The colour of net in net house farming is 

  1. White

  2. Black

  3. Green

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Green shade nets allow many of the lights to pass through with minimal effect on photosynthesis, however the same is not true for all the colours. 
  • When the light passes through the shade nets, a fraction of light spectra gets reflected and that varies from the colour of light spectra.
  • In blue shade nets, the photosynthetic activity gets reduced and in black/grey shade nets, shade avoidance mechanism is observed as the plant's photosynthetic activity does not suffice it. 
  • Therefore, green shade nets are mostly preferred over other coloured nets.
So the correct option is 'Green'.
