The results show that net radiation is dependent on net color and extent of shadowing. Our data show that solar radiation was lower in the plastic house (857 W m−2) in comparison to radiation in the open field (942 W m−2), as shown in Table 2.
Compared to control, solar radiation was significantly reduced by a shade of 50% compared to that of 40%. The greatest decrease of radiation intensity was recorded with black nets with 50% shade (515 W m−2).
