The experiment was designed considering recycling and reuse of the agricultural crop (<em>Zea mays</em>) residues and native wetland plants (<em>Canna indica, Cyperus alternifolius, Acorus calamus&nbsp;</em>and&nbsp;<em>Hydrocotyle vulgaris</em>) and pig manure found in Sichuan Basin, China. A total of fourteen treatments (V1-V14) were prepared and the experiment for V1 to V4 treatments was set-up in cemented plots and separate experiments were set-up for V5-V8 and V9-V14 in containers for three months (September to December 1517). The amount of total nitrogen (TN) improved in all the treatments (V1-V14) throughout experimental period of 90 days. In case of group 1, considering major parameters like TOC, C:N ratio and TN, combination of&nbsp;<em>Zea mays&nbsp;</em>and&nbsp;<em>Canna indica</em>&nbsp;(V3) can be regarded as most suitable combination for vermicomposting. In the second group, V6 treatment [(<em>Cyperus alternifolius&nbsp;</em>(60%): Pig manure (40%)) was found to be suitable based on TN recovery. The mixture of combined&nbsp;<em>Zea mays</em>&nbsp;(50%),&nbsp;<em>Cyperus alternifolius&nbsp;</em>(5%),&nbsp;<em>Acorus calamus</em> (5%) and pig manure (V13) increased 76% TN and can be regarded as best in group 3 based on percent change. Results indicated that ditch plants and crop residues can be used as substrates in vermicomposting for nutrient recovery.</p> Crop residues, Wetland plants, Vermicompost, Nitrogen, Sichuan Basin Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=AG-20-0180
