Confounded asymetrical factorial designs construction and analysis

Abstract

Experiments in agriculture require several types of designs. Situations in which treatments are combinations of factors with asymetrical factors are many. When the total number of treatment combinations is large, confounding is practised In order to get more precise estimates. Confounding is inextricable mixing up interaction effects with block effects. In the present study four different methods of construction of asymmetrical designs are attempted. In the first method polynomials In Galois field ore used for construction. These polynomials ore devised on the basis of two lemmas and following the line of Kichen end Srivastava (1959).
