Abstract
Two experiments were performed to determine the effects of sawdust waste as a constituent of growth media for crops. Mean yields data for 3 species showed that mixtures of sawdust at 30% of soil volume with NPK fertilizers added to soil produced the highest yield. The second experiment studied the interactions of soil support materials and organic amendments. It was concluded that sawdust is a good growth medium when incorporated with suitable amounts of clay, ammonium nitrate and organic amendments.
