AbstractThe importance of proper fertilizer placement has been demonstrated in recent greenhouse studies. Small, seemingly unimportant changes in fertilizer placement often in reality are very important. Specially constructed boxes with glass fronts were used to study root development as affected by fertilizer placement. Yields were significantly different one from another with the poorer ones resulting where fertilizers were placed too close to the seed piece. Yields ranging from 298 cwt, where the fertilizer was placed two inches to each side and level with the seed piece; up to 367 cwt where the fertilizer was placed four inches to each side and two inches below the seed piece. Root burning and speed of root regeneration represent the most important consideration to be reckoned within the proper placement of fertilizer.
