Abstract
Aeroponic cultivation has emerged as a promising technology for improving potato minitubers production under controlled conditions. This study evaluated the effects of three cultivation systems (aeroponics, hydroponics, and conventional cultivation) and four potato genotypes (Azaria, Brasovia, Cosiana and Cezarina) on plant growth and minitubers production. Plant height, number of minitubers per plant and minitubers weight per plant were assessed. Analysis of variance reveals a statistically significant effect of the cultivation method on plant height at one month (p < 0.01) and a highly significant effect on plant height at two months, as well as on the number and weight of minitubers per plant (p < 0.001). The variety has a statistically significant effect on plant height at one month (p < 0.01) and a highly significant effect on the other parameters analyzed (p < 0.001). The interaction between cultivation method and variety is insignificant for plant height at one month (p > 0.05), but becomes highly significant for plant height at two months and for production traits (p < 0.001), indicating a differentiated response of the varieties to the conditions specific to each cultivation method. Hydroponic cultivation stimulated early plant growth one month after transplanting, whereas aeroponic cultivation resulted in the greatest plant height two months after transplanting. The aeroponic system also produced the highest number of minitubers (37.26 per plant) and the greatest minitubers weight (357.11 g per plant), significantly exceeding both hydroponic and conventional systems. Among the evaluated genotypes, Cosiana, Brasovia and Azaria showed superior minitubers production compared with control cultivar Cezarina. The results demonstrate the high potential of aeroponic cultivation for efficient potato minitubers production and support the implementation of advanced soilless technologies.
