The purpose of this study is to determine the effect of compounds residues generated by Vigna radiata cultivars Sriti and Mucuna pruriens on nitrification bacterial population.

The design used was factorial randomized block design with four replications, treatments used are two different soil types (Inseptisol (a1) and Vertisol (a2); Two Kinds of Produce legume residues (t), and two types of weed management (g). Results showed that Vigna radiata L. cultivars Sriti and Mucuna pruriens affect nitrifying bacterial populations, thus affecting the availability of nitrogen in the soil causes the N available N is not available to weeds that are living together. Causes of organic nitrogen content on weeds less than the organic nitrogen content in Vigna radiata L. cultivars Sriti and the content of Mucuna pruriens increases. Total population of nitrifying bacteria is influenced by soil type, causing the number of nitrifying bacterial populations between species and Inseptisol vertisol different.
