The present study was undertaken to elucidate the effect of organic manures (Vermicompost, farm yard manure, Silkworm rearing waste, Neem cake) alone and in combination with biofertilizer (Azospirillum) on mulberry variety (China white) and its impact was studied on larval duration of silkworm hybrid (FC1× FC2). Less significant results were recorded when larvae reared on leaves raised through the application of Vermicompost @ 4kg/plant + Azospirillum (4.0g/plant). Further FYM@ 4kg/plant + Azospirillum (4.0g/plant) found next best with respect to larval duration. Consequently the present experiment revealed that Vermicompost @ 4kg/plant + Azospirillum (4.0g/plant) is responsible to produce good quality mulberry leaves and shorter larval duration followed by FYM@ 4kg/plant + Azospirillum (4.0g/plant) found next best with respect to larval duration. Thus, application of Vermicompost + Azospirillum (T6) after pruning could form a suitable organic manure and biofertilizer combination from overall sericultural point of view.
