Abstract
Four cultivars and several breeding lines of storage cabbage were grown by direct seeding and by transplanting over 2 seasons. Weights and densities of heads harvested at successive intervals in conjunction with heat units and available solar radiation yielded estimates of the time to maturity and the mature time interval in the field before splitting is likely to occur. Most cultivars of storage cabbage are ready for harvest when they have attained a density of 0.72–0.80 and a weight of 2.2–3.0 kg which corresponds to accumulation of 1000 to 1050 C heat units (10°C base) and 50,000 to 5000 gm/cal/cm2 solar radiation units. The interval between maturity and splitting varied from less than 1 week to more than 6 weeks depending upon cultivar and weather conditions.
