Seedling emergence and growth of some accessions of African walnut (Plukenetia conophora ) in different growing media
Abstract
In this study, nursery experiments were conducted to evaluate the effects of planting media on seedling emergence and seedling growth among some accessions of Plukenetia conophora (Mull. Arg.) with the aim of determining the most appropriate method of obtaining optimum and uniform germination of seeds of this species. Seeds of eight accessions of Plukenetia conophora were collected from five States in Nigeria and were in three different growing media. Results show that planting media significantly affected seedling emergence and seedling growth of Plukenetia conophora. Accession AC4 recorded the highest emergence percentage and quicker seedling growth and was significantly (P<0.001) different when compared with the other accessions, while AC8 recorded the least emergence percentage 90.0%). Sawdust recorded the highest effect on emergence and seedling growth and was significantly (P<0.001) different from other planting media, while topsoil recorded the least effect on emergence and seedling growth of P.conophora. Sawdust produced superior plant growth in terms of plant height, collar girth and leaf number.
