A combined conifer growth-soil water balance model was extended and parameterised to simulate the nitrogen (N) dynamics of a common nursery stock system [i.e., white cedar (Thuja occidentalis) grown for 2 years on a sandy soil]. The model was used to

The objective of the solar greenhouse project was the development of a Dutch greenhouse system for high value crop production without the use of fossil fuels. The project was completed and the results are reported here. The main approach was to first

Simulations in the authors’ previous studies have shown that a modified temperature integration regime with a 6-day averaging period and increased set-point flexibility was able to reduce annual energy consumption by up to 9% as compared to a regul

A simple method was developed to estimate the fraction radiation intercepted by small eastern white cedar plants ( Thuja occidentalis 'Brabant'). The method, which describes the crop canopy as rows of cuboids, was compared with methods used for estim

Some personal comments are given about research on supplementary lighting in horticulture. There is a rapid development in the use of supplementary lighting in horticultural practice. Generalisation is needed to share, transfer and apply the pertinen

In the present study, we used a photosynthesis-driven crop growth model to determine acceptable plant densities for cut chrysanthemum throughout the year at different intensities of supplementary light. Dry matter partitioning between leaves, stems,

Leaves are essential in the propagation of roses by cuttings. However, about the underlying principles, there is no unequivocal opinion in the literature. We investigated the hypothesis that current photosynthesis would represent the dominating facto
