Abstract


This study shows the comparative effects of Bactériosol®, compost from green waste, developed by Mezy (1978) and other organic and chemical fertilizers to increase growth and development of cultivar of date palm ‘Bouffgouss‘ (Phoenix dactylifera L.) cultivated in greenhouses at the nursery of Marrakesh. We examined the effectiveness of Bactériosol ® compared with natural manure and chemical NPK fertilizer applied at different concentration. Four months after application of various amendments on the culture substrate of date palm aged 16 months, the effect on the biomass production occurred for treated plants by Bacteriosol® compared to other treatments with chemical fertilizers or natural fertilizers. The ionic contents of N, P, K and Na are significantly higher in plants treated by Bactériosol ® than other plants. The beneficial effect of Bactériosol ® on biomass and plant state is remarkable on young date palm.
