| dc.description.abstract | One of the solutions for urban farming (urban farming) is hydroponic
cultivation, today the development of the world of agriculture, especially in the
field of hydroponics is increasing rapidly. The growth and production of tomatoes
with a good hydroponic system requires the right concentration and volume of
nutrients. This reaserch aims to analyze the effect of nutrient concentrations on the
growth phase of cherry tomatoes, to analyze the effect of nutrient concentrations
on the morphological and physiological responses of cherry tomato plants and to
analyze the effect of nutrient concentrations on hydroponic cherry tomato
production. This research used a completely randomized non-factorial design with
concentrations of nutrients, consisting of 5 levels: 800 ppm, 900 ppm, 1000 ppm,
1100 ppm and 1200 ppm. The results showed that nutrient concentrations had a
significant effect on the generative growth phase, but had no significant effect on
the vegetative growth phase of cherry tomato plants. Nutrient concentrations
affect plant physiology, namely: crown wet weight in the generative phase, root
wet weight in the generative phase, shoot dry weight in the generative phase, root
dry weight in the generative phase and levels of vitamin C. Nutrient
concentrations significantly affect the production of hydroponic cherry tomato
plants, the optimum dose to produce the highest fruit weight is at a nutrient
concentration of 930.91 ppm with a weight of 90.02 g. The use of nutrient
concentrations above 930.91 ppm can reduce fruit weight per plant, namely at a
nutrient concentration of 1100 ppm by 59.73 g and at a nutrient concentration of
1200 ppm by 55.70 g. There was an increase in fruit weight per plant by giving
nutrient concentrations of 800 ppm to 1000 ppm by 24.61%. | en_US |
