The present field experiment entitled “Effect of organic manures on growth yield and quality of Beetroot (Beta vulgaris L.) cv. Lali” was carried out during Rabi season of the year 2021-2022 at K.A.P.G. College, Prayagraj U.P. The result and conclusion of the about experiment are briefly explain here. The experiment was laid out in a randomized block design with 3 replication 11 treatments viz., T₁: FYM (100%), T₂: Poultry manure (100%), T₃: Green manure (100%), T₄: Neem cake (100%), T₅: Vermicompost (100%), T₆:FYM (50%) + Poultry manure (50%), T₇: FYM (50%) + Green manure (50%) T₈: FYM (50%) + Neemcake (50%), T₉: FYM (50%) + Vermicompost (50%), T₁₀: RDF, T₁₁: Control. The data were recorded on days required for germination of seedlings, plant height (cm), no of leaves per plant, crop growth rate (g m^-2 d^-1), root length (cm), root diameter (cm), root yield per plot (kg plot^-1), root yield per ha (t ha^-1), harvest index (%). The early germination was recorded in T₂: poultry manure (100%) and it was at par with T₉: FYM (50%) + vermicompost (50%) and vermicompost (100%). The highest plant height and no. of leaves was recorded with T₂: poultry manure (100%) which was at par with T₆: FYM (50%) + poultry manure (50%). The highest crop growth rate, was recorded with poultry manure (100%). Among the yield parameters the root length and harvest index were maximum with T₆: FYM (50%) + poultry manure (50%) whereas root diameter was maximum with poultry manure (100%). The highest root yield was recorded with T₂: poultry manure (100%) which was at par with T₅: vermicompost (100%). The highest N uptake in plant was recorded with FYM (50%) + vermicompost (50%). The highest P and K uptake in plant was recorded with poultry manure (100%). Whereas FYM (50%) in combination with neemcake (50%) recorded maximum values for betanin content reducing, non- reducing and total sugars. The highest TSS of root was with neem cake (100%). However, the higher net returns and BCR were obtained with poultry manure (100%).

The results of the present investigation revealed that among different organic manures tried, application of T₂: Poultry manure (100%) is reported higher plant growth, root yield, NPK uptake, maximum net returns whereas application of T₈: FYM (50%) + neemcake (50%) recorded better quality of beetroot.
