EFFECT OF POTASSIUM APPLIED ON DIFFERENT NP BACKGROUND ON YIELD OF WINTER WHEAT IN PRELUVOSOIL CONDITIONS FROM WESTERN PART OF ROMANIA IN 2008-2010 PERIOD
Journal Title: Natural Resources and Sustainable Development - Year 2011, Vol 1, Issue 1
Abstract
Wheat requires significant amount of potassium for optimum growth and development. Adequate potassium fertilization improves the quality of the active plant due to improved efficiency of photosynthesis, increased resistance to same diseases and greater water use efficiency. In Romania, potassium fertilizers have been used much less that nitrogen and phosphorus fertilizers and therefore much less research work has been done concerning their placement and their effect on yield and quality production. In this paper will discuss the role potassium plays for yield and hectolitre mass in preluvosoil conditions from western part of Romania. The long term field experiment was carried out at the Agricultural and Development Research Station Oradea – Romania, begining with 1974 to ascertain the effect of potassium application on wheat in a crop rotation. Four different level of potassium (K) were applied on four NP backgrounds. The best performance of the crop parameters was recorded when 80 kg/ha was applied a different NP backgrounds
