RESEARCH CONCERNING THE ECONOMIC EFFICIENCY OF IRRIGATION FOR THE SUGAR BEET CULTIVATED IN TRANSYLVANIAN PLAIN

摘要

The present study aims of to analyze the economic efficiency of the irrigation of the sugar beet crops cultivated with the aim of obtaining bioethanol. The analyzed crops were obtained within Vii?oara - Turda conditions, during 2008 – 2009, in a tri – factorial experiment (irrigation x fertilization x variety). Compared to 2008 and 2010, in 2009 a very significant (p 0.001) increase of the profit was recorded for the irrigated sugar beet crops. The Libero variety recorded the biggest profit for all three fertilization rankings that were practiced, followed by Clementina and Leila varieties. The irrigated x fertilized variants led to high efficiency in all studied sugar beet roots, within the conditions of the experimental field from Vii?oara - Turda, during 2008 – 2010.
