret sufficient to enhance the fruit-set of said plants, wherein said solution is applied to the foliage of said plants at a rate corresponding to at least about 1 ounce of biuret per acre, and the biuret/urea weight ratio in said solution is at least about 0.1.
- 39. A method for enhancing the grain production of grain-bearing plants which comprises contacting the foliage of said plants during the first half of the grain-head filling period for said plants with a solution comprising dissolved biuret in an amount and under conditions sufficient to introduce into said plants a non-phytotoxic amount of biuret sufficient to enhance the grain production of said plants, wherein said solution is applied to the foliage of said plants at a rate corresponding to at least about 1 ounce of biuret per acre, and the biuret/urea weight ratio in said solution is at least about 0.1.
- 40. A method for enhancing the production of harvestable root parts by root crops selected from the group consisting of potatoes, carrots, garlic, turnips, onions, peanuts, parsnips, radishes, shallots and yams which comprises contacting the foliage of said root crops during about the first half of the grand growth period for the development of the harvestable root parts of said root crops with a solution comprising dissolved biuret in an amount and under conditions sufficient to introduce into said root crops a non-phytotoxic amount of biuret sufficient to enhance the production of said harvestable root parts, wherein said solution is applied to the foliage of said root crops at a rate corresponding to at least about 1 ounce of biuret per acre, and the biuret/urea weight ratio in said solution is at least about 0.1.
- 41. A method for enhancing the cotton production of cotton plants which comprises contacting the foliage of said plants during about the first half of the blossom-set period for said plants with a solution comprising dissolved biuret in an amount and under conditions sufficient to introduce into said plants a non-phytotoxic amount of biuret, wherein said solution is applied to the foliage of said plants at a rate corresponding to at least about 1 ounce of biuret per acre, and the biuret/urea weight ratio in said solution is at least about 0.05.
- 42. A method for enhancing the cotton production of cotton plants which comprises contacting the foliage of said plants during about the first half of the boll-set period for said plants with a solution comprising dissolved biuret in an amount and under conditions sufficient to introduce into said plants a non-phytotoxic amount of biuret, wherein said solution is applied to the foliage of said plants at a rate corresponding to at least 1 ounce of biuret per acre, and the biuret/urea weight ratio in said solution is at least about 0.05.
-
43. A method for enhancing the cotton production of cotton plants which comprises contacting the foliage of said plants during about the first half of the grand growth period for cotton boll growth on said plants with a solution comprising dissolved biuret in an amount and under conditions sufficient to introduce into said plants a non-phytotoxic amount of biuret, wherein said solution is applied to the foliage of said plants at a rate corresponding to at least about 1 ounce of biuret per acre, and the biuret/urea weight ratio in said solution is at least about 0.05.
- 44. A method for enhancing the sugar production of sugar producing plants selected from the group consisting of sugarcane, and fruiting plants, which comprises contacting the foliage of said plants during about the first half of the sugar accumulation period in said plants with a solution comprising dissolved biuret in an amount and under conditions sufficient to introduce into said plants a non-phytotoxic amount of biuret, wherein said solution is applied to the foliage of said plants at a rate corresponding to at least about 1 ounce of biuret per acre, and the biuret/urea weight ratio in said solution is at least about 0.05.
- 53. A method for enhancing a physiological response selected from the group consisting of blossom set, fruit set, fruit growth, grain-head filling, root-crop developement, sugar accumulation, and combinations thereof, of plants selected from the group consisting of flowering plants, fruiting plants, fruiting vegetables, seed and pod vegetables, nut crops, grain-bearing plants, carrots, chicory, garlic, onions, parsnips, potatoes, radishes, rutabagas, salsify, shallots, turnips and yams, which comprises contacting the foliage of said plants during about the first half of the grand response period for said physiological response with a solution comprising dissolved biuret in an amount and under conditions sufficient to introduce into said plants a non-phytotoxic amount of biuret sufficient to enhance said physiological response, wherein the biuret/urea weight ratio in said solution is at least about 0.5.
