ABSTRACT

The present investigation entitled, “Effect of NPK and organic manures on Plant growth, Flower yield and Flower quality of Dahlia (Dahlia variabilis) Hybrid “Eternity sports” was under taken in the Department of Horticulture, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Allahabad during rabi season (2015-2016). The experiment was layout in RBD having 13 treatments and 3replication. The treatments consisted of different combinations of NPK and organic manures i.e. inorganic fertilizers and FYM, Vermicompost and poultry Manure. The treatment T6 (50 % NPK + 50 % VM per ha-1) was found to be statistically significant compared to other treatment combination, which recorded highest Days required to first flower bud initiation (50.53),Days required duration of  flowering(64.93), flower stalk  length (25 cm), flower  diameter (25.13cm),Longevity of flower on plants (15.33 days) , Vase life in normal tap water (7.67 days), numbers of flowers per plant (10.13), yield of flowers per plant (908.34 g), Number of flowers per plot(60.8), Yield of flowers per plot (5.45 kg). Number of flowers per hectare (4.05 Lakhs), numbers of Tubers per plant (11), yield of Tubers per plant (637.99 g), Number of Tubers per plot (66),Yield of Tubers per plot (5.45 kg). Yield of Tubers per hectare (25.35 q) followed by T5(50 % NPK +50 % FYM per Ha-1)except weight of Single Flower (92g) and weight of single tuber (53.6g) where the treatment T₇ (50% NPK + 50% PM per Ha-1) found significant followed by the treatment T6 (50 % NPK + 50 % VM per Ha-1) and lowest yield was obtained from T0 (control).
