Abstract: Entitled as “Influence of seaweed extract on growth, yield and quality of onion cv. Sukhsagar”, a study was designed and well performed at HRS, Mondouri, BCKV, under NAZ of West Bengal, throughout November – March of two consecutive years (2020-2021 and 2021-2022). The exploration was set up in RBD accompanied with 10 treatments of 3 replications viz., (T1- seed treatment with SWE (20%) @ 1ml l^-1, T2 - seed treatment with SWE (20%) @ 1.5 ml l^-1, T3 - seed treatment with SWE (20%) @ 2ml l^-1, T4 -seed treatment + root dipping with SWE (20%) @ 1ml l^-1, T5 - seed treatment + root dipping with SWE (20%) @ 1.5ml l^-1, T6 - seed treatment + root dipping with SWE (20%) @ 2ml l^-1, T7 - root dipping with SWE (20%) @ 1 ml l^-1, T8 - root dipping with SWE (20%) @ 1.5 ml l^-1, T9 - root dipping with SWE (20%) @ 2 ml l^-1and T10 - control (seed and root dipping in distilled water). The concentrated combination for the treatment were subjected to mean maximum plant height (63.40 cm), leaf length (61.70 cm), leaf width (3.35 cm), neck thickness (3.55 cm), no. of leaves plant^-1 (5.80), bulb yield plot^-1 (4.18 kg), projected bulb yield (16.93 t ha^-1), dry matter content (8.52 %), TSS (11.63º Brix), titratable acidity (0.42 mg 100^-1), ascorbic acid (8.01 mg 100^-1), total sugar (12.70 %), reducing sugar (4.54 %), net profit (Rs. 201608 ha^-1) and B:C ratio (1.95:1) was evident underneath T6 ( seed treatment + root dipping with SWE (20%) @ 2ml l^-1).
