Carbonized rice husk as an alternative substrate for Ocimum basilicum L. seedling production

The substrate used in seedling production plays a major role the initial plant development. In this sense, objective was to evaluate emergence capacity and establishment of basil seedlings different proportions alternative substrates based on charred rice husk commercial S10®. experiment carried out expanded polyethylene trays, using seeds (Horticeres seeds®), which lasted 28 days. experimental design completely randomized, with five treatments (T1: 100 % (BCS); T2: 80 BCS + 20 Charred (CRH); T3: 60 40 CRH; T4: T5: CRH) three repetitions. Were evaluated leaf number, shoot length, root dry mass, area, germination, germination speed index, physical analysis (density (dry wet)), total porosity aeration space, chemical (hydrogen potential (PH), electrical conductivity (EC)). It observed results that type interferes development quality seedling. lenght parameter, treatment CRH (T4) had significant difference compared other treatments. Among substrates, best performance (T2), provided better relation
