Effect of Different Spacing and Time of Planting on Growth and Yield of Chinese Cabbage (Brassica rapa) under Prayagraj Agro Climatic Condition

A field experiment was conducted during the Rabi season in 2022-23 at vegetable research farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences, Prayagraj (UP). The experiment consisted of nine treatments combinations with three plants spacing viz. (i) 30 x 45cm, (ii) 45 x 60cm and (iii) 45 x 45cm and three levels of sowing date viz. (i) November 5th 2022, (ii) November 12th 2022, (iii) November 19th 2022, were included in the study in Randomized Block Design with three replications. The growth, yield and quality contributing all characters were significantly influenced by the treatments. The highest plant height, number of leaves, weight of head per plant, chlorophyll content and length of outer leaves (cm) as recorded in T6 (D2S3) (plants sowing November 12th 2022 with spacing 45 x 45cm) followed by T3 (D1S3) and lowest in T7 (D3S1). The maximum weight of head per m2, yield per plot (79.6kg) and yield per hectare (89.1t ha) were recorded -1 in T4 (D2S1) (plants sowing November 12th 2022 with spacing 30 x 45cm) followed by T1 (D1S1) and minimum weight of head per m2, yield per plot (35.6kg) and yield per hectare (199.0 t ha-1) were recorded in T8 (D3S2) of Chinese cabbage.
