Crop development of oil seed rape in the autumn determinates already two thirds of the potential yield in the following summer. In particular yield results of 2018 underline again, that what has been missed in the autumn hardly can be caught up in the spring. Thus, take care that your crops establish evenly and healthy in the autumn and develop a strong and healthy root system!
Only with an effective root system the current oil seed rape varieties can utilize their high yield potentials in a sufficient way. Thus, all possibilities have to be used to prevent early infections with clubroot. A starter fertilization with calcium cyanamide PERLKA® has proved to be extremely helpful in preventing clubroot as it suppresses the germination of clubroot resting spores in the soil. Furthermore slugs and the eggs of slugs react highly sensitive when exposed to this type of fertilizer. Thus, such a starter fertilization with calcium cyanamide PERLKA® perfectly accomplishes a molluscicide application after sowing and by this way offers best growing conditions for germinating rape plants even on fields with a well-known risk for slug damage.
Our recommendation: Apply 40 kg/ha of nitrogen in form of calcium cyanamide fertilizer PERLKA® directly before sowing. No incorporation and no waiting period is required. First yield results of 2018 confirm again: Such a starter fertilization with PERLKA® results in an extra yield of 200 to 500 kg/ha of seeds!
