Abstract
The study was carried out to assess the growth and yield parameters of okro and maize planted on crude oil remediated soil for sustainable crop production in Niger Delta, Nigeria. The study adopted experimental research design using Completely Randomized Block Design (CRBD) and was carried out in Ogulagha Grammar School, Demonstration Farm in Delta State, Nigeria. Four research questions guided the study. The sample for the study was 120 sack bags which represented 6 treatment groups replicated 5 times. A structured observation template was developed using information from the literature reviewed. The research instrument was subjected to face validation by three experts. Data were collected by the researcher with the help of one research assistant. The data collected were analyzed using mean to answer the research questions. The study found out that Adropogon gayanus and Sida-acuta as remedy to crude oil polluted soil can influence the growth and yield parameters of okra and maize in accordance with the volume of crude oil in the soil. It was recommended that Niger Delta Development Commission (NDDC) should encourage eco-friendly research and findings in their attempt to ameliorate the effects of crude oil spillage in Niger Delta, farmers should also adopt the cultivation of Andropogon-gayanus and Sida-acuta on crude oil polluted soil as a potential phytoremediation practice for sustainable agricultural production in Niger Delta, Nigeria.
