Abstract:
The present investigation on “Studies on effect of organic manures, biofertilizers on growth, yield and quality of Turmeric (Curcuma longa L.) Varieties” was conducted at College of Horticulture, Rajendranagar, SKLTSHU, Mulugu during 2018-19. The experiment was laid out in Factorial Randomized block design (FRBD) with 2 replications and 18 treatments. The results revealed that among all the organic manures, biofertilizers, varieties and their combinations, treatment M₁–FYM 45 t/ha + AMC (Arka microbial consortium) 1 lit per quintal manure recorded maximum antioxidant activity (12.01 µg mL^-1) followed by M₃–Vermicompost 14 t ha^-1 + AMC (Arka microbial consortium) 1 l q^-1 compost (12.53 µg mL^-1) and M₄ – Neem cake 4.5 t ha^-1 + AMC (Arka microbial consortium) 1 l q^-1 neem cake (12.90 µg mL^-1). Among the varieties, Salem recorded significantly the highest values for antioxidant activity (10.68 µg mL^-1) followed by followed by V₂ – First best treatment of first experiment (Vertical split of mother rhizome) of Rajendra Sonia variety (12.62 µg mL^-1). Among the interaction effects between organic manures, biofertlizers and varieties, the treatment M₁V₁ – FYM 45 t/ha + AMC (Arka microbial consortium) 1 lit per quintal manure + vertical split of mother rhizome of Salem variety recorded maximum antioxidant activity (10.18 µg mL^-1) followed by M₃V₁–Vermicompost 14 t ha^-1 + AMC (Arka microbial consortium) 1 l q^-1 manure + First best variety of first experiment (Vertical split of mother rhizome) of Salem variety (10.51 µg mL^-1).
