I am farming onions and intend to solarize the nursery for my onions and I intend to use a black polythene paper. Would that be advantageous considering that a black paper absorbs heat hence raising temperatures better than transparent polythene papers as you have recommended?

Both clear and black plastic should work for solarization. Black was the norm until recently when clear plastic has gained favour. If you already have the black, just use that.
Thanks a lot, LMS
