INFLUENCE OF THE IRRIGATION ON WATER CONSUMPTION AND YIELD IN WINTER WHEAT AT ORADEA AND IN DIFFERENT REGIONS OF ROMANIA
Journal Title: Natural Resources and Sustainable Development - Year 2014, Vol 4, Issue 1
Abstract
The paper presents the results of research realized in the field of soil water balance in representative areas for irrigation in Romania. In April the highest optimum water daily consumption of winter wheat was registered in Plain Burnasului at Baneasa Giurgiu, 38m3 / ha and the lowest at Braila in Bărăganului Plain. In May the highest water consumption was registered at Valu Traian in Dobrogea, and the lowest daily water consumption was registered at Podu Iloaiei, Valu lui Traian and Mărculeşti. In June, the highest value of optimum water consumption was recorded at Oradea, and the lowest at Podul Iloaiei; in localities Oradea, Braila, Baneasa- Giurgiu and Caracal were recorded the maximum daily water consumption of winter wheat. Using irrigation in the conditions of maintaining of soil water reserve on watering depth between easily available water content and field capacity causes a substantial improvement in daily water consumption of winter wheat. Thus, under the moderately sub-humid zone of Crisurilor Plain during 19762014 average values of water consumption were higher than in unirrigation conditions with 19% -56%, pointing out that the maximum difference was registered in the last month vegetation, plant leaves maintaining the activity over a longer period of time.
