This study was conducted to show the relationship between some soil properties and land productivity from wheat and barely crops. The study area located in Al-Muwafaqia - Waset Govornorate / central of Iraq. General soil data were collected from previous soil survey work done in 1992 ,and new soil samples from the same profile location were collected to determine some soil properties . The actual land productivity from Wheat and Barely crops were collected from the same selected sites . The results indicate some variations in land productivity for the selected crops and wheat productivity was higher than barely productions. Wheat productivity was ranged from 2000 to 2350 kg.ha-1 with mean of 2118.75 Kg.ha-1 , while barely productivity ranged from 2000 to 2350 kg.ha-1 with mean of 20187.5 kg.ha-1 . All soil properties show a positive and significant correlation with crops productivity except soil salinity which shows a negative correlation. Soil salinity considered as the most limiting factor for crops production as well as bad land management practices and the impact of the socioeconomic condition. [ABSTRACT FROM AUTHOR]

The study sample included 590 farmers in Wasit province, has been taking samples of soils that the first two levels of the samples 0-15 cm, and second 15-30 cm, from different agricultural people in the province, was the level of salinity of the soil analysis, in the laboratories of the Faculty of agricultural techniques / Musayyib, SPSS software to analyze the function and use the influence of the level of soil salinity on the productivity of wheat crop, and traversed by testing the function of class I and II, and turned out to be an inverse relationship which determine the level of critical soil salinity b 12.13 Desiminz / m, a level which even then the average revenue dunum with average costs, also identified the level of salinity of the soil, which then become the productivity of the crop is equal to zero when the function 18.163 ds m -1 . The study recommended that the Department of Agriculture is committed to non-introduction of land that soil salinity level higher than 12 ds m-1 within the agricultural plan for the province of Wasit, because that is a waste of economic resources. The study also recommended the need to draw a map of the levels of land salinity in general to determine the crop structure that is appropriate different levels of salinity, and recommended the encouragement of farmers who are their lands with high levels of soil salinity on other crops more tolerant to salinity, such as barley, alfalfa and clover, and others [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
