Abstract
Early and later maturing cultivars of both spring- and autumn-sown onions were sown on two dates at 25, 100 and400 plants m−2. High levels of nutrients and irrigation were applied. Both high plant density and early sowing advanced the date at which bulb scales, rather than leaf blades, were initiated at the shoot apex and so advanced the date of maturity by up to 46 d. The later maturing spring-sown cultivar showed greater responses to density and sowing date than the earlier maturing spring-sown cultivar which in turn was more responsive than the autumn-sown cultivars. For each cultivar, maturity date increased linearly with decreases in the percentage radiation intercepted by the leaf canopy.

Claim · model-written summary
The later maturing spring-sown cultivar responded more to density and sowing date than the earlier cultivar, which responded more than autumn-sown cultivars.
