Abstract

This study was done to analyze the consumption and cost of electric energy and the economical results of bean crop ‘IAC-Carioca’ grown in Red Latosol (Oxisol) irrigated by central pivot, under irrigation management systems, TENS – tensiometry or TCA – climatological water balance based on “Class A” pan, under no-tillage (NT) or conventional tillage (CT) system, during 2003 and 2004. The study was done in the Demonstrative and Experimental Irrigation Area of FCAV/UNESP, Jaboticabal-SP. The electricity consumption was monitored and its cost was analyzed by tariff groups A and B. The price of Kwh of the tariff was obtained from São Paulo Company of Power and Light. The economical result was calculated by subtracting the income from the total production cost. Irrigation management by the use of TCA method showed higher electricity consumption and cost relative to the management carried out by TENS. The best economical return was found when the irrigation management was carried by the TCA under CT system.
