The effect of range of concentrations of Ergostim on growth recovery from pruning and yield of tea of different ages were studied. Foliar sprays of the concentration range 0.025-1.6 ml/l on young plants showed that best overall growth was obtained at the range 0.05-0.2 ml/l when the recommended fertilizer level was applied. A better response was obtained when the plants were given double the recommended level of fertilizer. Ergostim sprayed onto the pruned frames of mature bushes resulted in better recovery in terms of numbers of emerging buds and increased yields at 17 and 25 weeks after first spray application. Irrespective of harvesting bud +2 leaves or bud +3 leaves, improved crop was obtained after Ergostim spraying
