Sulphur Effect on Protein Components and Grain Yield of Wheat

Abstract

Based on the experiment in a plot of high soil fertility but low sulphur content with conventional fertilizer treatments(nitrogen,phosphate and potassium fertilizer),effect of sulphur on the protein quality and grain yield of the wheat cultivars with different protein contents were studied.A comparison was made between the grain protein content and grain yield with or without sulphur.The results indicated that the conventional fertilizer treatment with sulphur increased the nitrogen content in the wheat organs and kernel,and prolamin content and total protein content in kernel significantly.However,the wheat cultivars with different protein contents showed different reactions to sulphur fertilizer.The sulphur treatment significantly decreased the weight of 1000 grain kernels,but the decrease in grain yield did not reach a significant level.
