For Japanese people,
flavour and shape
are the most important criteria to select their tomatoes. The tests show an elevated level of sugar (glucose) and vitamin C as well as an increase in yield."
- Professor Toru Maruo, Chiba University
Conventional tomato cultivation use a method called ‘long-term multi-step cultivation’. But this method proves to be problematic due to the intensity of the labour. However ‘single-truss’ cultivation, which was employed in the current experiment, does not require much initial investment and uses space more efficiently also it is possible to control the whole production cycle up to harvesting.
The cultivation test was conducted twice for over a month each with a successful outcome. The test was carried out twice from February to April in 2012 in the testing greenhouse at Chiba University. In both tests, moving benches were being used to reduce installation cost and to simplify the labour. 15 plants were cultivated per square metre. For a period of one month at the fruit development stage, LED light was continuously irradiated for 16 hours each day from interlighting modules installed on both sides of the plants. The size and the sugar (glucose) and vitamin C contents of the fruits were measured upon harvesting, and comparative taste tests were carried out to assess the flavour. The results demonstrate the effectiveness of Philips GreenPower LED interlighting modules with regard to both yield and fruit quality.
Employing this cultivation method increases the possibility of being able to supply high-quality tomatoes at a market-competitive price.
The interlighting module is a bi-directional lighting module for interlighting in between tall plants e.g. tomatoes.
