Abstract

Acacia nilotica is fast growing, drought resistant, multipurpose legume tree species occurring in semi-arid and arid zones of the world. AM fungi, which constitute a group of important soil microorganisms, are known to improve the plant growth through better uptake of nutrients. A total of eight sets of experiments were conducted to analyze maximum growth and nodulation in A. nilotica. The results of present investigation showed the maximum shoot, ischolar_main height, collar diameter and dry weight of ischolar_main nodules under soil treated with AM along with phosphate and nitrogenous fertilizers. It was minimum in the soil treated only with AM fungi. In another set of experiment, the maximum number of nodules/plant and its dry weight g/plant were found under soil treated with AM along with nitrogen followed by soil treated with AM along with phosphorus and nitrogen.

Abstract

Acacia nilotica is fast growing, drought resistant, multipurpose legume tree species occurring in semi-arid and arid zones of the world. AM fungi, which constitute a group of important soil microorganisms, are known to improve the plant growth through better uptake of nutrients. A total of eight sets of experiments were conducted to analyze maximum biomass accumulation, phosphorus and nitrogen content in Acacia nilotica. The results of present investigation showed the maximum biomass accumulation, phosphorus and nitrogen content were achieved under soil treated with AM along with phosphate and nitrogenous fertilizers. In another set of experiment, the increased biomass accumulation, phosphorus and nitrogen content in Acacia nilotica were found under soil treated with AM along with phosphate fertilizer followed by soil treated with AM along with nitrogen fertilizer. It was comparatively lowerin soil treated only with AM fungi.
