Watering Greenhouse Tomatoes
with Energized UMH-Water
Starting Date of Experiment: 06-01-1997
End Date of Experiment: 09-30-1997
Distance between plants: 90 x 50 cm = 2.2 plants per sq. meter
8 varieties tested, watered with and without treated water
The identical amount of water was used for both varieties tested; also the same amounts of fertilizer were used. Previous to planting we worked a small amount of horse manure into the soil. The mineral content (N-P-K) was achieved as required.
At the beginning and end of July, further liquid fertilizer was applied via the drip irrigation system. Watering was carried out via drip irrigation (FX-Agrodrip) with dripping at a distance of 33cm. We measured the dampness of the soil using plaster blocks whereby the drip irrigation was turned on by a device at intervals of between 50 and 60.
The average amount of water was between 18 and 20 liter per m² with watering between every 3 to 6 days (depending on precipitation). All varieties watered with energized water showed an average yield of 11.8% higher. The individual kinds however showed highly varying results. This situation made it necessary to clarify these varying result through further testing. As regards the quality of the fruit (color, firmness, surface features, taste) there were no noticeable differences.
Distance between plants 90 x 50 cm = 2.2 plants per sq. meter
10 varieties tested; 16 plants watered with and without treated water
The same amount of water was used in all varieties tested
The moisture level of the soil was measured with plaster blocks to determine water amounts
Fertilization:
Varieties E and N were fertilized with 61 N-P-K horse manure per m²
2x liquid fertilizer with Hakaphos 0.2 % via drip irrigation
In general all varieties watered with energized water showed an increased yield of 13.4% per piece; the weight per piece increased by 3.6 g; an additional 3.03 pieces were harvested. The individual varieties however showed greatly varying results in growth. This condition was already noted in the results of the 1997 experiment.
This may result from differences in earth banks or varying absorptive capacity of the root systems of individual sorts.No pronounced differences in the qualities of the fruit (coloring, firmness, surface features, taste) could be determined;
several sorts grew with increased strength and bloomed more powerful.
