To investigate the impact of growth and physiological aspects of Knol khok (Brassica oleracea var. gongyloides) cv. Early white, an experiment using a randomized block design was carried out in 2022 at the Horticulture orchard, Faculty of Agriculture, Annamalai University, Annamalai Nagar, Chidambaram, Tamil Nadu. In this study, the Knol khol crop were grown in late Rabi season which had a fluctuations in temperature getting raised. Different plants were selected from plot to study the varies growth and physiological traits of knol khol. The results reported that the growth parameters like plant height (cm) at 25 and 45 DAT, leaf length (cm), leaf width (cm), leaf area (cm²). fresh weight (g), dry weight (g) shown the variation except in no. of leaves and physiological parameters like leaf area index at 25 and 45 DAT, leaf area ratio (cm2 g-1), leaf area duration, specific leaf area (cm² g^-1), specific leaf weight (mg cm²), and leaf weight ratio (gg^-1) observed the variations between the plants in these parameters except absolute growth rate (cm day^-1). Despite being a cool season crop, knob formation is halted and increased the vegetative growth as a result of ring temperature.
