Project Details

Description

This project is aimed at the optimization of a vegetable crop based on the available scarce winter light. The aim is to plant a crop that can intercept and utilize the (winter) light with a minimum leaf quantity. A minimum amount of leaf means the most efficient use of available assimilates for the fruits and the least possible loss of assimilates to crop formation and loss of energy due to (unnecessary) crop evaporation. With this the objective is both energy saving and production increase.

As an example crop, a high wire cucumber culture was chosen and the high-insulating 2SaveEnergy greenhouse was used as a test greenhouse. This greenhouse was built last season and in 2015 tomatoes are grown here as a trial crop. The 2SaveEnergyKas is a greenhouse with diffuse glass and a permanently available high-light transmissive film layer parallel to the glass. The greenhouse is equipped with a dehumidification system with outside air via sluices under the gutter.

The crop control is done both by variation in row width, plant distance and through crop control by picking young leaves (in the head) and fruit thinning. The optimum is predetermined by model. During 2 crops in the year the light interception, the cultivation (crop, production and quality) and the energy consumption are intensively monitored.
