Potatoes are tubers that are widely planted throughout the world; they have good nutrition and play a role in food security (Ahmadvand et al., 2009; Karim et al., 2010). According to FAO data (2007), the average production of potato plants in Australia reached 35.9 tons per hectare, while potato production in Indonesia is lower at 18 tons per hectare. The low productivity of potatoes is caused by the limited use of high-grade potato seeds among Indonesian farmers. Such seeds are relatively expensive and seed costs involve the largest proportion of total production costs (Karim et al., 2010). It is estimated that in developing countries, the cost of procuring potato seeds makes up 40 to 70% of the cost of crop production (Masarirambi et al., 2012).
Potato seed production in Indonesia is still low due to climate constraints, pests and plant diseases; it is also due to the limited number of potato seed breeders. Generally, the breeders still use the conventional cultivation method, potato plants face insect and potato cyst nematoda problems in their growing area as well as worldwide (Malik et al., 2018; Mhatre et al., 2019; Priyank et al., 2019). Good-quality potato seeds can be obtained quickly and the result is high enough using aeroponic cultivation. Production technology of aeroponic potato seeds has started to be studied and used by some seed breeders in Indonesia in order to increase the production of potato seeds. Commercial production of aeroponic potato seeds has been developed in Korea and China. In South America, this technology has been used successfully since 2006 (Otazu, 2010). The aeroponic system in Peru’s International Potato Center (CIP) produces more than 100 mini bulbs per plant. The production of aeroponic potato tubers reached 1340 bulbs from 100 plants/m2 (Farran et al., 2006). In Indonesia, aeroponic technology has been developed. The result of financial analysis of the potato seed breeding business shows profitability with an R/C ratio value of 2.38, while the result obtained from the farmer breeder value is an R/C ratio equal to 2.08 (Tedy et al., 2011). Aeroponic technology in Indonesia is also being studied for application in lowlands with root zone cooling (Sumarni, 2013; Sumarni et al., 2013a, b, c; Sumarni et al., 2019). This technology is able to produce tubers of up to 14 tuber crops (Sumarni et al., 2013b). The production of aeroponic potato seeds producing 30-40 bulbs per plant in tropical highland (Sumarni et al., 2011). A potato seed tuber produced from aeroponic technology is a mini seed because it is grown inside a greenhouse and the root hangs in the air. Aeroponic potato seed production is profitable enough and produces a healthy seed because it comes from early seeds of tissue culture. However, how the quality of aeroponic seed to be the next seed (growing power) has not been further studied and informed scientifically.
Potato seeds are important in potato production (Rana et al., 2013). Poor potato seeds can reduce yields by 20% (Bentley and Vasques, 1998). The area of potato planting in the highland in Indonesia contains mostly endemic viruses and potato pests. Therefore, if the aeroponic potato seeds from the lowland and highland can produce advanced seeds, they can help the government reach self-sufficiency for seeds. This research aimed to obtain the effect of aeroponic seed yields from the lowland and highland based on their size on the growth and yield into advanced seeds.
