Investigating light spectrum effects of LED inter-canopy lighting in greenhouse cucumber

Vine crops, specifically tomatoes and cucumbers, represent one of the largest segments for electric lighting in horticultural applications. Furthermore, cultivators are constrained by inadequate lighting conditions during winter months and ...

Does a diel cycle shorter than 24h or continuous light positively affect lettuce growth and light use efficiency; is this response genotype dependent?

Vertical Farming is a new model in food production with high water, fertilizer and land use efficiency compared to traditional cultivation. No pesticides are applied and since this novel system allows worldwide ...

Does light spectrum influence fruit set in sweet pepper?

Fruit set indicates the initiation of fruit growth derived from flowers, and the cessation of this process is termed as abortion. Fruit set is a crucial development process in the plant life cycle, and it is also a main determinant of crop yield. In sweet pepper, up to 80% ...

Developing a functional structural plant model of Artemisia annua

Artemisia annua is an important medicinal species. Its secondary metabolite, artemisinin, has been used in the treatment of malaria, as well as several cancers and viral diseases. In many developing and underdeveloped regions, artemisia plants are growing ...

Leaf boundary layer conductance: the final frontier for diffusion

Leaf-boundary-layer conductance (gb) represents the ease of diffusion through the air layer formed along the leaf surface due to reduced velocity and is mainly influenced by air speed. Under low air speed (e.g. within a plant canopy), gb is ...

Desk study: Is the use of interlighting in greenhouse production beneficial or wasteful?

In modern greenhouse production, plants are often grown in relatively tall, optically dense canopies –think of tomato, cucumber and bell pepper. Often, supplementary lighting installed above the plants (toplighting) is used to ...

About time: How light influences anthocyanin biosynthesis and stability in lettuce

Global food demand is increasing due to the growing human population and pushes breeding towards highly productive cultivars. As production increases, the nutritional quality (minerals and phytochemicals) of these crops usually ...

Vertical farming versus conventional farming: A comparative study

Vertical farming is an emerging practice consisting in cultivating crops under full LED conditions on vertically stacked layers which provides numerous advantages compared to conventional farming (i.e. greenhouses). Firstly, vertical farms ...
