Impact of the Mineral Fertilization on the Germination and Growth of <i>Acacia auriculiformis</i> A. Cunn. ex Benth by the Soilless Technique in Nursery

The growing demand in wood energy requires mechanisms of production the seedlings with a view to proceed reforestation answer needs populations. study evaluates germination and growth Acacia auriculiformis two types substrates by soilless technique. seeds A. species have been collected Democratic Republic Congo sent at Bateke Brazzaville Forest Plantations Society (SPF2B-nurseries God willing). They kepted cold for 20 days refrigerator an temperature about 5°C. A complete device (substrate fertilized NPK 11-7-6, unfertilized substrate, i.e. 1152 per substrate) has set up Batéké Society. For fertilization, we taken 1000 grams (i.e. 1 liter cup soaked 10 watering can). Seeds sowned individually each alveolus after treatment. results reveal rates 20.8% 23.7%, respectively substrate substrate. However, mortality 76.3% 79.2% recorded Kolmogorov-Smirlov test demonstrated that there are significant differences (p-value = 0.86 p-value 0.200) on seed germination. As far as goes, 11-7-6 fertilization had effect (p-value= 0.307) growth. mean number phyllode Shairo-Wilk values 0.243 0.436 substrate). In so industrial mineral fertilizer contribution nursery, suggests large-scale from nurseries ensure sustainability plant considering importance it plays nitrogen-fixing bacteria soil.
