This investigation was carried out to evaluate some selected crops for their performance with irrigation water (production water) based on its salinity and the residual fragments of oil (hydrocarbons and heavy metals) and how the crops will be able to tolerate this situation. Six field crops were used in this experiment namely, cowpea (Vigna unguiculata), kenaf (Hibiscus cannabinus), pigeon pea (Cajanus cajan), salt bush (Atriplex lentiformis), henna (Lawsonia inermis) and samer (Acacia tortilis). Growth and development of these crops were evaluated based on their leaf characteristics, heights, fresh and dry weights, shoot and root lengths, and chlorophy contents. Results showed significant reduction in crops growth and development for all crops after the application of production water except Acacia. Seedlings of annual crops (cowpea, kenaf, and pigeon pea) died within six weeks after the application of production water. There was significant reduction in growth and development of Henna seedlings especially at bed A4. Seedlings of salt bush (Atriplex) and Samer (Acacia) showed significantly better growth and development compared to the other crops. The high salinity in production water which was greater than 15 dS/m at Bed A4 could be the reason of seedling senescence. The decrease in growth and development eason of the selected crops could be also attributed to the presence of fuel oil hydrocarbons in the production water.
