Abstract:
This paper addresses the following issues: assessment of climate evolution trends and also updating water requirements in Fântânele Şagu Arad irrigation systems. The paper shows dynamic agri zoning after Berbecel in the parameters, positive temperature sum as annual multi-values and average annual rainfall amount, the area fits in moderate humid area, while the work indicates the MAI concept (Moisture Adequacy Index) by G. Hargreaves highlighting the gradually effect of water shortage on agricultural production depending on rainfall to provide 75% and reference evapotranspiration.In the second part of the work shown recalculation reveals water to the irrigation system, according to the methodology [7], ensuring climate deficit by E. Manole by assessing the net irrigation rate and consumption by evapotranspiration during the growing season.The paper ends with a case study for Fântânele-Sagu-Arad irrigation system, respectively irrigation water needs updating for irrigation from the base station of the arrangements with data obtained by calculations of the case study.
