In the submontane conditions of southeastern Poland six Dutch cauliflower cultivars planted out for autumn harvest on two plantig dates were investigated. The average weight of curds, the structure of total yield (quality grades I and II and unmarketable curds), diameter classes of curds (A, B, C, D), and also their chemical composition (dry matter and protein) were taken into consideration. Analysis of cauliflower quality confirmed the production potential of the submontane region in the case of this species. The highest average weight of curds was obtained from hybrid cultivars (1.39-2.40 kg) and the smallest from the standard cultivar Ostrea (1.08-1.60 kg). Analysis of the structure of total yield showed a very high percentage of Grade I (64.4-95.8%). This was characteristic above all of White Ball and Batsman and also of hybrid cultivars especially in the later growing season (turn of June) when the conditions were favourable for the growth of this species. The high quality of the cauliflower crop was confirmed by the measurement of the size of curds on the arch. In commercial yield a diameter exceeding 25 cm (class A) was found in 41.4-94.5% of curds, with the hybrid cultivars (particularly Plana F1) approximating to higher values. The earlier growing season was more favourable in respect of this trait.
