ABSTRACT:

This research involved two experiments and was conducted in the experiment station of Faculty of Agriculture, Islamic University of Riau, Indonesia. This experiment was arranged with a randomly simple design with two factors. First, the effects of Pekanbaru city waste water and eggshell ash of palm oil on eggplant (Solanum melongena) and secondly the effects of Pekanbaru city waster water and Rhizobium inoculant on peanut (Arachis hypogaea) were investigated. The data analysis was performed with Duncan’s multiple range test with significant differences at p <0.05. The net assimilation rate and mean relative growth rate were used as indicators for the dry weight accumulation of plants. The combination of city waster water and rand eggshell ash of palm oil had an interacting effect on eggplant and peanut. An increase of net assimilation rate was followed by an increase in mean relative growth and a significant increase in dry matter weight was also observed. A combination of city waste water and eggshell ash of palm oil had a significant positive effect on plant growth in red yellow podzol land. Eggshell ash of palm oil can potentially balance excess iron and aluminum levels in soil impedes the absorption of essential minerals in red yellow podzol land. The combination of city waste water and eggshell ash of plam oil in red yellow podzol land increased the production of seed dry weight of peanut and fruit dry wet of eggplants.
