This paper describes the development of software (EOM) to provide a tool for commercial growers in order to determine the site-specific effects of energy saving investments. Results consist of energy use, crop production and an extensive economic overview. The core of the software is a scientific model (KASPRO) which simulates the greenhouse climate accurately and computes the resulting energy ...

A numnber of authors have recommended the use of photometric apparatus for determining leaf area, and at least 1 commercially-manufactured instrument is available. In principle the leaf is placed between a light source and a photocell or battery of photocells: the reduction in photocell output due to the presence of the leaf then gives a measure of leaf area. The transmission of light through t...

Abstract Effects of different types fertilizers; traditional NPK (1 g plant −1 ), 2, 4, 6 and 8 gm L moringa leaves extract (MLE), 10, 20, 40 60 mL aloe (AL) on vegetative growth, flowering Corms production chemical constituents Freesia refracta . were evaluated during two successive seasons (2020–2021 2021–2022). Treating plants with MLE caused increases in height, number if flowers by 35.2%, ...

Two separate factorial experiments were conducted to study the effects of explant sources, plant growth regulators, sucrose concentrations, and light conditions on in vitro cormlet formation of freesia (Freesia ×hybrida Bailey 'Argenta'). Interestingly, it was observed that the pupae had lower contamination levels compared to mother corms. Using 40% sodium hypochlorite solution for 40 min, cont...
