Dehumidifier boosts yields, cuts disease pressure and saves energy

A giant dehumidifier in cherry tomato grower Robert van Koppen’s greenhouse in Kwintsheul (Westland, the Netherlands) keeps the RH below the critical value of
We still know too little about flowering which is sometimes difficult when working with new crops. A lot of research has been carried out

Too little insight about factors that effect flowering

We know much more about photosynthesis than about the flowering of the plant. This sometimes leads to surprises, especially with new crops. The grower
A group of experts have now compiled all the available knowledge in this area in a book called “Vegetable grafting: principles and recent practices”.

Book about grafting fruiting vegetables

Levels of production of crops such as tomato and aubergine have increased in recent years with the use of rootstocks. In a number of
Dosing smaller amounts more often may improve the root environment, get the water and fertilisers circulating faster and reduce the risk of blockages.

Watering less more often: downsizing on trend in irrigation

The increase in scale that has been taking place over the past ten years calls for a different way of watering. Including on the
Grower Rob Olsthoorn of OK Plant deliberately opted for a triple screen for his new greenhouse so as to make it as closed an environment as possible.

OK Plant opts for triple screen to boost quality even further

A new online app quantifies the effect of radiated heat loss on crop temperature and energy loss from the greenhouse in a simple, user-friendly
A different growing strategy is a potential key to saving energy. An important part of this is to slow down transpiration.

Slowing down crop transpiration cuts energy consumption

The focus of energy savings usually lies in technology. But the crop itself offers numerous opportunities to economise on energy consumption. Many research results
The Precision Horticulture Programme was launched this year. It is a form of horticulture in which plants receive precisely the treatment they need.

Researchers have been working with screen manufacturers to develop an objective method of determining the energy saving performance of screen fabrics.

Energy-saving screens can now be compared objectively

Screen suppliers each have their own methods of determining the energy-saving performance of their screens, making it very hard for the grower to compare
Alstroemeria can get off to a good start with higher light levels than are generally used at present.
