Certain factors affecting the production of container-grown ornamental peppers (Capsicum annuum L.)

Abstract

The objectives of this study were to examine three aspects of the production of Capsicum spp. grown as ornamental peppers: 1. Nutritional trials are set up to examine the influence of N, P, K, Ca and Mg on growth and quality of container-grown ornamental peppers and to determine suitable nutrient levels for a potting mix to be used for the production of these peppers. 2. Shade experiments are conducted to study the influence of light levels on the production of container-grown ornamental peppers and to recommend, if appropriate, a specific production light level for optimum growth and plant quality. 3. Experiments with growth regulators are intended to investigate the value of foliar sprays of B9, CCC and Ethrel as a substitute for hand-pinching to produce compact and high quality ornamental peppers. Recommendations could then be made on suitable spray concentrations for each of these growth regulators.
