ABSTRACT
This reseach was caried out to
determine the effects of different salinity levels and leaching fractions on
the yield and plant quality of gerbera (Gerbera jamesonii sklylina) grown in
perlite. Plants were fed with nutrient solution composed of macro and micro
elments added to irrigation water. The salinity level of this nutrient solution
was considered as the control (S1). The electrical conductivity of the nutrient
solution in the other three treatments was increased by 1 (S2), 2 (S3) and 3
(S4) dS m-1 above the control by NaCI addition. Irrigation water
volume was determined by leaching fractions which was attempted to be kept
around 25% (LR1) and 50% (LR2). The results showed that there was no
significant difference between leaching fractions in respect to yield, whereas
yield decreased dramatically with the increasing salinity. The highest yield
was obtained from the treatment of LR2 as 98.30 flower m-2. Among
the salinity levels, the highest yield was obtained from the treatment of S1
(117.63 flower m-2).
