How do you achieve the highest yields with your lighting system? As we know, increasing light intensity up to a certain species-specific point, results in a corresponding increase in yield. And when light levels are not optimized for production, or the type of crop you are growing, you are going to have slower flowering, poor root development and plant structure, as well as reduced yields. There ...
The ornamental horticultural industry is diverse and made up of flowering potted plants, cut flowers and bedding plants. Ornamentals have specific lighting requirements needed to grow high quality and consistent crops. Since many bedding plant varieties are started in winter, lighting becomes important for managing early growth stages and to ensure products are in a condition ready to be shipped ...
Pepper, tomato and cucumber crops require consistent levels of light for year round production. There are many things to consider before investing in a lighting solution and understanding your growing environment – and the goals you want to achieve – will help in choosing a system that best suits your needs. Having a reliable and efficient lighting system is important not only for ...
Getting a good crop canopy across the entire field is important for better crop quality and higher yield. ...

Images taken with this state-of-the-art equipment detect wavelengths of light both within and outside of the visible spectrum, allowing these cameras to “see” into crop canopies. Many of these images, thanks to the resources of NASA and the European Space Union, are made available in massive public repositories. ...
In northern climates many growers rely on the heat from HPS to warm their crops. • Canopy Penetration This is a big consideration to consider when comparing these technologies. There is no easy math to calculate an ROI for this but when comparing light plans from one source of light to another be sure to take into consideration the distance of the light ...
Strategy for Adding Lighting to Booms Instead of installing stationary lighting within your greenhouse, a common practice is to install lights on irrigation booms. As they move across the crop canopy, the number of bulbs needed is reduced as they achieve daylight extension or night interruption through a moveable boom. ...
They used 16 prototype wireless sensors on a center-pivot irrigation system to monitor crop canopy temperatures. They chose sorghum because of its importance as a cash crop in the Southern High Plains and because it withstands water stress. Even so, irrigation plays a significant role hi sorghum production in the region, tripling its yields. ...
Nitrogen available to support corn (Zea mays L.) production can be highly variable within fields. Canopy reflectance sensing for assessing crop N health has been proposed as a technology to base side-dress variable-rate N application. Objectives of this research were to evaluate the use of active-light crop-canopy reflectance ...
The temperature and vapor pressure deficit (VPD) of the air were measured at the crop canopy level and above and below the canopy. Changes in maize canopy temperature, transpiration, and leaf water potential (LWP) were determined. ...
The focus of this study was to evaluate the potential of improving N recommendations based on crop canopy reflectance. Corn was grown at four field sites in each of 2 yr in Centre County, Pennsylvania. ...
Active canopy sensors can be used to assess corn (Zea mays L.) N status and direct spatially-variable in-season N application. The goal of this study was to determine optimal sensor spacing for controlling whole- and/or split-boom N application scenarios for a hypothetical 24-row applicator. Sensor readings were collected from 24 consecutive rows at eight cornfields during vegetative growth in ...
However, daytime sprinkler irrigation modifies the microclimatic conditions within the crop canopy which could result in improved crop growth. We studied the effect of daytime and nighttime irrigation on the growth and yield of maize (Zea mays L.) irrigated with a solid-set sprinkler system. ...
