IRRIGATION OF DIFFERENT CROPS ON THE BASIS OF DATE<br />
CONCERNING THE CLIMATE, CROP AND SOIL INCLUDED IN THE<br />
PROGNOSIS PROGRAM OF THE U.S.A. DEPARTMENT OF AGRICULTURE<br />
AND THE POSSIBILITIES OF ADAPTATION EXISTING IN ROMANIA<br />
The computer program of the USA Department of Agrioulture used in the<br />
irrigation prognosis of crops on the basis of dimate, soil and cropping conditions<br />
alre presen:ted, as well as the possibilities of its adapiJation to the Iconk:litions<br />
existing in Romania. The program consist in evaluation of water deficit in the soi!<br />
on the basis of elements composing a belance consisting of inputs (precipitations,<br />
irrigations) and outputs (evapotranspiration, percolation undeI" the root region of<br />
soil). The water balance is evaluated weekly on the basis of climate date (sun<br />
radiation, temperature, wind speed, precipitations), as well as on the basis of data<br />
concerning the growing stage of the crop, the amount of water applied by irrigation<br />
as well as the efficiency of irrigation waterapplied in the saH. The advantage<br />
of using such a program consist in the fact that on the ba8is of a minimum<br />
amount of data obtained from the eX'Perimental station (evapotranspiration of crops<br />
an short periods) and from the farm (precipitations, irrigations), the Irrigation<br />
System Center can make rapide, weekly evaluations an the irrigation starting<br />
moment as well as an the amaunt of water to be applied per plots and crops.<br />
The possibilities and measures to be applied in ardeI' of adaptation and improvement<br />
of this program of scientific management of crop irrigation as considering<br />
the conditions of our country; the program may be a real use in irrigation of<br />
potato crops
