ASSESSMENT OF COMPOST QUALITY OF SERICULTURE WASTE ON THE GROWTH OF Anogeissus leiocarpus USING TWO COMPOSTING METHODS
Keywords:Anoigesus leiocarpus, Compost, Growth, proximate, Sericulture
This study investigated the compost quality of sericulture waste on the growth of Anogeissus leiocarpus using two composting methods. The two-method adopted were M1 (pile method) and M2 (bin method). Sericulture waste which includes mulberry leaves and silkworm excreta were air dried for 24hours, measured (1 kg) and set in layers for both methods adopted. Samples of compost from each method were taken before planting to the laboratory for proximate analysis. Descriptive statistics and analysis of variance (ANOVA) were used to analyze the data obtained. Anogeissus leiocarpus seeds were soaked for 10 minutes at 35oC and at 9.5oC for 24 hours to enhance the breaking of its dormancy. Anogeissus leiocarpus seeds was planted using sericulture compost from both adopted methods. Result shows that M1 had the highest mineral composition. M1 recorded the highest (N %) with the value of 0.93%; (P %) with 0.089%; (K %) with 0.58%; (Ca %) with the value of 1.78% and (Mg %) with the value of 0.72% while M2 had a lower mineral composition. The result obtained for the early growth parameters shows that M1 had a higher plant height and stem girth which was significantly different from M2, the mixture of the two compost had the highest leaf count which was also significant while the control recorded the lowest value for all the parameters assessed. This result suggests that pile composting method is the best method for composting sericulture waste and can be used as a good and preferable alternative for inorganic manure in raising seedlings and trees species. Adopting the use of sericulture waste as compost will help in reducing the waste management problem, enhance economic use of farm waste and also help to ease the low germination rate and germination percentage of Anogeissus leiocarpus.
