Abstract

Common scab of potato is most important disease of potato in all over the world. It reduces market and cosmetic values of potato due to presence of obnoxious scab lesions on skin of tubers. In present study we evaluated effect of fertilizer NPK with different concentrations on development of common scab of potato. Three concentrations of N (N1= 100 kg, N2= 125 kg, N3 75 kg), P (P1 = 75 kg, P2= 100kg, P3= 50kg) and K (K1= 50kg, K2= 75kg, K3= 25kg) were used in experiment. These concentrations of fertilizers significantly reduced disease incidence. Maximum disease incidence (61%) was recorded in N1 as it is in N2 disease incidence was (54%) and in N3 (42.2%). In case of P treatment P2 showed minimum disease incidence (40.6%) as compared to P1 (52%) and P3 (45.6%). Maximum reduction of disease was observed in K1 (44%) and minimum disease severity was observed in K3 (40%). The experiment was laid out in (RCBD) randomized complete block design in research area of department of plant pathology, University of Agriculture Faisalabad.
