Abstract :
The effect of potash biofertilizer and chemical fertilizer was studied
on quantitative and qualitative traits of periwinkle in a factorial experiment
based on a Randomized Complete Design with three replications, 48 experimental
units, and two factors: (1) different methods of potash bio-fertilizer
application at four levels of control (B0), seed inoculation (B1), root
inoculation (B2) and seed inoculation × root inoculation (B3), and (2)
different rates of potassium on fertigation at four levels of 0 (K0), 100 (K1),
200 (K2) and 300 mg L-1 (K3). It was found that the longest shelf life of
35.58 days was related to the treatment of root inoculation × 100 mg L-1 K.
The highest number of auxiliary branches (3.66), number of leaves (42.88),
plant fresh weight (17.69 g), number of flowers (4.46), and chlorophyll a
(10.61 mg g-1 F.W.) were obtained from the treatment of seed inoculation ×
300 mg L-1 K. The treatment of root inoculation × 200 mg L-1 K was the best
treatment for plant potassium content (28.9 mg kg-1). The highest petal anthocyanin
content amounted 178.04 mg 100 g-1 D.W. was observed in the
treatment of ‘seed inoculation × root inoculation’ × 0 mg l
-1 K. The best
treatment of enhancing of qualitative and quantiative traits of periwinkle
was seed inoculation × 300 mg L-1 K.
