Different combinations of river sand, cow dung and coir dust were compared with the conventional polybag mixtures to study whether seed germination would be affected by the substitution of top soil with river sand. The seed nut germination at 20 weeks was significantly reduced in the sand substituted media, but the difference disappered by 24 weeks from laying. The lower rate of germination was also associated with a reduction of seedling vigour at 30 weeks, probably due to poor seedling nutrition. River sand could be used as an alternative to top soil, provided the nutritive status of the sand is improved and refinements are made to decrease its rate of drying.
