POSSIBILITIES FOR OBTAINING HIGH YIELDS FROM ROW CROPS IN WATER DEFICIT CONDITIONS: A CASE STUDY IN BULGARIA

The contemporary warming and drought tendencies are a serious reason for application of water saving and of high water use efficiency irrigation technologies. Since last years, wide-spaced furrow irrigation was tested on different soil types in Bulgaria ‐ vertisols, chromic luvisols and drained fluvi-calcaric fluvisols. The field experiments were conducted with maize (grain) and soybean. Both crops gave around 85% of the maximum yield when irrigated in every-other furrow with 50% of the optimum irrigation depth. The water use efficiency was increased with 71-79% at maize (grain) and 61% at soybean. In the paper, yields, moisture profiles, water use efficiency and yield losses are presented and analyzed. The every-other-furrow irrigation technology is recommended on clay-loamy soils as appropriate for increasing WUE, allowing application of less irrigation water and giving the chance for reducing the production costs.
