Title : Influence of wastes of taro leaf, sugar beet and saw dust on physiochemical parameters of produced vermicompost
Abstract:
Climatic changes and its negative impacts may is represented one of big global challenges and eliminate soil and water availability time by time. Thereby, adding organic fertilizers (i.e vermicompost) as soil amelioration may consider one of effective approaches in order to recover soil degradation and enhance water retention in soil. Through vermicomposting, agro-wastes are converted into vermicompost that rich in humus, growth promoters (i.e. amino acids, growth hormones) and nutrients.
Current work was carried out during 2019-2020 to investigate impact of different agro-wastes types i.e. Taro leaf (TF), Saw Dust (SD) and Sugar Beet (SB) on vermicompost quality. Obtained results indicated that these agro-wastes resulted in varying of physiochemical parameters and vermicompost content of amino acids and growth promoters. Whereas, adding SD to Cow dung during vermicomposting resulted in raising Organic matter and N content. Meanwhile, adding SD to FS resulted in increment in C:N ratio and P content in vermicompost. Besides, adding TL to cow dung during vermicomposting led to increment in amino acids. In addition, adding SB to cow dung during vermicomposting resulted in raising ABA and GA3 content. Moreover, these different agro-wastes resulted in varying microbial activity and the highest activities produced when TL adding to FS during vermicomposting. Finally, these different agro-wastes led to differing in antimicrobial activity in produced vermicompost. From these resulted, research team concluded that there is a great potential to produce vermicompost with specific quality that may play a crucial role in combat climatic changes particularly reinforce tolerant plant to drought stress .
