The manifestation of certified and farm seed potato
TROPPOVÁ, Halka
Thesis aims to evaluate the performance of certified and farming potato seed cultivars of Red Anna and Monika. Following aspects were evaluated: number of full-grown, tuber yield, the average number of tubers in a bunch, the average weight of tubers in a bunch, the average weight of one tuber and starch content. The experiment started in 2013 on the farm of Ing. Tomáš Dušička in Plasy. In the experiment there were used cultivars of Red Anna and Monika because of good reputation. Certified seed was used in reproduction level C2, farmer seed was gained in the same location. Tubers were planted on the 5th May 2013, using two row seed planter (row spacing 75cm and tuber distance 25cm). Tubers were planted in the height of 16cm. In the planted rows of field experiment there was marked area of 10m2 per repetition, which requires 45 full-grown bunches in the plot. Harvest of experimental plots was carried out manually since 15th to 17th September 2013. Each bunch was dug, then the total number of tubers in a bunch was counted. Finally, the whole bunch was weighted. Tubers were sorted into two categories by size using sieve (mesh size 40mm). Both categories were weighted. Study results reveal that in the first year of planting of own farm seed may not significantly affect the yield and starch content. In case of farm seed of Monika cultivar there was 12% increase in revenue and slightly higher yield of tubers for consumption.
