Abstract
The study included a breakdown of the costs of production per hectare for wheat and barley, which is divided into variable costs and fixed costs. In a sample of the private sector farms average total cost of the total hectares cultivated of barley and wheat around (942.34 dinars ,1066.52 dinars) during the season 2007 / 2008. While the overall average total cost per hectare cultivated barley and wheat in the sample of production projects overall productivity (Brjoj, Aldboat, Airaon) towards (1792.89 JD, JD 2019.17) on the relay during the season 2007 / 2008. While the cost of production per hectare on average, wheat and barley farms in the sample of the private sector before taking the value of the water in the account about (496.99, 546.66) dinars per hectare respectively, as the cost of production per hectare on average, wheat and barley in a sample of production projects overall productivity Before taking the value of the water in mind about (1135.8, 1245.75) dinars for wheat and barley crops, respectively. Efficiency of resource use groundwater for used in the cultivation of wheat and barley crops in the sample of agricultural production projects, and the overall productivity of a sample of the private sector farms where they put the price per cubic meter of water, where the study used measures of efficiency of expression on the economic evaluation of the element of water and which ones: the measure of net return of the unity of water per hectare as it hit the highest net return for wheat and barley crops in the sample of the private sector farms profitable amounted to about (0.42 JD / m 3 0.61 JD / m 3), respectively, while lower net return per unit of water. Was in a sample of agricultural production projects by (0.05 JD / m 3, 0.21 JD / m 3) for wheat and barley crops, respectively. The measure of productivity per cubic meter of water, where it became clear that the highest productivity per cubic meter of water in the sample private sectore farms (1.01 kg / m 3, 1.21 kg / m 3) of the barley and wheat, respectively. And less productive per cubic meter of water in the sample of agricultural production projects by (0.55 kg / m 3, 0.44 kg / m 3) for wheat and barley crops, respectively. The measure of the efficiency of the element of water has reached in the sample of private sector farms (1.27 JD 1.61 JD) for wheat and barley crops, respectively, while the agricultural production projects in the sample to around (0.78 JD, 1.12 JD) for wheat and barley crops, respectively The study found a set of recommendations including: follow the water policy based on the principle of exploitation of aquifers security both in terms of economic or technical, through setting a price for water used in agriculture. In addition to focusing on vertical agricultural expansion wheat and barley crops to increase productivity instead of horizontal expansion through soil conservation and the adoption of appropriate agricultural courses and the rationalization of irrigation and proper use of fertilizers, pesticides and improved seeds. The study recommends that attention to measuring the productivity of the element of water used to grow wheat and barley, compared with a productivity of water used to grow other crops, the study area to determine the priorities imposed by the efficiency of water use as well as the economic output of these crops, the study also recommends encouraging cultivation of wheat and barley crops in the sample private farms because of their relative importance in the higher productivity of the element of water and higher net returns per unit of water, lower costs of production per hectare and low consumption of water per hectare compared with the overall productivity of the sample production projects that did not achieve productive efficiency and economic requirements.
