Vermicompost increasingly is used in crop technology, especially in organic farming production system. In order to be able to embed mechanized vermicompost, using a combined planting and sowing machines, it is granulated to improve the flow ability of fertilizer. The study aims - to find out how the effect of powdered and granular vermicompost on potato yield and harvest substructures. The experiment was arranged from 2013 to 2015 on farm ''Pilsumi'', Aloja parish, Aloja Municipality, comparing the two-component herbal vermicompost, which differ in physical and technological characteristics and were as powdered and granulated product, and they shall have been obtained in order from one successor and the same raw material (manufacturer Ltd. "Ekotri"). Using vermicompost, irrespective of its form, after the physical and technological features all try vermicompost dose versions of potato varieties 'Adretta', 'Bellarosa' and 'Imanta', compared with the control, got the potato tuber yield increase. Powdered form vermicompost highest potato tuber yield provided a dose of 60 grams per tuber and compared to control treatment resulting tuber yield increase was 60% cultivar 'Bellarosa', 80% of the variety 'Imanta' and 87% of the cultivar 'Adretta'. Granulated form vermicompost highest tuber yield of potato variety 'Bellarosa' provided with a dose of 40 g per tuber (relative yield increase over the control of 35%), but the species 'Adretta' and 'Imants' - with a dose of 60 grams per tuber (relative yield increase compared a control were respectively 57% and 54%). Comparing the efficiency of powdered vermicompost with granular product, the highest tuber yield and productivity growth habit got potatoes using a powdered product.
