Computation of vapour pressure deficit and crop transpiration via development of a web based computer module

Journal of Agrometeorology, 2021
The plant water or nutrient requirement under greenhouse conditions is mainly governed by crop transpiration in a linear relation to vapour pressure deficit (VPD), particularly in soilless production systems.
