| Abstract: |
Farm Yard Manure (FYM) is an integral component of agricultural input in small holder Nepalese farming communities where mixed cropping system (agriculture and livestock integration) is practiced. Despite of quality of FYM produced in farm level appropriation of right dose in farmers' field is not achieved yet. So, to quantify appropriate level of FYM in farmer field this experiment was conducted at research farm of IAAS from October 2012 to May 2013 catching major two crop growing seasons i.e. winter and spring season in which broccoli and Mung bean were cropped, respectively. Six treatments (0, 10, 20, 30, 40, 50 t ha-1 FYM) were replicated four times. In each plot 100 earthworms were released in one square meter earthworm inoculation unit. Soil organic carbon (SOC) and earthworm growth rate was significantly influenced by FYM levels of 30 t ha-1 in both seasons. EC1:5, nitrate nitrogen, ammonium nitrogen also achieved highest at this dose in winter and spring seasons. Hence, once application of 30 t ha-1 FYM is sufficient to maintain earthworm population and soil properties in the field growing cole crops followed by legumes in rotation. |
