A factorial experiment with RCBD was conducted to test the developed manual planter-fertilizer and compare it with undeveloped manual planter-fertilizer and hand method for planting different crops: Okra, Cotton, Zeymays and Sunflower. Productivity, time of planting, broken seed percent and emergence percent, were studied in this experiment. The developed of cotton manual planter-fertilizer has been carried out by many modification for all tool parts .The old tool should be fixed on the place where seed should be plant by pressing it by hand to drill seed bed, but the developed tool works to push the seeds and fertilizers in the same time while it moves simply by hand on soil by tires. In the method we don't used high work to seeding and controlling the seeds depth easly in the soil. The results showed that tool productivity (hectare /hr) of the developed tool was increased by 263 % from the old tool and by 700 % from the manual method, the time of seeds planting for one hectare was reduced to 72 % hours by developed tool while it takes 80 % by old tool, broken seeds percent were reduced in both tools to zero and. Seed emergence % of the developed tool was increased by 7% from the manual method and by 4.4 % from the old tool. The results showed that significant differences for fertilizer or fertilizer and planter between old and development tool and manual method .The crops did not have a significant effect on seed emergency, ratio of broken seed, productivity, time.

The study included two experiments. The first one concerned on the effect of adding of soybean cake to the compost in the casing stage on the production while the second dealing with the effect of adding of calcium chloride in the casing stage on the storability of white mushroom. Results showed that adding sterilized soybean cake in their three concentrations (5%,7.5%, 10%) to the compost in the casing stage don't significantly increased the yield in the three harvesting stages, while the treatments with soybean cake in their three concentrations significantly decrease the yield of second and third flush yield compared with the control treatment. The yield for the two harvesting on the three concentrations was ranged 183.7 -40.8 g/box and 33.2-0.0 g/box respectively while it was in the control treatment 274.1 and 45.1 g/box respectively. Adding soybean cake in the three concentration decreased the total weight compared with the control treatment. The total yield in the adding treatment on their three concentrations range 894.5-249.1 g/box while it was 917.9 g/box in the control treatment. The adding of soybean cake in the three concentrations showed decrease in the biological efficiency of the fungus, it was ranged 62.8% -17.5 in the addition treatments on their three concentrations while it was in the control treatment 64.4%). Adding of calcium chloride in percentage 0.2% and 0.3% with the irrigation water after casing in the second experiment reduced percentage of yield loss to 0.07% and 0.06% respectively compared with the control treatment which had 0.17% yield loose after 7 days of storage. The spray treatment with 0.3% calcium chloride significantly increased the calcium content in fruit bodies tissue to 647.72 mg/kg compared with the control treatment which reached to 378.03.' Adding 0.3% calcium chloride significantly increased the dry matter content to 12.83%), this percent was significantly dropped to 10.99% when calcium chloride at 0.2% was used. Adding of 0.3% calcium chloride with irrigation water to the casing layer caused a significant increased in Ortho Dihydric Phenols "compound to 11.77g/l, while calcium at 072% and control treatment caused a significant decreased in Ortho Dihydric Phenols compound to 8.17 and 5.63g/l respectively.

The location and availability of modern life facilities make the city as an attractive to the people surrounding rural areas , and motivate them to apply patterns of urban life in their relations and targets. This is shown clearly through social activities and non-agricultural economic practices of the individuals of the society , which reflected on the different population characteristics. This research aimed to explain the step by step acceptance of socio — economic patterns urban life by the population of developing cities. This is done through studying some characteristics of these communities as the types of carrier , education level , income and size of family . This research depends on the approach of observation and explanation of the feneamena using the available primary and secondary data. The primary data is obtained from rural community of Al-Ameria , a village of Falluja city through personal interviews using a structured questionnaire. This area is chosen because of the location of Falluja between Baghdad and Ramadi (center of An--bar governorate) which helped developing this city , and hence developing and improving its agriculture. Results of research indicate the importance of carrier of the family head which considered the base of the socio-economic family conditions. Results recommended to improve rural community through setting and establishing different programs and policies to the community, such as education , other socio-economic activities and general services. There policies will rise the living standards of their communities. Continuous and trade off affecting are the two main characteristics to any community , and this will result what called the social phenomena. The Social Phenomena of the members of these communities will take an intermediate case between urban and rural , which called semi-rural. The semi-rural is distributed on a larfe extent in the urban areas, having a pattern of life differs from the urban life because of their socio-economic situation, and at the same time differs from the rural people in side of their rural life

Conditions of Iraq led to unbalance of several environmental balances. Treatment and correcting these unbalances become a critical matter especially when looking to get clear results to the short term. For decades ago, the two components of rural environment facing risks and challenges resulted because of several factors. The most important factors are the unbalance between the population size and the quantity of natural sources,, manufacturing, urbanization, wars, natural disasters, and diseases. Other important factors are pollution of natural environment , air, water, living and working area, soil which suffer double than other elements because of the effects of wars, fires, garbage, continuous destroying of the plant cover. Second type of pollution is the social environmental pollution, like disappears of principles and values, weakens of social relationships, break down of families, increasing the social problems like poverty and illiteracy. The problem of this research is the fact of Iraqi rural environment. This fact is so bad, its treatment lies on the shoulders of several specialists, especially the regional planners and social and environmental specialists. This is required setting of sustainable environmental policies.This research is aimed to indicate the role of regional planning in supporting environment, firstly, because of the characteristics of Iraqi rural environment. These characteristics are resulted from its location and the traditional and attitudes of the community. Secondly, through indicate the role of regional planning in supporting environment, firstly, because of the characteristics of Iraqi rural environment. These characteristics are resulted from its location and the traditional and attitudes of the community. Secondly, through studying the rural regions, their environmental performance and using all that in the modern model. To fulfill the aims, the research methodology based on analyzing the characteristics of the environment of the traditional rural regions using the published information's. Cross-sectional data were also used through a survey carried out in a rural community in Al-Khales Province.Main results of the research indicated that the traditional planning of rural regions is naturally and socially suitable with the environment, its look to be a part of the region environment and not imposed. Research recommended to return to the pattern of traditional planning which considered as a contieouse source to our modern region.

Principal component analysis is a widely-used method for dimensionality reduction of multivariate clustering data transformed into low dimensional data. It minimizes the sum of squared errors. The low dimensional structure of data can be effectively captured by PCA., transformed into new van ate s. Cultivar stability simply tested at multienvironment, GGE-Biplot depends on performance and stability means. Some cultivars could show low adaptation by PCA because there is no cultivar of a superior performance at all environments. Therefore, the PCA assists to select (based on stability and performance) a cultivar at multienvironments.PCA analysis could be used for selection depends on yield stability, forage crop biomass, cotton lint yield or certain disease resistance of different cultivars of a certain crop. Furthermore this method leads to discover indirect selection for other traits. The covariate effect pattern explained 81% of the GGE pattern in some trials, suggesting that the GE pattern for yield could be effectively explored by indirect selection for these traits and others as seed yield, early flowering and lodging resistance. The traits analyses that were affected by GE interaction using GGE-Biplot method were reviewed. The differences based on environment and cultivars variations. Performance means were estimated as cultivars performance at years or locations. It was explained how to conclude from the analysis to determine the optimal cultivar in performance and stability across several environments, to show specific or wide adaptation of genotypes .Along with this article,GGE-Biplot program was included for use.
