The performance of CO 3, CO 5 and Super Napier varieties planted in trench method under summer stress with irrigation support was evaluated. The experiment was conducted using different types of farmyard manure viz., cow dung, goat manure and poultry manure. Total yield, stem weight and projected yield did not differ significantly among the varieties. Survivability of CO 5 appeared low in the experiment (p<0.01). In general, the evaluated parameters were statistically significant (p<0.01) except tiller number, number of internodes, leaf weight and total weight. Stem weight was observed to be higher in CO 5 and Super Napier than CO 3 (p<0.01). Among all the parameters studied, the type of manure apparently influenced only leaf width (p<0.05). The yield (t/ ha) observed after the first cut of CO 3, CO 5 and Super Napier were 123.41±41.22, 153.27±45.33 and 145.82±28.67 tons respectively on fresh cut basis.
