STUDIES ON THE PHYSIOLOGY AND PRODUCTION OF WHEAT

Abstract

Wheat (Triticum aestivum L.) is the leading food crop in the world fanning and the most important cereal crop grown in Egypt. Increasing wheat productivity under Egyptian conditions is one of the main targets of the agronomists.

The yield of wheat IS a function of many factors among which preceding crops, seeding rate and nitrogen fertilization are of great importance. As wheat comes after summer field crops in the rotation, the species of preceding crops play a dominant role in the production of wheat plant. Moreover, the amount of seeding rate and fertilizers are among factors of prime importance influencing the yield of wheat. Nitrogen is the plant nutrient most universally needed to meat the fertilizer requirement for the high crop yields obtained in Egypt.

Therefore, the objectives of this investigation were to study the effect of the preceding crop, seeding rate and nitrogen level on the growth, yield and yield components of wheat cv.; Giza 163 (Triticum aestivum L.).
