Abstract:
مما لا شك فيه ان للتجارب العاملية اهمية كبيرة في دراسة تاثيرات العوامل الرئيسية وتفاعلاتها، وتعد تجارب القطع الشريطية او المخططة Strip - plot Experiments او ما يسمى بتجارب القطاعات المنشقة split - Block Experiments احدى فروع او حالات التجارب العاملية حيث | There is no suspicion that the practical experiment have a great importance in studying the major factors and their activities ,and the Strip - Plot experiment or what it called Split - Block experiment considered as one of the practical experiments brunches where the steps are divided in the Analyzing Differentiation Diagram to three combinations , the first one is for the queues, the second one is for the colons, and the third one is for the experimental units which produced from crossing the queue with the colon with noticed that the horizontal and vertical strips should be in a vertical line with each other so there is no relation between their sizes. The levels of one factor normally distribute randomly over the strips of the queues and the levels of the other factor, and also randomly over the strips of the colons. By changing the randomization category (put the restrictions on the way of randomization) many kinds of designing the Strip - Plot appears. Hence, the aim of this research came to put the spot on these categories and put their mathematics sample, the statistical analyzing of each category, their usage’s, their characteristics, their features and their standard mistakes and to test the differences between the treatments average by using the method of Least Significant Differences. We cleared how to treat the problem of the one replication (because of loosing the mistakes) to test hypotheses by two methods. Finally we applying the kinds of the strip - plot designs practically standing on an experiment diagrams done in Abo Guraib Station yield that belong to Eebaa Center For Agricultural Researches. The program was written in ( Visual Basic ) language to make the statistic analysis for these experiments and applying practically the treatment of the repetition one.
