impatiens, production, substrates.
Impatiens is used for home decoration, balconies, terraces and in parks and gardens. Impatiens are popular because they’re easy-to-grow and flower in shade all season. The aim of the present study was to investigate the effects of some alternative substrates (compost + fallow) on the growth of a bedding annual plant. Results showed that it is possible to obtain high quality Impatiens ssp. plants grown in local material. The effect of changes in height, number of leaves and flowers, and leaf sizes are discussed. It is advisable to cultivate the three Impatiens varieties on a substrate consisting of unimproved peat or NPK-improved peat as they have high productivity and great commercial appearance. Comparative study of Impatiens varieties on different substrates is necessary to recommend to the growers the most suitable substrates depending on the variety, leading to obtain great productions.
