some experiments are conducted to study the
effect of soil erosion on crop yield. In such
experiments, the soil erosion is done artificially
at different levels in different experimental plots
and their effect is seen on the yield. A design in
minimal number of experimental units that
provides all possible pairwise treatment
comparisons called minimally connected design
has been developed. Minimally connected
designs are also useful for the experimental
situations, where the experimental units are
scarce. A catalogue of minimally connected
designs with some extra observations has been
prepared.
Another study is on Semi-Latin squares.
Semi-Latin squares are quite useful for the
experimental situations, where there are two
sources of heterogeneity in experimental units
that may influence the response variable and
have more than one unit in each row-column
intersection. A large number of such
experimental situations occur in consumer
tasting, glass house crops, residual effect
experiments, sugar beet trials, food industry,
organoleptic evaluation, etc. Semi-Latin
squares are also useful for obtaining fractional
factorial plans. A new method of construction
of Semi-Latin squares based on initial column
solution has been developed.Not Availabl
