Effects of Climatic and Agronomic Factors on Yield and Quality of Bread Wheat ( Triticum aestivum L .) Seed: A Review on Selected Factors

Abstract

The objective of this review work was to explore scientific facts on some of the key climatic and agronomic factors that affect production of quality bread wheat seed. Since it was impossible to cover all production factors once, selection of some of the factors was done. The selected factors for this review were rainfall and temperature among climatic factors while, seed rate and nitrogen fertilization were from agronomic factors. From the investigations of various workers, it could be concluded that rainfall, temperature, seed rate and nitrogen fertilization are some of the key factors that highly influence the state of the physiological processes in seeds and finally affect the yield and quality of seeds.
