Influence of production conditions on growth and development of kohlrabi (Brassica oleracea var. gongylodes L.)

Yield and quality of kohlrabi depends of genotype and agroecological conditions during growth and the best conditions are sunny, cold and wet areas. Germination of kohlrabi depends on environmental factors as well as vegetation growth which means that oxygen, water, optimal temperature must be presence and there must be abscense of inhibition factors. Regarding thessee facts during May 2011 experiment with two production conditions which vary in temperature and lightening has been carried on. Research has been conducted in greenhouse and hotbed of the University of Applied Sciences in Slavonski Brod using Vienna white and Vienna blue kohlrabi specieses, with 100 seeds sowed in plastic containers 3x3 cm in two repetitions in both production conditions. During the experiment germination showed significant correlation connection (r=0, 998** and r=0, 999**). Germination speed of Vienna white and Vienna blue also showed very strong positive correlation (r=0, 992** and r=0, 989**). Statistical data treatment showed no significant difference according germination energy and seed germination (P≤0, 01) depending on production conditions and cultivar. However other average values (length of roots, length of above ground part, length of transplant, mass of transplant) have been very significantly under influence of production conditions and mass of the transplants as well as length of the above ground was under influence of cultivar. In the average Vienna blue showed significantly higher values of above ground length and average mass of the transplant. Regarding our results we can conclude that in greenhouse quality of transplants is significantly higher than in hotbed which indicates on the importance of choosing the adequate production conditions for growth and development of kohlrabi.
