Pest Management
To determine the influenced of PLRV, PYV and Yellows on the yield of potato.
Potato variety Diamant was used for PLRV and PYV experiment, whereas, the variety Challisha was used for Yellows disease experiment, apparently healthy and infected plants were tagged separately based on symptomatology. In case of PLRV and PYV, 30 plants were selected and tagged for each replication (three replication was done) and in case of variety Challisha, 50 plants were selected and tagged per replication. All the tagged healthy and infected plants were harvested and yield per plant in gram was calculated. Yield reduction due to diseases was analyzed separately compared with the healthy one.
