Abstract:
The present investigation was conducted during the rabi season of 2021 at the Experimental Farm of the Faculty of Agricultural Sciences, DAV University, Jalandhar, to find out the effect of organic manures and bio-fertilizers on the growth and yield of radish (Raphanus sativus L). The experiment consisted of twelve treatments laid in RBD with three replications viz. T₁ (FYM @ 20 t/ha), T₂ (Vermicompost @ 5 t/ha), T₃ (Neemcake @ 2.5 t/ha), T₄ (Azotobacter @ 4 kg/ha), T₅ (Azotobacter @ 2 kg/ha + FYM @ 10 t/ha), T₆ (Azotobacter @ 2 kg/ha + Vermicompost @ 2.5 t/ha), T₇ (Azotobacter @ 2 kg/ha + Neemcake @ 1.25 t/ha), T₈ (PSB @ 4 kg/ha), T₉ (PSB @ 4 kg/ha + FYM @ 20 t/ha), T₁₀ (PSB @ 4 kg/ha + Vermicompost @ 5 t/ha), T₁₁ (PSB @ 4 kg/ha + Neem cake @ 2.5 t/ha), T₁₂ Control (RDF 70:50:50 Kg NPK). CR-45 variety was used for the experiment. Observations were recorded on number of leaves per plant, leaf length (cm), leaf area per plant (cm²), root length (cm), root diameter (cm), plant height (cm), root weight (g), fresh weight of plant (g), dry weight of plant (g), root yield per plot (kg/plot), TSS (◦Brix), ascorbic acid (mg/100 g) and benefit cost ratio. Analysis of variance (ANOVA) revealed significant differences among treatments for all the characters under study. It was concluded that with the application of vermicompost, better results in growth, yield and quality parameters were observed. Furthermore, with the application of vermicompost highest Benefit: Cost ratio was obtained.
