Neighbouring plant varieties problem in the damage resistant alpha design

This paper deals with repeatedly neighbouring plant varieties problem in Alpha design, especially in damage-resistant Alpha design introduced in [1]. Simulation study is employed for this purpose and damage-resistant Alpha design is compared to original Alpha design from the repeatedly neighbouring plant varieties point of view. Number of repeatedly neighbouring plant varieties is slightly but systematically higher in damage-resistant Alpha design than for original Alpha design, but there is considerable space to restrict damage-resistant Alpha design to reduce this number under satisfactory limit in many cases.
