    Effect of sewage water with different potting media on growth and flowering of Marigold (Tagetes erecta L.) and Celosia (Celosia cristata L.)
    (Punjab Agricultural University, Ludhiana, 2017) Mann, Gagandeep Singh; Dubey, R.K.
    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.
