Behaviour of Miscanthus sinensis varieties in pedo-climatic conditions from North-East of Romania

摘要

The current research aimed to highlight the reaction of four ornamental varieties of Miscanthus sinensis Anderss. (,,Gracillimus”, ,,Silberfeder”, ,, Variegatus” and ,,Zebrinus”), in pedoclimatic conditions from North-East of Romania and foliar fertilization. Studies were carried out in conditions of experimental field of UASVM from Iasi, in the NW area of lasi City, Romania. Was studied the quality and fertility state of soil resources, determine the main quality features of hortic antrosol soil, fertility and quality diagnosis of soil resources, and also plants” reaction to foliar fertilization with Nutriplant Plus Universal. At all varieties was noticed a medium level of soil effective trophicity, higher values being at variants with a foliar fertilization of plants V2 (53 points) and to inferior limit at control variants V1 (48 points). Regarding plants”’ growing and development, all four varieties of Chinese silver grass had a positive reaction to foliar fertilization, exacerbating the decorative characteristics. The recorded results enlightened a good adaptability of the studied varieties at soil and climate conditions from the studied area and a favourable reaction for foliar fertilization.
