In order to evaluation of rootstocks effects on scion, six tratments including Troyer citange, Carrizo citrange, Citromelo, Gou Tou, C35-Citrange, Smooth Flat Seville with scion of page mandarin were evaluated in 5-year project based on randomized complete block design at Behshar Horticulture Research Station. In this study, vegetative traits including trunk diameter, tree height and crown width were measured during three sequentional years. The results of combined analysis of variance revealed significant mean square of years on all the traits of scion of page mandarin. Rootstocks had also significant effects on the page mandarin cultivar for all the traits studied at 0.01 probability level, which indicating significant genetic differences of six rootstocks for scion cultivar. Thrunk diameter of page mandarin ranged from 18.3 and 22.3cm on Smooth Flat Seville and Citromelo rootstocks, respectively and also this two rootstocks were classified at two different groups. For thrunk diameter of page mandarin, the rootstocks including Troyer citange, Carrizo citrange, Citromelo and C35-Citrange were classified the same statistical group. Rootstocks effects on crown width of page mandarin were classified in two statistical groups and Citromelo and Gou Tou rootstocks with 383.8 and 378.2cm of crown width were classified the same statistical group. Non significant interaction effects of year x rootstocks for all the traits indicating the same variation of the traits due to rootstocks in three sequentional years.

Chromium is an element that there is no report for its requirement in dairy cattle, but in two last decades is considered as a new research field in cattle nutrition and its roles innutrition and glucose metabolism in dairy cows were studied. This element is in sixth group in transition metals of periodic table and the form of is biologically active. The effects of chromium in the metabolism is mediated through insulin activity and by a compound named chromodulin. The results of researchs indicated that the use of this element in the diet of dairy cows results in positive effects in production, reproduction and metabolism especially in stress situations especially around parturition. Based on researches Chromium usually exerts its metabolic effects post absorption and it hasn’t any effect on the level of gastrointestinal tract.

Trade is the pickup and economy motor and everybody believe it as a biggest point to start the extension and pickup. In Islamic countries, trade is a solution of extension economy for these countries and it’s the different way.
On the other hand, trade development and extention economy at Islamic countries can be the deposit of human’s turnover.
On the other side these countries, can have the international trade if they have the highest level of human’s turnover and knowledge.
After that these countries should utilize the human turnover to have all the involves technology from involve stuff and they can collation the involve technology with the work place. they can change the rude stuff to the real stuff.
Then for recognition of extention structure. trade of countries in Islamic conclave, the goal of this search is resolution of erosion trade and human turnover at these countries and the effects is on the pickup economies.

The present paper investigates the role of culture building for enforcement of land applications laws in resistive economy. Within the last few years, due to the intensity of unilateral and inhumane sanctions imposed on Islamic Republic of Iran, to hinder Iran’s peaceful nuclear programs, a new term has been initiated and entered into our national economic literature , which was based on the contemporary status of our country. The agricultural sector of our country consisting of the three subcategories of agronomy, animal husbandry, fishery and forestation, is a major sector of our national economy. This sector does not receive an attention enough for its significant role in our security, society and economy. Iran, having the privilege of its four different seasons, has potentials for becoming an economic engine drive of a resistive economy that can serve as an alternate for an oil-based economy. All national economic sectors have experienced a negative growth since 2012 due to the impacts of the sanctions. While, the agricultural sector shows a growth of 6.3%. The study results reveal that agricultural investments can effectively result in economic development and growth and supply food chain. To develop this sector, it is required to restore and maintain agricultural lands while it is essential to prevent changing their applications. It is also important to know how to determine the application ratios of a natural environment and how to change such ratios as the time passes when defining and planning for comprehensive laws and for building a culture that promotes proper utilization of agricultural lands in the society. It is also important to expect the future changes when making long term plans and legislate effective laws and enforce such laws, and establish a proper interaction with the pertinent institutes and organizations in order to decrease or prevent crisis.

The study of dairy cattle nutrition in transition period has attracted many attention in recent years and the results of these studies shows that optimal transition from this period can result in health and longevity of dairy cattle in herd. Insulin resistance in the late pregnancy is an important compatibility to save glucose for uterus and mammary gland and continue to early stages after parturition and over a third of the pregnancy take place as a decrease in insulin sensitivity that is progressive and reversible. Insulin has many metabolic roles in maintaining nutrients in the body and glucose tolerance test is the usual method for measuring insulin resistance in the body. Factors such as pregnancy progress, fatness, type of cereal used in the ration, Synchronization of energy and ammonia supply to rumen microorganisms and ration supplying by chromium element are of effective ways in adjustment of insulin resistance.

After the glorious Islamic Revolution more than ever the political pressure, military and economic promotion of the predatory countries including America, Britain and the rest of his cronies against the great people of our country has been revolutionary and control a variety of sanctions and threats on their behalf and they have agents. This process continues until the nation under various pretexts Fact noble martyr to his knees and sinister goals that are plundering the country's resources gain. But the vigilance of the Muslim people with the leader Brave has dashed over tricky enemies. One of the new tricks of the enemies of the nation address on the achievements and production thatUsing its scientific capabilities can be achieved for the people of this country have been granted, that the divine powers and relies on scientists has made internal threat into an opportunity. The purpose of this paper is to produce domestic goods and its importance as well as practical solutions that can be relied upon to believe in reaching domestic product spent the bulk of sanctions that the interior can be achieved with the help and attention force and resistance to economically strengthen the economy of the country and resist bullies and their targets will be defused.
