By means of desiccation spreading of seed has been reduced, attack of different head parasites has been avoided, harvesting is easier and additional drying is not required. Negative effects of early frosts on germination could be avoided too. Desiccation is to be performed when seed moisture reach 40%, depending on genotypes. Optimal solution for desiccation are selfpropel sprayers with high clearence. Machine for cutting corn flowers with sprayers is also good solution. Tractor sprayers and airplanes could be use if necessary. All equipment for application must have appropriate nozzles. The best results have been obtained with Reglone forte (2 l/ha with 300-400 liter of water). Timely performed desiccation has no negative effects on yield, 1000 seed weight, germination, energy of germination, oil protein content and the husk percentage.
