Assiut Journal of Agricultural Sciences 31(2): 1-19
An investigation at Assiut University during 1998 and 1999 studied the combined effect of planting media (clay, sand and clay+sand (1:1 v/v)) and NPK fertilization on growth, flowering and chemical composition of Aster novi-belgii. Fertilizer treatments included 3 mixtures of N:P:K; (5:0:0), (5:5:0) and (5:5:5) besides the control (unfertilized plants). Each mixture was added at 25 grams per plant, divided into 5 equal portions at 3 week intervals.
