RESEARCH REGARDING THE INFLUENCE OF IRRIGATION ON WATER CONSUMPTION AND YIELD AT SOYBEAN CROP IN CONDITIONS FROM ORADEA AND IN DIFFERENT REGIONS OF ROMANIA
Journal Title: Natural Resources and Sustainable Development - Year 2014, Vol 4, Issue 1
Abstract
The researches were carried out in field of soil water balance from Agricultural Research and Development Station Oradea and in the other the same location from Romania. On irrigation depth of the soybean crop (Grumeza, 1989) has been taken to maintain the water reserve between easily available water content and field capacity. For this purpose soil samples were taken from 10 to 10 days, irrigation made it whenever the water reserve reached the minimum level. Monthly, the highest values of daily water consumption were registered at Podu Iloaiei (22 m3/ha/day) in April, Baneasa-Giurgiu in May (32 m3/ha/day) Marculesti in June (47 m3/ha day), Baneasa-Giurgiu in July (64 m3/ha/day) Marculesti (47 m3/ha/day) in August and Marculesti and Baneasa-Giurgiu (28 m3/ha/ day) in September. In descending order, the differences between yield of irrigated soybean and unirrigated were 167% at Valu lui Traian, 94% at Marculesti, 83% at Caracal, 80% in Braila, 67% in Baneasa-Giurgiu and 20% at Podu Iloaiei. In the conditions of irrigation in Oradea, the content of protein in grains of soybean crop was higher than protein content in the soybean grains obtained in condition of unirrigation.
