<div>Background: Potato seed production with aeroponic technology can produce a large number of seeds, besides that it is also healthy because it uses plant seeds from tissue culture. However, how the quality of aeroponic seeds produced to become the next seed (growth capacity) has not been studied and scientifically informed. This research aimed to obtain the effect of aeroponic seed yields from the low and high plains based on their size on the growth and yield into advanced seeds. Potato seeds used were from the highland and lowland using aeroponic technology.&nbsp; 
 
Methods: This research was conducted in the highland (1000 m above sea level) from April to July 2017. Seeds were classified as S &le; 1 mg, 1 &le; Md &le; 10 g and L &ge; 10 g. This research used a randomized block design with seven repetitions. The tried factors were as follows: 1. The origin of aeroponic seeds (A): A1 (lowland), A2 (highland); 2. The size of aeroponic seeds (U): U1 (S), U2 (M), U3 (L). Plant growth parameters included plant height, number of leaves and number of tubers.&nbsp; 
 
Result: The data obtained were analyzed using Duncan&rsquo;s Multiple Range Test (DMRT) at the 5% level. Seeds of aeroponic yields of various sizes that are planted using drip irrigation have the potential to become advanced seeds. The L-size aeroponic seeds from the lowland produced an average of 5.9 tubers with an average weight of 68.4 g.</div>

<div>Background: The agricultural sector is highly dependent on the availability and quality of seeds for a productive harvest. The global demand for food and water is expected to increase due to population outgrowth, urbanization and climate change. Soilless farming may change the face of agriculture by providing a more sustainable and productive alternative to traditional cultivation and is being largely exploited for vegetable cultivation.&nbsp; 
 
Methods: The experiment consisted of 12 treatments. Two parental lines (P1: TAG 1 and P2: TAG 2) were subjected to seed treatment (S1: Untreated and S2: Thiram @ 2g kg-1 and chlorpyrifos @ 3g kg-1) and twenty-eight days old seedlings were transplanted to soil (M1: Conventional) and soilless systems (M2: Hydroponics and M3: Aeroponics). Hybrid seeds were produced in all the system were analysed for the quality and economics of seed production in soilless system was worked out. 
 
Result: The results revealed that there was a significant increase in test weight (0.39 g), average seed length (0.52 cm) in the soilless system due to the continuous availability of nutrients at controlled condition. Although the cost incurred was comparatively higher in the soilless method, the gross return was 94.68 per cent higher under aeroponics and 79.22 per cent higher under hydroponics compared to the conventional method. The benefit to cost ratio was found higher in aeroponics (2.08) followed by hydroponics (1.97) and lower under the conventional method (1.87). It is inferred that soilless agriculture could be a promising tool for quality and healthy hybrid tomato seed production throughout the year within protected cultivation.</div>
