Response of Cabbage To Plant Spacing, Nitrogen and Phosphorus Levels

A study was made on the influence of plant spacing (45 × 30, 45 × 45 and 45 × 60 cm), levels of nitrogen (60, 120, 180 and 240 kg/ha) and phosphorus (30, 60 and 90 kg P₂O₅/ha) on the yield and its attributes of the cabbage variety Pride of India on sandy loam soils at Ranchi during the years 1984–85 and 1985–86. The closest spacing 45 × 30 produced significantly higher number of marketable heads which, resulted in highest yield in both the years. The head weight was maximum at 45 × 60 cm spacing. Nitrogen application at 180 kg per ha significantly increased the yield and number of marketable heads. Application of phosphorus at 60 kg P₂O₅ per ha recorded the highest yield, average head weight and number of heads per hectare.
