Statistical and Economical Analysis of Date Tree Productivity In Iraq Of ( 1978 – 2008 ) Duration

Abstract

Statistical Analysis was achieved by using 1.Parametric Tests , One way ANOVA, and Two way ANOVA. 2. Non Parametric Tests by Kruskal – Wallis H Test to compare the mean productivity for seven kinds of dates which are Zahdi, Khistawi, Dary, Khadrawi, Sayer, Hillawi, and Others in Iraq of ( 1978 – 2008 ) duration , this means it was done thirty one block . The CRBD and CRD designs have the same efficient because the R.E. equal ( 100 % ) . The result indicated there were significant differences among the seven types of dates in their productivity at ( 0.01 ) level of significance . By the LSD test , the best was 1. Zahdi, Khistawi, and Others 2. Dary 3. Khadrawi, Sayer, and Hillawi . The productivity average was 50.81 , 46.1 , 42.21 , 38.17 and 28.8, 27.1. and 25.32 ( Kg/tree ) respectively . The average of all kinds was low in case of comparing it with the productivity average of date tree of Egypt . The important suggestion is to do our best to rise the productivity average by adoption of the useful Iraqi , Arabic , and World experiments and by adoption of Iraqi experts to farm the dates by intensive and extensive agriculture .
