Sulphur is increasingly being recognized as the fourth major plant nutrient after nitrogen, phosphorus and potassium. It is a key element in importance in the formation of proteins and ranks along with nitrogen and phosphorus. It also plays a key role in chlorophyll formation and oil synthesis. Sulphur requirement for optimal growth varies between 0.1 and 0.5% on dry weight basis of plants and it increases in the order gramineae sp. < leguminoceae < cruciferae. The efficiency of applied NPK fertilizers and the economics of their use are seriously affected under sulphur deficient conditions. Hence, higher crop yields may not be sustained. Field experiments on maize in different agro-climatic zones of the country showed that application of sulphur up to 45 kg ha-1 recorded higher growth, yield and yield attributes and also protein content with respect to quality parameters. However, S nutrient uptake by plants increases with the application of sulphur up to 60 kg ha-1 depending on the initial sulphur status of the soil. A panoramic view of sulphur nutrition in maize has been reviewed in this chapter.

Key words: Sulphur, Maize, Growth, Yield Attributes, Yield, Protein Content, Nutrient Uptake.
