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.
