THE INFLUENCE OF THE CULTIVAR AND IRRIGATION ON WATER USE EFFICIENCY IN POTATO FROM CRISURILOR PLAIN
Journal Title: Natural Resources and Sustainable Development - Year 2013, Vol 3, Issue 1
Abstract
Potato is a crop with important water requirement and during 2010-2012 at Agricultural Research and Development Station Oradea an experiment regarding the influence of five cultivars (Ostara, Moldoviţa, Desireé, Sante and Star) and two water regime (unirrigated and irrigated) on water use efficiency were studied. The optimum water provisionment on watering depth (0-75 cm) determined the use of the irrigation: 400 m3/ha in 2010, 3000 m3/ha in 2011 and 1900 m3/ha in 2012. The smallest values of the total water consumption were registered in the cultivar (Ostara) with the shortest vegetation period and the biggest values were registered in the cultivar (Star) with the longest vegetation period. The smallest yields were obtained in the cultivar with the shortest vegetation period (Ostara) and the biggest yields were obtained in the cultivar with the longest vegetation period (Star). The irrigation determined the yields gain between 15% an 21.9% in 2010, between 144% and 196% in 2011 and between 55% and 8% in 2012. The smallest values of the water use efficiency were registered in the droughty year 2011 and the biggest values were registered in the rainy year, 2010, both in unirrigated cultivars and irrigated cultivars. Water use efficiency of the potato cultivars increased in the irrigated variants; the biggest differences in comparison with unirrigated variants were registered in the droughty year, 2011; all the potato cultivars had the biggest values of the irrigation water use efficiency in rainy year 2010. The values of the irrigation water use efficiency increase together with the increase of the vegetation period duration. In average on the studied period, the smallest values of the irrigation water use efficiency (6.60 kg yield gain/m3) was registered in the cultivar with the shortest vegetation period (Ostara) and the biggest value (10.34 kg yield gain/m3) was registered in the cultivar with the longest vegetation period (Star).
