Earthworm Processed Weeds on Plant Growth Attributes

摘要

Weed biomass is one of the potential sources of organic matter and nutrients if perfectly utilized. In recent years increased emphasis has been produced globally for integrated use of biofertilizers and organic manures. Weeds are the constraints in successful crop production. Similarly, most of the dicot weeds are also used as medicine, vegetables, feed, and fuel and for compost making. In the (Ipomea carne, Jatropha curcas, Datura inoxia and Calotopis gigantea) and evaluated for their nutrient status of vermicomposts. The result revealed that the nutrient status, maximum plant growth and yield was higher in the nitrogen, potassium, phosphorus (NPK) value for the following vermicomposts Ipomea carnea (2.49,0.8,0.15) Jatropha curcas (1.23,0.1,0.10) Datura inoxia (1.4,0.7,0.3) and Calotropis gigantea (1.7,0.1,0.63) compared with control. Hence, it was terminate that the aforesaid vermicomposts are higher nutrients and higher yielding in Ipomea carnea and Jatropha curcas vermicomposts. Thus, the weeds are not waste, to be approach the formers.
