Abstract: The present investigation entitled to evaluate the effect of nutrient management on the growth and productivity of three different varieties of sugar beet (Beta vulgaris.) namely LKC-2000, Subhra and LS-6 in agriculture farm of NSI, Kanpur carried out during two consecutive years 2018-2019 and 2019-2020. The seeds were procured from Indian Institute of Sugar Cane Research, Lucknow. Ten treatments using different Rates of alternative (STR) and conventional (FP) fertilizers were take viz T1 as (Control) – N120P60K60; T2 as (FP) -N150P60K60; T3 as (100% STR) – N140P72K40; T4 as (125% STR) – N175P90K50; T5 as N150P60K60 (FP) + 5 t FYM; T6 as N150P60K60 (FP) + 1 t Vermi (FP); T7 as N140P72K40 (100 % STR) + 5 t FYM; T8– N140P72K40 (100 % STR) + 1 t Vermi; T9 as N175P90K50 (125 % STR) + 5 t FYM and T10 as N175P90K50 (125 % STR) +1 t Vermi. Results from the experiment revealed that use of 100% STR & 125% STR alone and along with standard dose of FYM and vermi significantly increased plant height, root length, root diameter, fresh and dry weight of root, root yield and nutrient uptake (NPK) of sugar beet than sole use of NPK ie control (T1) as well as FP (T2). All the three varieties of sugar beet similarly responded to the treatments but LKC-2000 and Subhra responded comparatively best than LS-6 variety. LKC-2000, gave the highest value of total reducing sugar (18.29%) followed by Subhra (17.95 %) & LS-6 variety (17.60 %). LKC-2000 gave ethanol yield of around 129.4 AL/ton followed by Subhra with 119.6 AL/ton and LS-6 with 101.26 AL/ton.
