Abstract
The
present study was conducted to study the individual and combined effect of
bio-fertilizer (Barvar-2) and chemical phosphate fertilizer on the floral
quality of marigold (Tagetes erecta L.). A factorial experiment was
carried out which consisted of? two factors: i) inoculation of seed, root and
seed + root with bio-fertilizer (Barvar-2) and control;
application of chemical phosphorus at 100 mg l-1, 200 mg l-1, 300
mg l-1 and 400 mg l-1 levels. In this study, flowering time,
display life, fresh and dry weight of flower, available soil phosphorus,
shoot phosphorus and carotenoid content were evaluated. Results showed that
the combined effect of bio- and chemical fertilizer was insignificant (p<1
and 5%) for most of the characteristics studied except for shoot phosphorus
and carotenoid content in petals. The lowest time to flowering (64.67 days)
was obtained in seeds and transplant roots inoculation to bio-fertilizer ?
400 mg l-1 P. Maximum display life (25.35), fresh weight (16.20
g), carotenoid content (3.903 mg g-1 d. wt.) and concentration of
P in shoots (0.352%) were observed in transplant roots inoculation to
bio-fertilizer ? 400 mg l-1 P.
