Báo cáo nghiên cứu nông nghiệp " Biofertiliser inoculant technology for the growth of rice in Vietnam: Developing technical infrastructure for quality assurance and village production for farmers "

Biofertilisers are defined in this application as microbial inoculants, isolated from soil or the rhizosphere of plants, assisting the mobilisation of soil nutrients such as N and P and others in the plant rhizosphere and thus promoting the growth rate and yield of plants. Successful biofertilisers can contribute to increases in food production in a highly sustainable manner, with economic and environmental advantages. The extensive use of biofertilisers has the potential to better recycle the current nutrients contained in the soils and water of agricultural ecosystems and to reduce the negative impacts on ecosystems of chemical fertilisers | Project Title Code 1.4 Australian Personnel Australian Institution Biofertiliser inoculant technology for the growth of rice in Vietnam Developing technical infrastructure for quality assurance and village production for farmers Professor Ivan Kennedy University of Sydney Vietnam Institution Project Duration Hanoi Agri. University July 2000 - June 2002 Project Description Biofertilisers are defined in this application as microbial inoculants isolated from soil or the rhizosphere of plants assisting the mobilisation of soil nutrients such as N and P and others in the plant rhizosphere and thus promoting the growth rate and yield of plants.

The extensive use of biofertilisers has the potential to better recycle the current nutrients contained in the soils and water of agricultural ecosystems and to reduce the negative impacts on ecosystems of chemical fertilisers. This CARD project seeks to provide training and expertise related to quality assurance of mother culture strains of bacteria for biofertiliser inoculants used in paddy rice production in Vietnam. Similar quality assurance is required for biofertilisers produced by farming communities in Vietnamese villages used to inoculate rice seedlings. A range of techniques to identify and count inoculant bacteria have been developed in the SUNFix Centre located at the Universities of Sydney and Western Sydney see attached report ACIAR project CS 1996 217 . The project will simplify validate and further develop these procedures for routine application in Vietnam. Objectives a To establish simple microbiological and immunodiagnostic tests for providing quality assurance of mother culture strains of bacteria for biofertiliser inoculants used in paddy rice production in Vietnam. Similar quality assurance is required for biofertilisers produced in the field. In addition more .
