Abstract

                                "Ergostim", a proprietary biostimulant was used in the present study. Ergostim at 0.05%. 0.075% and 0.1% aqueous solution was sprayed once and twice during each leaf crop period under a 5 leaf crop schedule in irrigated mulberry garden. Results indicated that two aqueous sprays of Ergostim 0.05%, 0.075% and 0.1% significantly increased the linear growth and number of leaves per plant as well as leaf yield over single spray and also control. It was found that two aqueous sprays of 0.05% Ergostim gave highest net return of Rs.3,223/ per ha per year than that of 0.075% and 0.1% of Ergostim sprays. The Cost-benefit ratio indicates a single spray of 0.05% Ergostim is more cost effective.
