Effect of arbuscular mycorrhizal inoculation on nutrient uptake, growth and productivity of cowpea (Vigna unguiculata) varieties

Abstract

The objective of the present study is to find out the effect of Arbuscular mycorrhiza (AM) fungal inoculation on growth, productivity and nutrient uptake in two cowpea (Vigna unguiculata) varieties. The AM inoculated plants out performed than non-inoculated plants (control) in terms of growth, productivity parameters and nutrient uptake. AM fungal inoculation had a significant effect on productivity of cowpea attributed to growth, plant height, number of nodules, mycorrhizal dependency and number of flowers per plant.

Influence of Arbuscular Mycorrhizal Fungi (AMF) Inoculation on Growth and Mycorrhizal Dependency of (<i>Lens culinaris</i> L.) Varieties

“…number of leaves, leaf length, leaf surface area, stem girth and number of shoots respectively. The present study also confirm the findings that the inoculation of Rhizobium, rock phosphate and Vesicular Arbuscular Mycorrhizae (VAM) significantly increased the growth parameters and growth yield of Burgundy (Macroptilum bracteatum) under "P" deficient soil [17]. The endophytic fungi significantly increased shoot growth, chlorophyll contents, and plant biomass and leaf area of pepper plant as compared to fungal-free plants [16].…”

Responses of Cowpea Genotypes to Arbuscular Mycorrhiza

“…2). These results were for the most part in line with the results of preceding studies, which observed a high response of cowpea to AM fungal colonization and their positive contribution to growth improvement (Yaseen, Burni, & Hussain, 2011;Saidou, Singh, Abaidoo, Iwuafor, & Sanginga, 2012). Previously, Mosse (1986) classified cowpea into 'mycotrophic plants', which was greatly responsive to mycorrhizal colonization.…”

“…Some recently reports indicate that requirements for nutrients especially phosphorus might affect plant response to mycorrhizal infection (Mosse, 1986;Tawaraya, 2003;Wang, Zhao, & Bücking, 2016). Yaseen, Burni, & Hussain (2011) found that differences in growth response of several genotypes of cowpea to AM related to P supply.…”

“…Cowpea is responsive and very dependent on AM to meet its needs of nutrient (Yaseen, Burni, & Hussain, 2011). Some previous studies indicated that cowpea cultivars, even their genotypes had different responses to AM (Mercy, Shivashankar, & Bagyaraj, 1990;Saidou, Singh, Abaidoo, Iwuafor, & Sanginga, 2012).…”

Growth and nutrition of cowpea (Vigna unguiculata) under water deficit as influenced by microbial inoculation via seed coating

“…to the formation of a shorter mycorrhizal root system (Jacobsen, Smith, & Smith, 2002), relying on the fungal mycelium for nutrient uptake (Smith, 2000). In fact, there was a significant enhancement in shoot nutrient content (Table 2), particularly N and P, which has also been described in other studies with inoculated cowpea (Boby, Balakrishna, & Bagyaraj, 2008;Oruru et al, 2018;Sanginga, Lyasse, & Singh, 2000;Yaseen, Burni, & Hussain, 2011 and establishment increases the opportunity of seedlings to achieve a positive C and nutrient balance, which is crucial, especially under stress conditions (de Albuquerque & de Carvalho, 2003). Further studies are, therefore, needed to improve this limitation on the germination of cowpea seeds coated with AM fungi.…”
