    Notizen: Abstract This paper studies the role of chemical fertilizers in sustaining the growth in foodgrain production in the major rice growing countries in Asia. The trends in fertilizer consumption are reviewed, the yield response and change in policies in the fertilizer sector and their impact on fertilizer prices are assessed and factors affecting fertilizer demand are analyzed. The implications of sustaining food security and the environment on fertilizer use are critically examined, future projections on food and fertilizer demand are made and areas of research needed to achieve the targets are suggested.

    Notizen: Abstract The immunogenicity of a sonicated extract (SE) and of outer membrane proteins (OMP) of Salmonella enteritidis was tested in birds of about 8 weeks of age. The dose, route of vaccination and the adjuvant used varied in different groups of birds. Two vaccine doses with or without adjuvant were given parenterally or orally 3 weeks apart. OMP vaccines gave significantly higher antibody titres than SE vaccines, as indicated by ELISA. The vaccines adjuvanted with oil produced higher antibody titres than those without any adjuvant. A dose of 1 mg of vaccine produced higher antibody titres than 0.5 mg of vaccine. Adjuvanted vaccine given subcutaneously elicited higher antibody responses than oral vaccines given without adjuvant. The birds were challenged with virulent S. enteritidis organisms at the end of the second week after a booster dose. None of the birds given 1 mg of OMP vaccine subcutaneously shed the organisms when tested by culturing cloacal swabs, although a few birds vaccinated with 0.5 mg of OMP vaccine did so. In general, adjuvanted OMP vaccines gave better protection than SE vaccines.
