3.4. Results of the organic fertilizer testing in the vertical farming
After applying organic fertilizer for 3 consecutive cultivation seasons in the

greenhouse, the results were recorded: The average biomass yield and the average
commercial yield (Counting by kilograms per square meter of cultivation space) in each
crop was not significantly different; At the same time, compared to the pilot results, this
test results also showed similar results (Table 5).

The results of vertical farming in greenhouses were also compared with the results
of traditional farming in the field for 5 types of experimental vegetables (Table 6).
Accordingly, in terms of the space occupied by the farming model, the vertical farming
2
model is considered more effective than traditional farming. Specifically, on 1m of
space with the vertical model, 120-234 plants can be grown (1.8m high pillar model –
Fig.1; and 2.1m high pillar – Fig.2), while in the field, this number is 42 plants.

Therefore, the total vegetable yield per unit area/crop in the vertical model will be higher
than that of traditional farming, such as: Commercial yield of the Green mustard in

2
greenhouse is 26.580 kg/m compare to 19.140 kg/m in the field; and similarly, the
experiment of 4 vegetable varieties also have higher yields when grown on vertical
poles and in greenhouses (Table 6). In addition, farming in greenhouses will be carried
out all year round, regardless of weather and climate; At the same time, fertilizers and
pesticides are also controlled to meet the requirements of quality standards for

agricultural products.
