Abstract:
The present investigation entitled “Studies on the effect of organic and inorganic nutrient management on yield and quality of beetroot (Beta vulgaris L.) cv. Detroit Dark Red” was carried out during Rabi season of the year 2021-22 at College of Horticulture, Rajendranagar, Sri Konda Laxman Telangana State Horticultural University. The experiment was laid out in Randomized Block Design (RBD) with thirteen treatments and three replications. Treatments consisted of T_1-Control (100% RDF), T₂-90% RDF + Vermicompost (2.5 t/ha), T_3-90% RDF + Azotobacter (10 kg/ha), T_4-90% RDF + Phosphorous solubilising bacteria (10 kg/ha), T_5-90% RDF + Azospirillum (10 kg/ha), T₆-70% RDF + Vermicompost (2.5 t/ha), T₇-70% RDF + Azotobacter (10 kg/ha), T₈-70% RDF + Phosphorous solubilising bacteria (10 kg/ha), T₉-70% RDF + Azospirillum (10 kg/ha), T₁₀-50% RDF + Vermicompost (2.5 t/ha), T₁₁-50% RDF + Azotobacter (10 kg/ha), T₁₂-50% RDF + Phosphorous solubilising bacteria (10 kg/ha), T₁₃-50% RDF + Azospirillum (10 kg/ha). Different have a significant influence on the yield and quality parameters of Beetroot. The yield parameters of beetroot were significantly affected due to different organic and inorganic nutrient management treatments. Application of recommended dose of fertilizers through combination of fertilizer and organic manures significantly increased the crop yield i.e., T₂ treatment (90% RDF + Vermicompost (2.5 t/ha) recorded higher values of yield attributes viz., root length (18.51 cm), root girth (9.17 cm), root weight per plant (189.93 gms), root yield per plot (11.58 kg) and root yield (28.95 t/ha). The quality of the beetroot root was significantly affected with different organic and inorganic nutrient management treatments. Application of recommended dose of fertilizers through combination of fertilizer and organic manures significantly increased the quality of the crop i.e., T₂ treatment (90% RDF + Vermicompost (2.5 t/ha)) recorded higher values of total soluble solids content in root (10.70 ⁰Brix), reducing sugars (1.75%), ascorbic acid content (4.82 mg 100 g fresh weight^-1) and recorded lowest percentage of root rotting (0.04%), percentage of root forking (3.41%) where minimum root cracking observed in T12 treatment (50% RDF + phosphorous solubilising bacteria (10 kg/ha).
