        Water deficit is one of the most important difficulties, in which happes in dry zone and half dry zones.Water deficit, as the determinative factor, determinates the growing and extension of the plant cover inthese areas. Using the supper attractive, may reduce the production in the crops and control the plantcover in face of dry stress and water deficit. In this paper, the effect of supper attractive stockosorb onthe irrigation interval, number of irrigation time, content of utilizable water for the one growinginterval, efficiency of water use and seed practice in the surface unit and practice elements werestudied.In this paper four cares were studised, includig: instance care, full irrigation (in other word 4 to 5days) (T1), under irrigation in which is after the 75% outlet of moisture field capacity(T2), underirrigation by using the supper attractive (T3), and the last care is under irrigation with supper attractiveand solution propagation (T4). In irrigation level practises , irrigation for the instance was done when50% of field capacity was outlet. For irrigation deficit practices, 75% discharge of FC moisture wasthe base of irrigation deficit. More over this study showed that grain practise, number of grain range incorn, biological efficiency, stem diameter, and weight of thousand again in 5% surface weremeaningful. Moreover, biggest use of water is belongs to care of T4 and the lowest use belongs to careof T1. And this paper showed that in order to use this supper attractive polymer not only increasefunction of product efficiency but also increase the function of water using. پرونده مقاله

        Water scarcity as a limiting factor, vegetation growth and development for arid and semi-arid regions is considered as an inherent limitation for these climates. Due to heavy droughts in the last two decades in Lorestan province as well as excessive water consumption in the agricultural sector caused The issue of water efficiency in the agricultural sector in this province is important and needs many studies. Water resources in the world are limited And due to population growth And the demand for food and water for agricultural production will increase. On the other hand due to the virtual water trade Which is intended as a new solution Dealing with water scarcity is important, producing products that are produced with high water demand, It does not make sense in areas facing a water crisis. One of the ways to increase water use efficiency in agriculture is to increase the physical productivity of crops. For this, a study in the 2016-2017 crop year in the cities of Khorramabad, Durachegni and Kuhdasht have been studied to study the physical productivity of water and the volume of water used in canola cultivation. The results of this study showed that the average rate of physical water productivity in the management conditions of the operators covered by the project, For canola, it is equal to a minimum of 0.5 and a maximum of 0.67 kg / m 3 and an average of 0.613 kg / m 3 . The average volume of water consumed during growing season in the cities of Khorramabad, Durachegni And Kuhdasht are equal to 3588, 2971 and 3428 cubic meters per hectare, respectively. پرونده مقاله

        Water scarcity will face the world with a crisis of water resources management in the future. Water consumption in the agricultural, as the largest demand for water, has main roll in decision of many stakeholders in the economic, social and political fields. Nevertheless, research on its efficiency and effectiveness were done. On the other hand, due to droughts in the last two decades in Lorestan province of Iran and also the excessive consumption of water in agriculture, the issue of water efficiency in the agricultural is important and needs several studies. For this reason, a study was conducted to investigate the physical productivity of water and the volume of water used in sugar beet cultivation in the 2018-19 years in the city of Kuhdasht. The results of this study showed that the average rate of physical water productivity in the management conditions of the beneficiaries covered by the project, for sugar beet crop is equal to 6.06 kg per cubic meter and the volume of water consumed during the growing season is equal to 14841 cubic meters. At the end of the project and according to the obtained results, detailed recommendations were provided to the users in order to improve productivity and reduce the volume of water consumed. پرونده مقاله
