Description A preliminary study was undertaken to compare the effect of different planting densities on seed yield and seed quality of pak choi (Brassica rapa L. subsp. chinensis L.) at the research farm of CPCT/ Division of Seed Science and Technology, ICAR-IARI, New Delhi during rabi 2019-20. Four plant spacing’s viz., 60 x 45 cm, 60 x 30 cm, 45 x 30 cm and 30 x 30 cm were attempted to assess the effect on the growth, yield and seed quality attributes. The result exhibited that seed yield and yield attributes, namely plant height (88.8), number of primary branches per plant (6.3), number of secondary branches per plant (9.1), number of tertiary branches per plant (8.2), there were no silique on primary branches but the number of silique on secondary branches per plant (110.4) and tertiary branches per plant (45.2), number of seeds per silique (26.5), seed yield per plant (45.1 g) seed yield per secondary branch per plant (37 g) and per tertiary branch per plant (8.1 g) were found highest in spacing of 60 x 45 cm, but seed yield per hectare (2.14 t/ha) was found highest in spacing of 60 x 30 cm mainly due to higher plant population per hectare and optimum resource utilization in field per unit area. Seed quality attributes, such as 1000 seed weight (1.81 g), germination percentage (96 %), seedling vigour index I (663) and seedling vigour index II (18.9) were found highest in spacing of 60 x 30 cm. These investigations indicated that relatively better performance was observed in medium plant densities over higher and lower ones, particularly with respect to seed yield per hectare as well as seed quality attributes. Thus, it can be concluded that Pak choi should be planted with a spacing of 60 x 30 cm for higher seed yield and quality.
