“…Turning on only half of the lighting capacity during the first hour after dark can save significant amounts of energy in horticultural production systems. Näkkilä et al (2006) showed that varying the plant densities by interplanting is a possibility to increase light use efficiency in a tomato crop. They examined different planting densities (2.0 and 2.5 plants m -2 .…”

In intensive horticultural cultivation natural light levels often limit crop production during several periods. For an optimum plant production and product quality light intensity, spectrum and photoperiod have to be adapted to the needs of the crops at every moment. Light has to be optimised together with all other growth factors like temperature, humidity and CO 2 . For a sustainable greenhouse production the use of freely available sunlight has to be preferred. New transparent greenhouse covering materials, like ETFE, glass with new anti-reflection coatings or materials with micro-surface structures, transmit a very high amount of light into the greenhouse. Other new materials are able to scatter the incoming light and make it diffuse. Diffuse light penetrates deeper into the canopy, increases light interception by the crop, influences micro-climate and increases crop production by 6.5-9.2% in The Netherlands, the potential in lower latitudes is even higher. Other materials manipulate light spectrum. Photoselective nettings have been developed in different colours influencing morphogenesis and crop production. Fluorescent plastic films combine effects on morphogenesis with high light transmission, especially important for higher latitudes. When sunlight is optimized it can still be necessary to add artificial light to ensure a year-round supply of horticultural products. There is still room for improving the crop energy efficiency under artificial lighting by changing duration and intensity of lighting, different growing systems and plant densities. Since artificial lighting requires a high amount of energy, new artificial lighting systems have been developed, such as interlighting and light emitting diodes (LED). LED give the possibility for true light spectrum control in the future. The (partial) replacement of HPS lamps by LED systems is currently under investigation in Dutch greenhouses. Integration in current growing systems has full attention. In order to reach a high sustainable and economic beneficial production the factor light has to be integrated and optimized within the total horticultural system.

“…Interplanting is a cultivation method in which new seedlings are planted next to the old plants that are still being harvested (Dorais et al 1991). Previous studies reported a higher total fruit yield from interplanting (Avila-Juarez et al 2012;Miliev & Alexiev 1997;Nakkila et al 2006). However, interplanting may also cause succulent growth of new plants and increase incidence of stem lowering owing to shading by old plants.…”

We investigated the effects of interplanting on fruit yield in greenhouse-grown tomato by integrating the first (short) and second (long) crop periods in the cooler northern area of Japan. The marketable fruit yield was similar regardless of interplanting in the first crop period, whereas it increased with earlier planting dates in the second and total crop periods. Therefore, planting immediately after the harvest of the first fruit trusses of the first crop period was effective in achieving a continuous harvest and substantial yield improvement upon conclusion of the harvest of six trusses; moreover, there were no incidences of stem lowering in the first crop period. The plant dry weight was also similar regardless of interplanting in the first crop period. However, the total dry weight and fruit dry weight increased with early interplanting in the second and total crop periods. The marketable fruit yield and total dry matter production of the whole crop period increased when cultivation started in March compared with that in April. The dry matter allocation to the fruit was similar among the treatments in all crop periods. The total fresh and dry fruit yields were significantly correlated with the cumulative light interception over the total crop period. Therefore, fruit yield was the highest when cultivation started in March with interplanting in the early-summer resulting in the highest light interception and dry matter production.
