“…It is probable that any loose material affording suffi cient aeration and room for unrestricted development of the rootlets would give similar satisfactory results. Northwood (1964) andPeixoto (1960) reported similar results in Brazil and India, respectively, and the former recommended the use of a mixture of sand and peat or well-composted organic materials. The materials used in the mixtures in the present study are, however, economical, cheap and available in abundance for resourcepoor farmers, unlike the commercial Sphagnum moss often recommended.…”

An evaluation of three different rooting media (topsoil, sawdust and river sand) mixed in different proportions for the rooting of cashew layers was carried out at the Cocoa Research Institute of Nigeria at Ibadan, southwestern Nigeria. Data were collected on percentage take, number of days to rooting, number of roots, root length and percentage sprouting, and were statistically analysed. Signifi cant differences were recorded for the effects of medium, mixture proportion, genotype and medium × mixture proportion interaction, showing the strong infl uence of the rooting medium (and thus its composition -texture, nutrient status and water-holding capacity) and the variation in genotypic response to rooting in cashew layers. Topsoil ranked best among the three media tested, and its combination with either sawdust or river sand in the ratio 1 : 1 (v/v) gave the best rooting and sprouting, thus suggesting its use as an effective rooting medium for cashew layering. volume) was placed over the cut portion and wrapped in polythene sheet (about 23 cm long × 45 cm wide) with both ends tied. The rooting media were kept wet with periodical watering to avoid drying of the layers and monitored constantly for rooting response. Layers with green leaves and having at least one root ≥1 mm long were classifi ed as taken and rooted. Data were collected on percentage take (PTK), number of days to rooting (NDR), number of primary roots (NRT), length of roots to calculate mean length of root per marcot (LRM) and percentage sprouting (PSR) after planting into polypots. The data were statistically analysed by analysis of variance (ANOVA) of split-split plot design using Costat software. Mean values were calculated for all the parameters and tested for signifi cant differences with Duncan's multiple range test. OM Aliyu
