Lattice designs

Combinatorial Design is a way of selection of sum of subsets from finite set which have specific characteristics. Incomplete Block Designs and Lattice Designs are examples of Combinatorial Designs. Incomplete Block Designs? usefullness is maximized when large number of treatments are to be tested. Lattice Designs can be used when it is difficult to find homogen data and large number of treatments occur. Lattice Designs can be considered that within each replication varieties may be thought of as forming a square array in which each row or incomplete block contains the same number of varieties. In a Randomized Block Design the pool of subjects is divided into blocks. In this study Lattice design is compared with Randomized block design. As a result of this comparison it is shown that Latis design is more efficient than Randomized block design
