“…about 4-5 times less than the minimum light intensity required for the normal photosynthesis. Similar results recorded in present investigation are in agreement with the finding of Kulkarni et al, (2015) in Mango, Peri et al, (2009), Wang Tian et al, (2008) in Cucumis sativus and Juntamanee et al, (2013) in mango.…”

The research project entitled “Study of Photosynthetic Light Intensity Responsive Curve of Mango Cv. Alphonso under Man-Made Light Source. All physiological process required optimum light conditions. The amount of photosynthesis efficiency depends upon the light intensity levels. Treatment details were 100 pfd, 250 pfd, 500 pfd, 750 pfd, 1000 pfd, 1250 pfd, 1500 pfd, 1750 pfd and 2000 pfd with four replications were made. The obtained results were the saturation point in the photosynthetic light intensity responsive curve of mango Cv. Alphonso was in between 750 - 1000 pfd. The maximum rate of physiological activities were higher in this saturation point (i.e. photosynthesis, transpiration and stomatal conductance rate).

“…The highest rate of photosynthesis occurred near the light saturation point, which resulted in the highest stomatal conductance rate. Similar results were obtained by Wang Tian et al, (2008) in Cucumis sativus and Juntamanee et al, (2013) in mango.…”

“…In a study, a plastic roof was use to provide shading to mango leading to a reduction in the photosynthetic photon flux density (PPFD) by about 700 µmol m -2 s -1 . This leads to an increase in the Anet of the plant [21]. The maximum photosynthesis of M. indica obtained in this study is 6.62±0.12 for sun leaves.…”

Light is an important environmental factor that have an influence on a plants photosynthesis and production of secondary metabolites like phenolic compounds and flavonoid. Mangifera indica from the family Anacardiaceae is known to have bioactivity due to its phenolic and flavonoid contents. The objective of the study is to determine the influence of light on the photosynthesis and phenolic contents of M. indica. Photosynthesis of the plant was measured using a portable photosynthesis system referred to as LICOR-6400. Photosynthetic pigments as well as phenolic and flavonoid contents were quantified using a UV-VIS spectrophotometer. The outcome derived from the study shows that sun exposed leaves of the studied plant were having the maximum photosynthesis, saturation and compensation points (P < 0.05). Moreover, sun exposed leaves were having higher carotenoid, phenolic and flavonoid contents but lower chlorophyll contents. This leads to a conclusion that sun leaves of M. indica contribute the highest photosynthesis and phenolic contents to the plant.

“…Beside these drawbacks, this sheltering by the PV panels could also help reduce the infestation of fungal diseases after persistent rainfall. The severity of anthracnose, one of the major post-harvest diseases in mangos grown in humid regions that often occurs after rainy seasons (Arauz 2000), has been found to decrease under a plastic roofing (Jutamanee et al 2013). Comparable results have been observed by Du et al (2015), who also found the severity of several fungal diseases to be reduced in sheltered grapevines in rainy regions of China.…”

“…The occurrence of sunscald in tomatoes (El-Gizawy et al 1993) and sweet peppers (Rylski and Spigelman 1986) grown in Egypt and Israel (Negev desert), respectively, was found to be reduced under shaded compared to full-sun conditions, showing that shading most notably acts as protection from excessive solar radiation and high temperatures in the studied regions. For fruit trees such as kiwi and mango, moderate shade has been found to increase fruit quality (Jutamanee et al 2013;Wang et al 2007) and partly even yields (Allan and Carlson 2003). These findings have been associated with enhanced protection against adverse climatic conditions such as high temperatures and excessive rainfall.…”

The expansion of renewable energies aims at meeting the global energy demand while replacing fossil fuels. However, it requires large areas of land. At the same time, food security is threatened by the impacts of climate change and a growing world population. This has led to increasing competition for limited land resources. In this context, the combination of photovoltaics and plant productionoften referred to as agrophotovoltaic (APV) or agrivoltaic systemshas been suggested as an opportunity for the synergistic combination of renewable energy and food production. Although this technology has already been applied in various commercial projects, its practicability and impact on crop production have hardly been investigated. In this review, we give a short summary of the current state of the art and prospective opportunities for the application of APV systems. In addition, we discuss microclimatic alterations and the resulting impacts of APV on crop production. Our main findings are that (1) crop cultivation underneath APV can lead to declining crop yields as solar radiation is expected to be reduced by about one third underneath the panels. However, microclimatic heterogeneities and their impact on crop yields are missing reference and thus, remain uncertain. (2) Through combined energy and crop production, APV can increase land productivity by up to 70%. (3) Given the impacts of climate change and conditions in arid climates, potential benefits are likely for crop production through additional shading and observed improvements of water productivity. (4) In addition, APV enhances the economic value of farming and can contribute to decentralized, off-grid electrification in developing and rural areas, thus further improving agricultural productivity. As such, APV can be a valuable technical approach for more sustainable agriculture, helping to meet current and prospective needs of energy and food production and simultaneously sparing land resources.
