ABSTRACT

A trial was conducted at the Screen House of the Department of Crop Science, Faculty of Agriculture, University of Benin, Benin City, Nigeria to evaluate the effects of sowing depth, soaking and potting mixtures on the growth of Cashew seedlings. The trial involved three potting media (TS+PM 1:1 (3 kg of top soil and 3 kg of poultry manure), TS+PM 2:1 (4 kg of top soil and 2 kg of poultry manure) and TS+PM 1:2 (2 kg of top soil and 4 kg of poultry manure)). Three sowing depths (2, 4 and 6 cm) and three soaking time (0, 12 and 24 hours) laid out in a 3 × 3 × 3 factorial arrangements fitted into a completely randomized design (CRD) and replicated three times. Data were collected on plant height, stem girth, number of leaves, leaf area, dry matter and crop growth rate. Results showed that various top soil - poultry manure mixtures were variation in physical and chemical properties. Plant height, stem girth, number of leaves and leaf area vary among the potting medium. Increasing sowing depth decreased the growth of seedling while increasing soaking time increased the growth of cashew seedling. The highest dry matter was observed in TS+PM 2:1 potting medium, sowed at 2 cm depth and soaked for 24 hours.
