Abstract
The present study was conducted to evaluate the Interactive effect of treated sewage water
and organic potting media on growth and flowering of Tagetes erecta Linn. and Celosia
cristata Linn. Four main organic potting media Soil + Farm Yard Manure (FYM), Cocopeat +
FYM, Burnt Rice husk (BRH) + FYM and Cocopeat + BRH + FYM were used and plants
were irrigated with Tap water (100%), Sewage water (100%), Tap water + Sewage water
(25%:75%), Tap water + Sewage water (50%:50%) and Tap water + Sewage water
(75%:25%). Maximum plant height (47.88 cm), plant spread (23.80 cm), number of branches
/ plant (8.80), early bud appearance (49.26 days), early flowering (66.28 days), more number
of flowers/plant (34.37), more duration of flowering (57.01 days), larger flower size (5.27
cm) and individual flower life (11.03 days) of marigold were observed in Cocopeat + BRH +
FYM. Sewage water (100%) showed maximum plant height (45.08 cm), plant spread (23.44
cm), number of branches/plant (9.03), early bud appearance (48.67 days), early flowering
(67.96 days), more number of flowers/plant (32.55), more flowering duration (54.38 days),
larger flower size (5.33 cm) and individual flower life (10.51 days) in marigold.In celosia
maximum plant height (69.63 cm), plant spread (30.22 cm), number of branches/plant
(11.80), early bud appearance (51.06 days), early flowering (66.90 days), more number of
flowers/plant (34.03), more duration of flowering (73.13 days), larger flower size (21.32 cm)
and individual flower life (17.94 days) were observed in Cocopeat + BRH + FYM. Sewage
water (100%) showed maximum plant height (61.94 cm), plant spread (28.04 cm), number of
branches/plant (10.33), early bud appearance (53.03 days), early flowering (68.84 days), more
number of flowers/plant (32.29), more flowering duration (69.31 days), larger flower size
(20.05 cm) and individual flower life (17.43 days) in celosia. Cocopeat + BRH + FYM shows
the maximum pH (7.73), percent available N (0.89%), percent available P (0.55%), percent
available K (1.03%), total porosity (83.1 %), BRH + FYM shows maximum EC (5.40 dS/m).
Sewage water (100%) shows maximum pH (7.73), EC (2.10 dS/m), N (0.91mg L-1), P (1.67
mg L-1) and K (24.13 mg L-1). Tap water shows minimum N, P and K.
