Experience in aeroponic technology for potato seed propagation in the Czech Republic

Popis výsledku v původním jazyce

Aeroponics is a method of growing plants in an aerial or foggy environment without the use of soil or aggregated nutrient medium (Farran and Mingo-Castel, 2006). Aeroponics would appear to have a number of potential attributes to make potato production more efficient (Christie, Nichols, 2004). For potatoes it is used especially for the breeding and potato seed multiplication. This paper presents two years experience in the use of aeroponic technology for the production of seed potato minitubers in Potato Research Institute Havlickuv Brod, Czech Republic. We used plant tissue cultures of three potato varieties – Adela (early), Zuza (medium early) and Ornella (medium late). Plant density was 25 plants.m2. The nutrient solution specifically designed for aeroponics (1) and solution by Otazú (2010, 2) were used. In 2019 and 2020 years in the aeroponic unit minitubers weighing more than 1 g (sizes 10 – 30 mm) were harvested until the aging of the crops (104 - 130 DAP) at weekly intervals. In 2019 plants fed a solution for aeroponics formed more tubers per plant (Adéla 5,3 pcs, Zuza 7,2 pcs, Ornella 4,2 pcs) compared to plants nourished with Otazú solution (Adéla 2,4 pcs, Zuza 3,8 pcs, Ornella 2,5 pcs). However, this difference was not statistically significant. In 2020 the number of tubers per plant ranged from 14,4 pcs for the Ornella in solution 2 to 19,5 pcs for the Ornella in solution 1. For the Adéla, the number of tubers per plant in solution 2 was 14, 7 pcs. In a special solution 19,2 pcs. Zuza had numbers of tubers 17,7 pcs (Solution 1) and 18,5 pcs (Solution 2). A statistically significant effect of the nutrient solution was demonstrated for the Ornella and the Adela variety in both nutrient solutions. Statistical significance was further found for solution 1 for the Adéla to the Ornella and for solution 2 for the Ornella to the Zuza and Adéla. When comparing the effect of nutrient solution composition on the number of tubers between years (2019 and 2020), a statistically significant effect of both nutrient solutions in 2020 compared to 2019 was demonstrated. In 2020 a significant increase in tuber growth was achieved in all evaluated potato varieties.
