In Senegal, the rainfall deficit and pressure exerted on natural resources have affected production potential of forest agroforestry formations.Their optimal restoration requires superior quality plants thanks to seeds but also an technological package germination initial growth young plants.The objective is study, in a completely random device, influence substrates pretreatments nuts A. occidental nursery ISFAR.The results obtained show that axes weight evolve same direction.The length width vary between 1 4.4 cm 0.6 2.3 while mass fluctuates 4 14 g.The average period 15 ± 8 days.Vermiculite (VM), soil under 15-year-old cashew 29-year-old (A29) more than 50% 15th 20th JAS reach peak 68%, 66% 62% at 30 days.On other hand, millet bullet (BM) gave 55.3% beyond JAS.For rice husk (BR) compost (TR), no clear intersection non-germination curves noted with rates less throughout test, i.e. 48.7% 44% .For pretreatments, only scarification (S) untreated control (NT) had sprouted final rate 77.8% 72.8%.As for growth, recorded best height, 18.1cm compared (TR) (11.4cm).However, from scarified greatest height 17cm (16.9cm).For diameter, largest presented by (A15) 0.6cm pre-treatments, (H) revealed highest value, 0.63cm.In view results, Influence of…
