Tên sách: Efficient nutrient use in rice production in Vietnam achieved using inoculant biofertilisers

These proceedings provide a summary of the research outputs of work in Vietnam to assess the significance of a biofertiliser called BioGro. BioGro provides significant benefits for the growth and yield of rice. Apart from its technological content, this volume also contains five chapters emphasising economic or commercial assessments of the application of BioGro. Readers are left to draw their own conclusions about the significance of the BioGro. There is still room to debate; however, in the past decade the prices of N and P fertilisers have more than trebled, with few if any prospects that this trend can be reversed. As a consequence, it may be justifiable to expect major benefits from biofertilisers like BioGro for smallholder rice farmers in Vietnam and other developing countries in the immediate future rather than much later.

Inoculant biofertilisers are preparations that contain beneficial micro-organisms that are applied to crops with the aim of reducing or replacing more costly and environmentally damaging chemical fertilisers. Research has shown that rice yields in Vietnam can be maintained and even increased with reduced application rates of chemical fertiliser when treated with the biofertiliser BioGro. However, the benefits of reduced input costs and potential yield increases can only be achieved if there is adequate quality control of biofertiliser production. This manual provides a set of guidelines for the routine testing of biofertiliser quality. The methods chosen seek a balance between the use of modern technologies and the needs of developing countries with limited resources other than labour.
Tên sách: Quality Control of BioGro

Biofertilizer research for rice in Vietnam has focused on the isolation and selection of strains that can fix nitrogen, solubilize inorganic phosphates, stimulate plant growth, and breakdown soil organic matter. This paper assesses the consistent positive effect of BioGro on grain yield and agronomic parameters, including the rates and times for its application, the need for continued inoculation of crops grown in the same site, varietal differences, and nitrogen (N), phosphorus (P), and potassium (K) combinations on the effectiveness of BioGro. The commercial biofertilizer, BioGro, consists of four strains, one formerly considered as nitrogen fixing, Pseudomonas fluorescens, a soil yeast strain, Candida tropicalis is P-solubilizing, and two other bacilli, Bacillus amyloliquefaciens and Bacillus subtilis, potentially breaking down cellulose, protein, and starch. All four strains contribute to plant growth promoting rhizobacteria (PGPR) effect as shown by enhanced root growth. BioGro can be produced in local factories providing there is technical backup in the supply of starter culture and quality control of the final product.
