Abstract
A field experiment was conducted to study the response of rice to application of
magnesium and sulphur in a typical laterite soil, using rice (variety Jyothi) continuously for two
seasons. Application of Mg had no influence either on the yield or uptake by the crop. Treatment
receiving the application of sulphurbiologically activated by inoculation with Thiobacillus sp. and
Aspergillus avomerii gave the maximum straw yield in both seasons of crop and thus a higher total
dry matter yield, indicating its influence on the vegetative growth of the crop. While lack of
influence of Mg application on the con tent of exchangeable Mg in soil was revealed, application of
biologically activated sulphur was found to ensure continued availability of S throughout crop
growth.
