Abstract:
Ninety papers were scanned in five international journals of repute i.e. Hortscience, 1984; Indian Journal of Agronomy, 1983; Canadian Journal of Plant Science, 1983; and Australian Journal of Experimental Agriculture and Animal Husbandry, 1984 to illustrate misuse of statistical techniques and poor data presentation in agricultural publications. Abuse of MC-tests was found in about 65 percent papers. Most glaring abuse of MC test was in factional experiments and quantitative related treatments. In 75 percent papers S.E. and C.V. was not given. Even presentation of data was without ANOVA table in the 50 percent papers. In factorial experiments, single degrees of freedom contrast method provides a more refined alternative to MC-tests. Whereas in quantitative data with related treatments, statistical methods like regression analysis and orthogonal polynomials have been found more useful compared to MC-tests.
