Review on SYI (Sustainable Yield Index) of Wheat (Triticum aestivum L.)

Wheat is the major cereal and staple food crop of most of the northern regions of the country. Productivity of wheat in India is very low compared to other major producer countries of the world such as France (72542 Hg/ha), China (50505 Hg/ha) but sustainable yield index (0.832) is more compared to the China (0.800) and Russia (0.738) which indicate that there is no significant increment in the productivity of wheat and stagnation in the yield of wheat in India over a period of time. However, by identifying sub-optimal conditions an efficient scientific management can improve the wheat yield potential of the country to meet the future demand of food grain for increasing population.
