Effects of poultry manure on the growth of mansonia altissima seedlings

Abstract

The effects of poultry manure on the growth of Mansonia altissima seedlings was evaluated. The poultry manure and top soil were measured at different levels by the use of container at ratio 2:2 (TA) and 1:2 (TB) ratios of poultry manure to topsoil. The control contained only the top soil (TC) and each treatment was replicated 15 times. The experiment was set up in a completely randomized design and analysis of variance was used to determine the variation among the treatments. The morphological parameters assessed include: Shoot height, number of leaves and stem diameter. The mean value for stem diameter ranged from 0.210cm, 0.184cm and 0.173cm for treatment A, B and C (control) respectively, and the value for shoot height ranged from 8 for (TA) and (TB) with 8 leaves and (TC) with 6 leaves. Effect of organic manure did not reflect on the growth development of collar diameter of Mansonia altissima. Analysis of variance revealed that there was significant difference among the treatments for shoot height and number of leaves, but there was no significant difference among the treatments for collar diameter. It is concluded that Mansonia altissima generally responded positively to the application of poultry manure.
