A crop is being tested in the lab to its loss due to transpiration. Given that initial weight of instrument is 100 kgs, and final mass of instrument is 150 kgs. The amount of water added during full growth of plant is 70 kgs. Find the loss due transpiration when the method used is phytometer method?

Correct Answer: 20 kgs
When phytometer method is used the formula for transpiration loss (T) = (M1 + M) – (M2) M1 = initial mass of instrument M = mass of water added during full growth of plant M2 = final mass of instrument Therefore (T) = (100 + 70) – 150 = 170 – 150 = 20 kgs.
