A Comparative Study on the Effect of Foliar Application of NPK and ‎Different Mediums on Melia azedarach L. Growth

Abstract

An experiment was conducted to study the effects of NPK foliar application and three different Mediums including (Sand, Compost and Peat moss) on the growth of pre-sowing Melia azedarach L. seeds. NPK application (20-20-20) at 500 ppm concentration significantly increased of shoot length 202.58 mm, shoot dry weight 1.93 g, root fresh weight 0.68 g and root dry weight 0.37 g. Seeds sowed in three different mediums; Sand, Compost and Peat moss the results showed that Peat moss had best performance in almost all the parameters shoot diameter 2.52 mm, shoot length 248.92 mm, shoot dry weight 2.23 g and root fresh weight 0.83 g. Interaction of medium Peat moss with NPK 500 ppm significantly increased all the studied parameters.
