IMPROVED COWPEA (Vigna unguiculata L. WALP.) RHIZOBIUM TOLERATE TO DROUGHT AND SALINITY CONDITIONS U

The aim of the study was to see how applying a mixture inoculation, as well as its resistance to salinity and a lack of moisture, affected the growth of cowpea plants and their absorption of N, P, and K nutrients. After planting and growing cowpea plants for 60 days, they were harvested and dried at 70°C for 48 hours, and their dry weight was taken, then milled, sifted, and digested, and N, P, and K were measured, and the roots of the plant were separated using a light water current, and the number of root nodules for each plant was counted. The findings revealed that:

1- In the cowpea plant, the mixed inoculation treatment (I7) increased dry weight, root nodule number, and nitrogen, phosphorus, and potassium concentrations.

2- Rising salinity levels reduced the rate of dry weight, average root nodule amount, nitrogen, phosphorus, and potassium concentration in cowpea plants, and reducing moisture conditions had the same effect.

3- The mixed inoculation increased cowpea plant tolerance to salinity and drought conditions, resulting in increased N, P, and K absorption, as well as improved root nodule formation and increased dry weight.
