Effect of Inoculant Rhizobium And Compost As Amelioration On Growth Of Peanut (Arachis hypogea) In Soil Post-Coal Mining

Abstract

This study aims to determine effect of inoculant Rhizobium and compost on growth and the number of root nodules on peanut in soil media ex-coal mining. This research used 2 treatments, which are Rhizobium (0, 10, 15, 20 and 25 g) and compost (0, 100 and 200 g) with 5 replied, respectively. Data obtained were analyzed with Analysis of Variances (ANOVA) followed by Duncan’s Multiple Range Test and Kruskall-Wallis (p=0.05). The results showed that the inoculant rhizobium and compost increased the growth of peanut and number of root nodules. The best growth of peanut (Arachis hypogaea) obtained by treatment of inoculant rhizobium 15 g and compost 100 g, and the most root nodules obtained by inoculant rhizobium 25 g and compost 200 g.
