Arbuscular mycorrhizal fungi inoculation with organic matter and phosphorus supplementation enhance nutrient contents of Amaranthus tricolor L. and Basella alba L. by improving nutrients uptake

Abstract

Most of the vegetable crops retain an association with arbuscular mycorrhizal fungi (AMF) which can improve the growth, nutrition, water supply and tolerance to biotic and abiotic stresses of host plants. Therefore, the main objective of this study was to investigate whether the association of red amaranth (Amaranthus tricolor) and Indian spinach (Basella alba) with AMF, increase the shoot mineral nutrient contents and whether supplementation of organic matter and phosphorus enhance AMF association. The experiment was laid out in a factorial design considering three-factor viz. arbuscular mycorrhiza (AM), cowdung (CD) and phosphorus (P). There were five replications and total 40 treatment combinations. Results showed that in both vegetable maximum N, P, K, S, Mg, Fe, Mn, Cu and Zn and protein contents were observed due to the application of AMF and cowdung with phosphorus. The combined application of AMF with cowdung and phosphorus enhanced the association with plants and was more effective than only AMF application to enhance nutrient contents. Also, the uptake of almost all macro-and micronutrients increased due to the application of cowdung and phosphorus with arbuscular mycorrhiza.

Identification of soil microbial population under different land use

“…The soil microbial communities are the active component ecosystem. It had been revealed that microorganism varied in and between soil types with bacteria being the most numerous (Girvan et al 2003), It was reported that fungi in soil constituting a significant part of the soil biomass and served several important functions as decomposition of organic material, nutrient cycling, formation of soil aggregates and mycorrhizal symbiosis in soil (Kabir et al 2003, Tahjib-Ul-Arif et al 2018.…”
