Field experiment conducted during rabi, 2017 at AICRP on Citrus, Citrus Research Station, Tirupati involved research on the effect of different plant spacings on yield and yield attributes of red cabbage. Plant density is an important variable for achieving maximum yields and uniform vegetable maturity. Optimal plant density can be achieved by establishing appropriate distances both between the rows as well as in the rows of plants. In this study, increasing the distance between plants caused an increase in number of heading leaves (19.57) with a low percentage of abnormal heads. However, there was no significant difference between different spacings regarding the number of loose leaves per plant. The most favorable parameters characterizing yield per plot (23.80 kg), marketable yield (183.69 q/ha) along with highest available soil N (157.47 kg/ha), P (44.36 kg/ha) and K (259.97 kg/ha) were found at closer spacing (45 x 45 cm).
