The performance of a variety can not be measured with absolute precision. Uncontrollable variability influences the yield of each variety. One source of variability often found is the soil not being uniform throughout the test site (location). There are other factors that contribute to this variability. Some of the variables are uncontrollable due to economic and technical reasons. Statistical analysis is used to evaluate and make comparisons on what is being studied (yield), and at the same time measuring and evaluating the uncontrollable variables. Duncan's multiple range test was used to compare all variety yields to each other. Varieties that are followed by the same letter are not statistically different from one another at .05% level. This means if two yields are followed by different letters, then the higher yielding variety has a 95% chance of being superior to the lower yielding variety. A measurement of the uncontrollable variables is C.V. (Coefficient of Variation). As the C.V. increases, the amount of uncontrollable variables are increasing and influencing the test results.
