RESEARCHES REGARDING THE OPPORTUNITY OF SOYBEAN IRRIGATION IN THE CRISURILOR PLANE PUBLISHEDCristian Domuţa, Cornel Domuţa, Maria Şandor, Alina Samuel
The paper is based on researches carried between 1976 and 2007 in Oradea, in the soil water balance plot. The opportunity of the soybean crop irrigation is sustained by researches regarding soil water regime and show that in unirrigated conditions, the water reserve dropped under the easily available water content in every year, thus irrigation was needed in order to ensure a proper water supply. Irrigation determined the improvement of the microclimate conditions and the increase of the consumption levels, and in the end obtaining high yield gains very significant statistically. Direct correlations between the water consumption and the yield and between the climate indicator and the yield are the arguments that sustain the opportunity for irrigation of the soybean crop in the Crisurilor Plane.
