COMPARISON OF NUTRIENT UPTAKE BY GROWING MUSK MELON BETWEEN IN HYDROPONICS AND IN TRADITIONAL SOIL CULTURE

The fluctuation of nutrient uptake by netted musk melon, Earl’s Favourite grown in hydroponics was compared with that in traditional soil culture in order to improve the defects in the plants produced in hydroponics.

The nutrient uptake after pollination was severely depressed in soil culture while not in hydroponics.
When the nutrient supply after pollination was controlled in hydroponics like as in soil culture, a part of defects in plant growth was improved; depression of excessive development in upper leaves, uniform appearance of a net on the fruit surface and improvement of the low content of the soluble solid in the fruit juice.
Disease infection was also remarkably reduced by controlling nutrient uptake.

The regulation of plant growth by controlling nutrient supply with the fruit development in the same way as in traditional soil culture seems to be essential to yield high quality one in hydroponics.
