The effects of mycorrhizae inoculation on yield and nutrient uptake of canola following by maize

The aim of study was to determine the effect of canola residual by following second crop maize which is mycorrhiza-dependent upon growth, nutrient uptake and soil properties. The experiment was carried out in greenhouse and field conditions simultaneously for three years at the same place on a rotation at the Research Farm of the University of Çukurova, Faculty of Agriculture, Department of Soil Science and Plant Nutrition, Adana-Turkey. Canola, maize and horse bean were used as test plant and cocktail mycorrhiza (G. intradices, G. mossea, G. etinicatum, G. caledonium, G. intaradices, G. fasciculatum and Dr. Kindom species) was used as an inoculum. Under greenhouse conditions sterile and non-sterile soil was used. Under field conditions, the effect of cocktail mycorrhiza on canola and maize after canola growth were searched. For both of experiments, shoot dry weight, yield, root infection, P, K, Zn, Fe, Mn and Cu concentration, seed oil content, number of spore, dehydrogenase activity and CO2 production were determined.The results are shown that under pot and field experiment mycorrhiza inoculation have no significant effects on canola growth and nutrient uptake. Mycorrhiza inoculation significantly increased maize after canola plant growth and nutrient uptake compared to non-mycorrhizal treatments. Maize after canola rotation has a significant effect on growth, especially was more pronounced for mycorrhizal inoculation. Canola and horsebean mix cultivation has a better growth and nutrient uptake than single canola cultivation. Mycorrhiza inoculation increased microbial activity (CO2 production and dehydrogenase activity). Results are supporting our hypothesis that mycorrhiza inoculated maize after canola growth increased yield and nutrient concentration more than non inoculated treatments.
