Invention not patent able

A method of agriculture or horticulture is not an invention. Please refer Section 3(h).

Your method of treatment of plants to increase production or yield comes within the meaning of "method of agriculture," unless you're referrring to a chemical compound or mixture, such as organic fertizlier which can be patented.

Please PM me if you require more details.
