A greenhouse experiment was carried out to determine the S response and the plant S content of rice (Oryza sativa L.) cultivars OS-6 and IR-20 grown in sandy Apomu soil series under upland conditions. Sulphur application increased growth and dry matter yield. At low S rates OS-6 gave higher grain yield than IR-20. With high S rates, OS-6 responded more in straw production. The leaf S content was highest during early growth and decreased with plant age. At flower emergence, the blade of the Y-leaf appeared to be a suitable index for measuring the S status of the plant. The critical S level was estimated at 0.15%. The critical S levels in the grain and straw at harvest were estimated respectively at 0.12%, and 0.10%. The N/S ratios for the grain and straw at harvest appeared not to be a useful index for determining the critical S status of the plant. |
