A field experiment was carried out to investigate the effects of application of cow dung, goat and poultry manure on the growth parameters of Napier hybrid in Chenkalady, Batticaloa. Treatments were laid out in a Randomized Complete Block Design (RCBD) with three replications. The variables measured were plant height, leaf length, leaf width and tillers number obtained. Data collected were subjected to Analysis of Variance (ANOVA). The means were separated using LSD at 5% level of significance. Results obtained indicated that growth performance of CO3 was lowest in control treatments while positive influence showed in the application of organic manure applied in this study especially poultry manure. The results also revealed that plots treated with poultry manure gave the highest number of tillers with longest and width leaves per grass. Comparatively, second highest growth performance was obtained with the application of goat manure and cow dung. While the least performance of CO3 were recorded in the control treatments. Based on the findings of the experiments it could be deduced that organic manure seems to promote higher growth and yield of CO3. Application of organic manure on Napier hybrid give maximum growth performances, and yield with sustainable and free polluted farming.
