<![CDATA[The study aims to determine the effect of organic fertilizers (chicken manure and burnt rice husks) on the percentage of NH4+ and NO3-, and to determine the correlation between total N with available N, as well as the correlation between the total percentage of available N with the yield of peanut plants (Arachis hypogaea L.). The study used a Randomized Block Design consisting of 3 treatment levels, namely: P0 = without organic fertilizer or control, P1 = 16 tons of organic chicken manure fertilizer ha-1, and P2 = 16 tons of organic burnt rice husk fertilizer ha-1. The results of this study indicate that only a small portion of the total N-in the soil is in the form of available N with the percentage of total available N only ranging from 0.028% - 0.063%. The total percentage of available N in chicken manure (0.053%) was higher than that of burnt rice husk fertilizer (0.048%) and the control (0.040%). There was a strong and very strong positive linear correlation between total N with available N, and there was a fairly strong positive linear correlation between the total percentage of available N with the number of pods and pod weight per plant.]]>
