In the meantime, foliar applications of aqueous methanol have been reported to increase yield, accelerate maturity, and reduce drought stress and irrigation requirements in C crops grown in arid environments, under elevated temperatures, and in direct sunlight. In addition, the methanol application had alleviating impacts on chickpea exposed drought stress condition. Positive effects of methanol foliar application on growth of plant have been confirmed in previous studies.Thus, the objectives of this study were to improve the physiological performance of sugar beet under different regimes of irrigation.In all treatments, methanol spray was applied times during stages of sugar beet development.The first spray was conducted in about leaves and the other two sprays were conducted with days interval.In the control plots, plants were sprayed with water.Water deficit stress was imposed from leaves stage to physiological maturity.In the laboratory, roots were weighted before providing pulp from them.Under drought stress condition due to increasing ABA in mesophyll, stomata are closed and eventually stomata conduction reduced in the leaf and dioxide carbons penetration is reduced for assimilation in the plant and finally cells turgid is decreased and decreasing turgid can confine roots growth. Photosynthesis, process occurred in chlorophyll containing tissues, provides the main materials for other metabolically vital processes. It has been documented that alterations in photosynthetic metabolism due to environmental changes or agricultural practices eventually will modify plant growth and productivity. LAI is related to the biologic and economic yields and increase in LAI causes higher yield. Sugar beet qualitative and quantitative characteristics are affected by methanol spraying.Based on the results, spraying of methanol up to had negative and poisonous effects on physiological characteristics.The results indicate increasing in the productive cost for crops than its basic value during the period. Regarding wheat, it was obvious that increasing the acres cost production is due to the increase in cost of agriculture lands rent, machines rent and labors fees.When using the real cost, it was obvious that increasing the cost is due to the increase in the cost of lands rent, chemical fertilizer and the other expenses.Regarding cotton, it was obvious that increasing the acres cost production is due to the cost of the lands rent, labors fees and fertilizer but when using the real cost, the increase of the cost is due to the increase in lands rent cost, chemical fertilizer and machines rent.These costs in return affect the profitability of acre.To identify the impact of applying this policy, records were used as analytical tools in analyzing and measuring the changes in the items of the acres cost of wheat and cotton in the light of applying those policies.The reason for doing this is to identify the best means by which the economical efficiency and the ideal usage of the economical resources of those crops can be achieved.The first is the base period which represents the period before applying the full liberalization policies and its variables are symbolized by which represents the period of applying those policies and its variables are symbolized by. This division is to identify the impact of applying those agricultural policies on the productive costs of acre items in the changes of the average production cost of acre of those crops between the two study periods by using the <a href="http://www.targetmol.com/compound/4-(4-Hydroxyphenyl)-2-butanone">buy
