The Effects of Applications of Fertigation and Mycorrhiza on Yield and Nutrient Uptake of Pepper Plant (Capsicum annum L.) under Field Conditions

Abstract

This study was conducted to investigate the effects of different fertilization frequency (fertigation in every irrigation, fertigation in every second irrigation, fertigation in every third irrigation) in fertilization application and inoculation of mycorrhizae on yield and nutrient uptake of pepper plant. The experiment was carried out under field conditions during two years with three replications at experimental area of Department of Soil Science and Plant Nutrition-Faculty of Agriculture-University of Çukurova. In the research, fertigation application was performed comparatively with conventional irrigation system. Pepper and Glomus caledonium were used as test plant and mycorrhiza species, respectively. In the study, yield and nitrogen (N), phosphorus (P), potassium (K), iron (Fe), zinc (Zn), manganese (Mn,) copper (Cu) concentration of pepper plant were determined. Results revealed that, while the highest yield (2809 kg da-1) was obtained from second every irrigation applied phosphorus and inoculated mycorrhizae in the first year, it was determined in every irrigation without phosphorus application and mycorrhizae inoculated with 2113 kg da-1 in the second year. Also, the application of fertilizer in every irrigation has been significantly increased P concentration of pepper plant, compared with the other treatments. In the study, generally, it was determined that the plants inoculated mycorrhizae have higher yield and nutrition uptake than non-inoculated plants.
