Growth Response of Calopogonium caeruleum and Centrosema pubescens Ground Cover Crops toward Inoculation of Bradyrhizobium, Aeromonas punctata, and Acaulospora tuberculata

Abstract

Planting of leguminous cover crops is a standard practise in preparing land for oil palm and rubber plantations. The synergism capability of Bradyrhizobium, Aeromonas punctata (phosphate solubilizing bacteria) and Acaulospora tuberculata (AM fungi) to increase growth of leguminous cover crops (Calopogonium caeruleum and Centrosema pubescens) was studied in a glass house experiment using polybag (10 x 10 cm) containing acid soil with low level nutrition of Ciomas, Bogor. Research results showed that Bradyrhizobium, A. punctata and A. tuberculata inoculation on C. caeruleum signifycantly enhanced plant height, and number of leaves. However, the treatment did not increase biomass and N, P, and K uptake of plant. Number of nodule were increase when the plant was inoculated with A. tuberculata alone or in combination with Bradyrhizobium and A. punctata. Centrosema pubescens gave good response when inoculated with A. tuberculata. However, dual inoculation of the two bacteria Bradyrhizobium and A. punctata with A. tuberculata signifycantly enhance plant height, plant biomass, N, P, and K plant uptake.

Growth Response of Mucuna bracteata with the Application of Local Micro Organisms (LMO) of Banana Weevil

“…Clearing oil palm land causes changes in the physical, chemical and biological conditions of the soil. Soil without vegetation is directly exposed to sunlight so it experiences erosion, reducing one of the impacts of planting legume cover crops (LCC) (Widiastuti and Suharyanto, 2007).…”
