Targeted research to identify the impact of current agricultural policy to cash crops (Potatoes. Cotton. and Rice) In Egypt. and this objective can be achieved through the Millennium instrumental following : (1) A study of the evolution of some of the variables associated with such cash crops. (2) Examine the Impact of current agricultural policy to each of the items of production costs and net returns per units each oi the three crops studied. (3) The study of the impact of current agricultural policy to Egypt's relative advantage in the production oi those crops under study. Results of study: (1) increasing the cultivated area oi each oi potatoes and rice during the study period. a growth rate of about 1.41%. 2.44%. the same arrangement. while cotton decreased rate of about 2.73%. (2) Increased productivity potato. cotton and rice during the study period. a growth rate oi about 1.18%. 0.03%. 2.72%. the same arrangement. (3) Increase the GDP oi potatoes due to the Increase in both the area and the productivity of the crop and the impact oi the change in the area is greater than that In the yield. While the increase In rice production is the impact of the change in yield per ieddan oi his biggest crop in the area. while declining cotton production since the rate oi decline in the area is greater than the rate of increase in productivity. (4) The increasing cost oi production for potatoes in the second period (1991-2004) is the full implementation of the current agricultural policy at 295.38% compared with the first period (1980 - 1990). this increase Is due to a change oi the value oi each lease ieddan. the value of the element of human labor. the value of a working animal. the value oi automation. value breeds value oi farmyard manure. the value oi chemical fertilizers. pesticides value. incidental expenses for the first period at 38.79%. 21 .23%. 0.18%. 10.59%. 51.46%. 5.90%. 18.34%. 4.48%. 10.39%. the same arrangement. (5) Increasing production costs for cotton at about 231.18% compared to the first period, this increase is due to a change oi the value oi each lease ieddan. the value oi the element of human labor. the value oi automation. the value oi seeds. the value oi farmyard manure. the value of chemical fertilizers. pesticides value. incidental expenses ior the first period at 98.17%. 25.40%, 10.38%. 2.39%. 2.40%. 8.84%. 2.27%. 5.02%. the same arrangement. (8) Increased production costs ior rice at about 243.33% compared to the iirst period. this increase is due to a change of the value of each lease ieddan. the value oi the element oi human labor. the value oi a working animal. the value of automation. value breeds value oi farmyard manure. the value of chemical iertilizers. pesticides value. incidental expenses for the iirst period at 125.88%. 20.15%. 0.88%. 24.41%. 3.55%. 0.80%. 7.13%. 8.42%. 5.74%. the same arrangement. (7) Increased net revenues each oi the potatoes. cotton and rice from the iirst period at 282.57%. 493.89%. 371.09%. the same arrangement. and due to the change oi productivity, price. cost and productivity. (8) The extent iactor comparative advantage for the production oi potatoes. cotton. rice during the first period at 0.57. 0.57. 0.38 the same arrangement. While in the second period of about 0.82. 0.92. 0.99 the same arrangement. This means that the current agricultural policy had led to deterioration in the comparative advantage in the production oi those crops. in spite oi Egypt. still have a comparative advantage in the production oi such labs because oi comparative advantage is still less than one.
