Abstract:
The present investigation entitled “Standardization of organic cultivation practices on quality in bitter gourd (Momordica charantia L.) var. Pusa Aushadhi” was carried out during rabi season in the year 2021-2022 at P.G research farm, College of Horticulture, Rajendranagar, Hyderabad. Sri Konda Laxman Telangana State Horticultural University. The experiment was carried out with twenty (20) treatments in Randomized Block Design with three (3) replications i.e. T₁: Farmyard manure (25 t/ha) + AMC (12.5 kg/ha), T₂: Farmyard manure (25 t/ha) + VAM (10 kg/ha), T₃: Farmyard manure (30 t/ha) + AMC (12.5 kg/ha), T₄: Farmyard manure (30 t/ha) + VAM (10 kg/ha), T₅: Vermicompost (10 t/ha) + AMC (12.5 kg/ha), T₆: Vermicompost (10 t/ha) + VAM (10 kg/ha), T₇: Vermicompost (12 t/ha) +AMC (12.5 kg/ha), T₈: Vermicompost (12 t/ha) +VAM (10 kg/ha), T₉: Poultry manure (6 t/ha) + AMC (12.5 kg/ha), T₁₀: Poultry manure (6 t/ha) + VAM (10 kg/ha), T₁₁: Poultry manure (8 t/ha) + AMC (12.5 kg/ha), T₁₂: Poultry manure (8 t/ha) + VAM (10 kg/ha), T₁₃: Neem cake (1 t/ha) + AMC (12.5 kg/ha), T₁₄: Neem cake (1 t/ha) + VAM (10 kg/ha), T₁₅: Neem cake (2 t/ha) + AMC (12.5 kg/ha), T₁₆: Neem cake (2 t/ha) + VAM (10 kg/ha), T₁₇: RDF (40: 80: 50 NPK kg/ha) + AMC (12.5 kg/ha), T₁₈: RDF(40: 80: 50 NPK kg/ha) + VAM (10 kg/ha), T₁₉: RDF (40: 80: 50 NPK kg/ha), T₂₀: Absolute control. Different treatment combinations of RDF and organic manures along with bio fertilizers have a significant influence on quality. The results on quality parameters indicated that among all treatments, T₁₁: Poultry manure (8 t/ha) + AMC (12.5 kg/ha) recorded significantly lowest fruit pH (6.54), highest TSS (5.18 ⁰Brix), highest ascorbic content (107.11 mg/100 g) and highest chlorophyll content (1.59) compared to the other treatments.
