This Study aimed at investigating the effect of Morphometric characteristics of the wheat plant on its productivity morphometrological variables including the plant height, spike's length, spikes diameter, number and weight of grains for each spike, number of spikes per square meter, grain weight, and biological yield per square meter. Tow fields were selected in the study area of Mutah and AL- Mazar AL janoubi; which are located in a semi arid region in the southern part of Jordan. Elveation was included within variables as well. Thirty samples of wheat output were selected randomly in each field during the harvesting season of the period 2011/2012. Four statistical procedures including; simple correlation, stepwise regression, factor analysis, and principal components analysis were used to study the relationship between wheat grain yield and its morphometrological characteristics under semi arid conditions of the study area. Results showed that the number and weight of grain for each spike were the strongest variable affecting productivity. The second variable was the weight of 1000 grains for each square meter. Results suggest that a seeding quantity (8) kg /1000 m2 will yield a better harvest in the semi arid areas.
