Abstract: A field experiment was conducted at Malda Krishi Vigyan Kendra, old Alluvial Zone, Uttar Banga Krishi Viswavidyalaya, Malda, West Bengal, India during rabi season of 2019-2020 to find out suitable mustard variety and optimum spacing for three different varieties. Three varieties of mustard viz. V1- SitaV2- B-54(subinoy), V3- B-9(Vinoy)were taken as treatments in the main plot, whereas, four spacing – 30cm × 10cm (S1), 30cm × 20cm (S2), 40cm × 20cm (S3) and 40cm × 30cm (S4) were imposed as subplot treatment. The experiment was conducted in split plot design with 3 replications and repeated in rabi seasons for one year (2019-2020). The results of the experiment revealed that the maximum seed yield was recorded in B-9(Vinoy) 2153 kg /ha) followed by B-9(Vinoy) and then other varities. Regarding plant geometry significantly higher yield was noticed in 30 cm × 20 cm (1689 kg/ha). Crop geometry 40 cm × 30 cm observed superior with respect of number of primary branches/plant and seeds/siliqua, but it was not reflected on seed yield due to less number of plants per unit area. The hybrid varieties of mustard are highly suitable in old alluvial plains of West Bengal due to their higher yields. Slightly wider spacing (30 cm × 20 cm) is suitable variety because of their bigger plant canopy.
