Abstract:
ان فكرة القطع المنشقة كانت قد وجدت لتضيف الى مزايا ومواصفات التجارب العاملية فوائد تطبيقية تصب في تركيز وتحسين دقة واهمية دراسة تاثيرات العوامل والتفاعلات بينها كونها تحوي اكثر من مصدر للخطا العشوائي ونظرا لما نالته هذه الفكرة من توسع واضافات كثيرة في الج | The idea of split - plot had been found to add to the advantages of factorial experiments and specification of practical interest is in the focus and improving the accuracy and the importance of studying the effects of factors and interactions between them. they contain more than one source of random error because of the indiscriminate earned by the idea of expansion and additions in many theoretical and practical contribution to the diversity and evolution with approved design and since we have observed that the practical uses in our country , though many of it's but limited to the adoption of the idea of split - plot design or split - split only, and purpose of contributing to clarify and depend the understanding and importance in the practical aspects of these additions which has focused the aim of this research (thesis) to provide in depth analytical study of some of the designs , practiculary designs of split - plot and desins of split - Block and what could be concluded from the ideas of the designs that has practical benefits , especially in the agricultural field was taken as the theoretical aspects (models , plans , analysis ) to design of ,split - plots , split - plots systematic arrangement whole plots, split - plot in time & and analysis of Covariance and the design of split - Blokes and the designs of split - split plots & the design of combination between split - plots & split Block then the practical application had been don using The experiments in agricultural (including rice crop ,and crop of peas) Resulted modern & variety data for the year 2008 in the rice research station in Mashkhab in ALnajaf governorate in addition to data for chick pea crop obtained from the station of Rabiaa where the data were analyzed using (SAS - stetictical analysis system). the results of analysis showed that the variety Anbar 33 is the best compared to other varieties for rice crop , and the age 27 day is the best compared to other ages. The designs that have not been able to conducted, which is also not present previously in our country has been adopting the idea of simulation usin visual basic Program, as shown in the appendices ( program 1,2) done by the researcher deals the design of combination between the split _ plots and split Blocks compare it with _the design split _split plot - and the program no(2) that concerned designing split Blocks. The analysis Results for both designs performed to be used in agricultural experiment as it provides high accuracy.
