The most promising potential of APV systems can be expected in arid regions where various synergistic effects may occur. Crop production may benefit from increased water savings by reduction in evapotranspiration and adverse effects of excessive radiation, while economic viability is increased and rural electrification is made possible (Majumdar and Pasqualetti …
1. Ozone–climate interactions and effects on solar ultraviolet radiation at the Earth''s surface. Measured concentrations of ozone in the upper stratosphere (altitude 35–45 km) show a statistically significant increase at mid-latitudes and the tropics since around 2000. 1 This increase is consistent with the predicted recovery of stratospheric …

The root system connects the plant with the soil, which is a key factor in determining the utilization of soil resources and plant growth potential. Solar radiation can change maize shoot and root growth and affect grain formation. In this study, the effects of different solar radiation conditions on root morphology of three maize cultivars XY335, …
The objectives of this study are to: (1) simulate and understand the relationships between crop GPP and absorbed photosynthetically active radiation (APAR) under varied illumination conditions using flux tower measurements and a two-leaf canopy model, and (2) develop a method to account for the effects of diffuse and direct solar …
The solar radiation for the Baoji and Weinan area showed an upward trend, while the solar radiation in Wugong was greatly reduced. The maturity date of winter wheat for the three locations was reduced by 2.3–14.9 days compared with the reference year for different climate change scenarios.
The updated solar radiation values are fed into a biophysical cropping simulation model to derive the effects of shading on crop productivity . The relationships between plant growth and AV plants …
Solar energy provides light required for seed germination, leaf expansion, growth of stem and shoot, flowering, fruiting and thermal conditions necessary for the physiological functions of the plant. Solar radiation plays an important role as regulator and controller of growth and development.

Productivity of kharif crops viz. rice, maize, jowar and bajra and rabi crops viz. wheat, and barley decreased with an increase in temperature or a decrease in solar radiation above normal.
3.2.. Generated daily solar radiationThe performance of the daily solar radiation generator that was used in this study was evaluated extensively by Garcia y Garcia and Hoogenboom (2005) for 17 locations in South Georgia, USA. Their study showed slight underestimations and overestimations for the lower and higher daily solar …
