بررسی برهمکنش قارچ های میکوریزا و کود شیمیایی فسفری بر عملکرد، اجزای عملکرد و پروتئین دانه نخود (Cicer arietinum L.)

Application of bio-fertilizers, especially mycorrhiza as a complement or substituent for chemical fertilizers is very important in sustainable management of agro-ecosystems. In order to evaluate the effect of mycorrhizal fungi species and phosphorus chemical fertilizers on grain yield and protein of chickpea, a greenhouse factorial experiment based on completely randomized design (CRD) with four replications was conducted in ۲۰۱۴. Treatments were included three species of mycorrhizal fungi, Funneliformis mosseae, Rhizophagus intraradices, Claroideoglomus claroideum and non-inoculated control and three levels of phosphorus fertilizer from triple superphosphate (۰, ۵۰ and ۱۰۰ mg.kg-۱). Results showed, the highest plant height ۴۸.۸۳ cm, root colonization (۷۲ %) and chlorophyll index (SPAD) was achieved with Rh. Intraradices and ۵۰ mg.kg-۱. With increasing phosphorus from ۵۰ to ۱۰۰ mg.kg-۱, plants inoculated with mycorrhizal species showed a significant reduction in the number of seeds per plant and application of mycorrhiza with ۵۰ mg.kg-۱ showed the highest grain yield of chickpea. The application of ۱۰۰ mg.kg-۱ compared to ۵۰ mg.kg-۱ phosphorus with F. mosseae and Rh. Intraradices were reduced the protein percentage as ۱۳.۰۵ and ۱۲.۲۳, respectively. Therefore, application of bio fertilizer with chemical fertilizers may reduce consumption of chemical fertilizers without reduction in grain yield and protein that can achieve to sustainable and low-input agricultural systems.
