Experimental Unit for Experiments on Plant

Abstract

Experimental unit used in any research on plant is the smallest group of plants or plant parts to which one application of a treatment is applied and can be measured to answer al lthe objectives of the experiment. According to the researches and information collected, the experimental units could be grouped as that for rice and field crop-experiments and that for trees. In the first case the researchers should consider the size, shape and the orientation of the experimental units which suitable to each specific crop. the detail, especially on teh agronomic trial was reported by the Statistical subdivision. For other trials, the size of the experimental unit both harvested area and border rows should be increased. For the experiment on tree, the experimental unit could be any part of the tree, single tree or several trees. In conclusion, the selection of the optimum experimental unit depend on many factors, e.g. type and size of the crops, treatment, influence of the external factor, including resourece used for the experiment.
