Abstract
The present invention describes a protein guarantor composition and its application, in particular to improving the protein content of cereals. The protein guarantor composition containing urea as nitrogen source and incorporating deacylated chitin proves noteworthy, by virtue of the increase in the protein content of the grain. This composition does not cause harmful scorching of the foliage and its apparent use coefficient for nitrogen is much better than that of the nitrogen fertilizers applied to the soil.
Claims8
A composition for increasing the protein content of grains, said composition consisting of a neutral aqueous mixture comprising urea in the proportion of 150 to 220 grams of nitrogen per liter and chitosan in the proportion of 0.2 to 10 grams per liter.
A process for improving the protein content of a cereal crop, which process comprises spraying onto the foliage a protein guarantor composition consisting of a neutral aqueous mixture comprising urea in the proportion of 150 to 220 grams of nitrogen per liter and chitosan in the proportion of 0.2 to 10 grams per liter, wherein said spraying is conducted at a period in the growth cycle of said cereal selected from the periods ranging from the end of swelling of the ear stage to the flowering stage.
