The Effect of Various Organic Wastes on the Development of Kidney Bean (Phaseolus vulgaris L. var. Pinto) and Arbuscular Mycorrhizal Fungi

Abstract

In the study, it was aimed to determine the effect of different organic wastes [grape pomace (Gp), hazelnut husk (Hh), and hazelnut groats (Hg)] on the development of kidney beans (Phaseolus vulgaris L. var. Pinto) and Arbuscular Mycorrhizal Fungi (AMF) [Rhizophagus irregularis (Ri), Gigaspora margarita (Gm) and Commercial AMF (ERS)]. The plants were grown in climate chamber conditions in the growing medium prepared by mixing 3% of organic wastes into the soil. At the end of the experiment, AMF root colonization, mycorrhizal dependence, spore density in the soil, total phosphorus (P) amount in the plant were determined and plant growth parameters (shoot diameter, shoot length, root length, total plant fresh and dry weight) were evaluated. According to the data obtained, Gp had no effect on AMF root colonization and soil spore density, but increased mycorrhizal dependence and P content. While root colonization of Hg, Ri and Gm increased mycorrhizal dependence and spore density in the soil, Hh had a positive effect on Gm's mycorrhizal dependence and spore density in the soil. While the application of Hg and ERS together led to an increase in some development parameters in the plant, the interaction of all organic wastes with AMF species increased the total amount of phosphorus. As a result, it is seen that these agricultural wastes are promising in terms of both plant growth and promoting beneficial microorganism population in the soil. In this context, it is thought that recycling of agricultural wastes will be beneficial in terms of ensuring the sustainability of agricultural production as well as protecting soil and environmental health.
