THE EFFECT OF CULTIVAR AND PLANTING DATE ON THE YIELD AND QUALITY OF WHITE CABBAGE GROWN IN SUBMONTANE REGIONS

The submontane region of Poland shows favourable conditions for the production of cabbage crops.
In Podkarpacie region (Carpathian Plateau) four cultivars of cabbage: Lennox F₁ (Bejo Zaden), Galaxy F₁ (Royal Sluis), Marathon F₁ (Sluis & Groot), and Kamienna Glowa (a local cultivar) were compared at two planting dates (8 May 1992 and 18 May 1993; 26 May 1992 and 5 June 1993, respectively).

The high marketable yield obtained (63,88–107,41 t/ha) confirmed the value of the submontane region for cabbage production.
The highest marketable yield was recorded in the case of Kamienna Glowa (76,20–105,92 t/ha) and Lennox F₁ (78,05–107,41 t/ha), followed by Galaxy F₁ (70,46–104,24 t/ha) and Marathon F₁ (63,88–89,40 t/ha). The delayed planting dates brought about a significant decrease in yields of the investigated cultivars in 1993 only, excepting Kamienna Glowa.
Dutch cultivars were characterized by a very high quality of the crop and a great percentage of marketable yield in the total one (95,2–99,1%). For Kamienna Glowa it amounted to 74,9–96,0 % on average.
Lennox F₁, Galaxy F₁, and Marathon F₁ were also characterized by a greater content of dry weight, sugars before and after inversion, and in most cases also of protein than that assessed in Kamienna Glowa.
A larger content of all the analysed components was found in heads of cabbage planted at the earlier date with the exception of protein for which no such dependence was documented.
