Effect of Different Planting Dates and Spacing on Growth Parameters of Cabbage (Brassica oleracea var. capitata L.)

Aim: To investigate the effect of various planting dates and spacing on cabbage growth.

Study Design: The experimental design Factorial Randomized Block Design (FRBD) was used.

Place and Duration of Study: An experiment was conducted in the rabi seasons of 2021–22 and 2022–23 at the Horticulture Research Farm, Babasaheb Bhimrao Ambedkar University, Lucknow (U.P.)

Methodology: There were twelve treatments with three replications. The variety selected for experiment was Pusa Mukta.

Results: The combined data of two years showed that treatment P1 (30 November) had significantly higher plant survivability (95.28%), plant height (14.67 cm, 21.31 cm and 28.39 cm) at 30, 45 and 60 DAT, respectively, stem diameter (2.11 cm), no. of non-wrapper leaves (16.28), no. of wrapper leaves (27.19), plant spread E-W (49.40 cm) and plant spread N-S (52.63 cm). Among spacings. The findings showed that the S4 (60 cm x 60 cm) plant spacing achieved maximum plant survivability at 91.59%. It also led to the greatest plant height at 30, 45 and 60 days after transplanting (DAT) with measurements of 15.73 cm, 22.45 cm and 31.12 cm, respectively. Additionally, this spacing resulted in the largest stem diameter (2.31 cm), the highest no. of non-wrapper leaves (17.40), no. of wrapper leaves (28.30), greatest plant spread in both East-West (52.79 cm) and North-South (56.08 cm) directions.

Conclusion: The results obtained from pooled data of two years showed that treatment P1 (30 November) and Spacing 60 cm x 60 cm had significantly higher growth parameters.
