IMPROVING RHIZOBIUM INOCULATION IN-EFFICIENCY BY CO INFECTION, GROWTH AND N, P, K UPTAKE OF COWPEA (Vigna unguiculata L. WALP.) | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

 The aim of the analysis was to see how mixedinoculation affected plant development, Rhizobium bacteria efficiency in infecting plants, cowpea plant growth, yield, and nitrogen, phosphorus, and potassium uptake. The study was inspired by the concept of benefiting from the beneficial effects of microbial activity in the soil. The research included the use of a Rhizobium isolate isolated from cowpea root nodules (isolate R6).

In increasing dry weight, amount of root nodules, and nitrogen and potassium concentrations in cowpea plants, the mixed inoculation treatment with Rhizobium, Pseudomonas, and Mycorrhizae I7 outperformed single and double inoculation treatments with microorganisms.

2- To encourage plant growth and the development of root nodules, cowpeas must be inoculated with Rhizobium bacteria alone or in combination with Pseudomonas and Mycorrhizal bacteria or a combined inoculate.

3- In some of the studied parameters, such as dry weight, number of root nodules, nitrogen, and potassium, the mixed inoculation treatment (I7 + N3 + O1) did not differ significantly from the treatment (I7 + N2 + O1), resulting in a 25% reduction in nitrogen fertiliser recommendation, saving 10 kg N ha-1 and resulting in lower production costs and less environmental pollution.
