The reuse of peanut organic wastes as a growth medium for marigold, viola tricolor and dracaena marginata plants
AbstractThis research conducted to evaluate the possibility using peanut shells compost as a suitable medium in cultivating ornamental plants. Peat + perlite with a ratio of 2:1 without peanut shells compost used as control treatment. Peat replaced by 25, 50, 75 and 100 % V/V of peanut shells compost in control. Plant growth characters include height, Stem and leaf fresh weights and stem and leaf dry weights measured in marigold, Viola tricolor and Dracaena marginata plants. Results showed that peanut shells compost had more effects on growth properties like height, stem and leaf dry weigh in comparison to control. The lowest growth related to 100% treatment of peanut shells and control. The most growth of Viola tricolor, Dracaena marginata and Marigold plants resulted in 25, 50 and 75 % peanut shells compost, respectively. Results show that increasing compost peanut shells as well as reducing the use of peat, can be effective on the ornamental plants growth. The results revealed that using composted peanut significantly increased plant height and stem diameter.
