Abstract

The influence of N and K level on the highness of leave epidermis and pathogenesity of Plrytopbthora infestant on the leave of potato. The expriment was conducted on laboratorium of Biology Departemen, Faculty of Matematcs and Natural Science. The result showed that combination amount of 0 kg N/ha with 0 kg KrOlha,and 180 kg N/ha with O kgkZO/ha shown the highest pathogenisity. The lowes showed of combination of 120 kg N/ha with 225 kg K20 /ha. The anaromocal view the combination amount of.60,720 and 180 kg N/ha with zZS kg kZA /ha shown the thicknees of leave epidermis. The thiness leave epidermis on combination of 180 kg N/ha with O and 75 kg K2Qlha.the value of regretion berween thickness of epidermis against the pathogenisitiy 'was - 0,656, that the more thicker of epidermis the lowest the pathogeniry on Potato leaves.
