Abstract

Wheat (Triticum aestivum L.) is the most important cereal crop in the world and is a major source of nourishment. It is one of the most important grain crops providing nearly 20% of the total world food requirement. In Bangladesh it is the second major cereal crop next to rice.

It contains carbohydrate (78.1%), Protein (14.7%), minerals (2.1%) and vitamins (Peterson, 1965). However, wheat suffers from about 26 seed Effect of Black Pointed Seed and Vermicompost on Leaf and Seed Infection of Wheat caused by Bipolaris sorokiniana
