Effect of arbuscular mycorrhizal inoculation on nutrient uptake, growth and productivity of cowpea (Vigna unguiculata) varieties
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.
Key words: Vesicular-arbuscular mycorrhizal (VAM), cowpea, nutrient uptake, mycorrhizal dependency (MD).
