A Study on Single-Truss Tomato Production by Hydroponics(1)-Plant Growth and Fruit Yield by Different Sowing Dates Over the Year

Shoji KOBAYASHI

Summary

    Single-truss tomato plants(cv.'Momotaro','House-Momotaro', and 'Multi-First') were grown on rockwool cubes in a green-house by several sowing dates over the year. Plant growth was good and the percentage of fruit of each variety was about 90%.
    The number of days from sowing to flowering, from flowering to the start of harvest and from the start to the end of harvest varied depending on the growing season. As the mean period from flowering to the end of harvest in 'Momotaro' was 68.6 days, it was estimated that single-truss tomatoes could be grown 5 times a year.
    Estimated annual fruit yields by combination of high quality varieties, 'Momotaro'(sowed in January to September) and 'House-Momotaro'(sowed in October to December) was 36t/10a and exceeded 50t/10a by 'Multi-First', a high yield variety.
