Abstract
In this paper has been reported the result which the evaporating power of atmosphere close to the ground in the growing space of crops was measured with the new filter's atmometer by Daigo which was previously reported.
Measurement of the evaporating power was carried out in the following 6 places: open place, glass house, paddy field, corn field, maize field. and bean field.
Process of change and difference of amount of relative evaporation: (amount of evaporation in every place/amount of evaporation in open place×100) based upon the growth and difference of sort of crops in every place is as shown in Fig. 1. On and after the last decade of July the amount of relative evaporations were maintained constantly as follows: paddy field 20%, glass house 40%, bean field 70%, corn field 75%, maize field 80%.
Relations between amount of evaporation in open place and amount of relative evaporation in every place are shown in Fig. 2.
