Effects of Arbuscular Mycorrhiza Fungus Inoculation and Phosphorous and Nitrogen Fertilizations on Some Plant Growth Parameters and Nutrient Content of Soybean

Abstract

The aim of the agricultural production is to best supply the human requirements. This study aimed to investigate the effects of Glomus intraradices Schenk and Smith (Arbuscular Mycorrhiza Fungus = AMF) inoculation and Phosphorous (P) and Nitrogen (N) fertilizations on the some plant characteristics and nutrient content of soybean (Glycine max L. Amsoy-71). At the end of the study, while there were significant effects of inoculation on the plant height, the fresh and dry weights of shoots and phosphorous, potassium, calcium, zinc and copper contents in shoots, there was no significant effect on the nitrogen, magnesium, iron and manganese contents in shoots. Inoculation decreased the contents of magnesium and copper. Increasing doses of phosphorous and nitrogen applications significantly increased the plant height, the fresh and dry weight in shoots and the contents of nitrogen, phosphorous, iron, manganese and copper. © 2006 Asian Network for Scientific Information.
