Rice agricultural and economical importance increases progressively as it occupies a huge distant of farmed land (1.77 million feddan) that produces 6.579 million tons. This distance represents about 31% of the total summer agriculture cycle the year 2008. The national consumption of white rice is 4.5 million ton in 8 the year 2008. rice crop is one of the most important export crops. The total quantity that has been exported reached 37.128 ton earned 272.898 million dollars (19% of agriculture exports) as between 2004- 2008.
The problem of the study represented in not using modern techniques and not administering scientific knowledge and mechanical work and generalizing new seeds and types of rice of high productivity. Also using competent fertilizing means, using irrigation and draining modern ways and improving soil quality as well as developing ways of resistance represent many aspects of the problem. The study aims at interesting in biological agriculture as it has distinguished property or the so-called using modern technology packages that are available in experiences systems with their important role in keeping environment and saving water and producing high quality product that is free from pollution. This can be achieved by stabling agriculture information network related to internet.
The study aims at utilizing results of scientific research centers and universities by introducing those results or the so-called technology packages with their experienced systems in easy administered ways for the final user ”farmer”. These systems reached to cultivating new sorts of rice of high quality and high productivity need little water beside interesting in sorts cultivated in new lands.
The study uses the approaches of descriptive and quantitative analysis of statistical data and data of the subject and expressing economical relations among various variables by a algorithm ways. The study also uses different instruments; analytical & statistical; in measuring and assessment.
The study consists of five chapters the first one monitors previous studies interested in producing and consuming rice. The second chapter includes two sections the first concerns with the framework of experienced systems of agriculture and the second concerns with using the internet in agriculture guidance represented in faircon and radcon projects. The third chapter approaches the development of rice cultivated land, productivity all over the word and the most important export countries them on the local level in Egypt and the subject governorates after that between 2008- 2009. the fourth chapter approaches measuring functions of producing and costs in the study subject. The fifth chapter presents the most important kind of rice produced in Egypt with brief notes on the ways of planting rice in Egypt and selecting the study subject of users of experienced agriculture systems in Al Daqhelyia, Kafr Al Sheikh, and Al Buhaiyra governorates between 2008- 2009. the sixth and last chapter present obstacles and suggestions for using farcon and radcon projects in producing rice crop.
When studying Egyptian rice production we find it was 5.852 million tons between 1995- 2009. it was 4.788 million tons in 1995 and 7.240 million tons in 2008. with increase rate 51.7%. the total consumption of rice is 3.415 million ton between 1995- 2009. It was minimized in 1995 by 2.97 million tons and maximized in 2008 4.501 million ton by increase rate 51.5%. The individual consumption rate of rice is 44 kilograms a year between 1995- 2002. The lowest commotion rate was 37.8 kilo grams in 2001 and 59.8 kilograms a year in 2006. with increase rate 54.1%.
It was shown that most important governorates producing rice are Al Daqhelyia in the first rank in total production and mean land cultivated with rice (438.000 feddan – 27.8% of rice land in AR. E.). In the second rank kafr Al Sheikh governorate. Al Sharqyia in the third an Al Buhayra then AL Gharbyia in the fourth and fifth rank respectively.
The fourth chapter deals with measuring production functions based on creasing sector represented by rice cultivators utilizing faircon & radcom projects (The experienced system) and the comparative group in Al Daqhlyia, Kafr Al Sheikh and Al Buhayra the 2008- 2009 season. It was shown that cop- Doglass function the common function as it has many properties beside using the statistical approach called multiple staging curving.
The studied economic variables represented by feddan productivity by ton- feddan as a related variable. The used resources in production represented as independent variables which sorted by second quantity- kilogram/ feddan, mechanical work by hours- hour/ feddan, human resources per feddan- man/day/ feedan, nitrogen added to feddan per season by kilograms. The quantity of nitrogen shaped in active azot units, phosphor added to feddan zank, as fertilizers.
Measuring functions of rice production planted by experienced system in Al Daqhalyia the year 2002 showed that signal of mechanical work curve, phosphate and zank elements were positive, meaning that they correlated progressively with production quantity. 1% increase of those units would increase the crop of rice estimated by 0.120, 0.119 and 0.065% with the there variable shill the same. The human resources, phosphate quantity and zank must be increased.
The third chapter dealt with assessing cost functions of rice crops in experienced and comparative systems. Studying production costs in 2008 showed that azote fertilizer is the highest cost element (205.85- 2.14.78- 220.4) represenst 5.3%, 7.5.7 and 5.6% of the total cost per feddan. The human work is the second cost element (186.4- 233.6- 221.4) for the three governorates; Al Daqhelyia, Kafr Al Sheikh and Al Buhayra represent 4.8%, 6.2% and 5.63% respectively. The seeds quantity is the third and lowest cost element (Le 97.1, 90.4 and 98) represent 2.5%, 2.4% a 2.5% of the total cost per feddan in the same three governorates.
It was shown that civil estimation of costs in the experienced system was 4.27, 5.21, 4.44 and 4.2 tons for Al Daqhelyia, Kafr Al Sheikh, Al Buhayra and the total subject respectively in the season 2008. the same estimation for the comparative group was 4.27, 5.21, 4.4 and 4.2 tons respectively. The maximized profits in the experienced system was 6.3, 6.66, 6.66 and 4.4 ton respectively. As for season 2009 the civil cost estimation in the experienced system was 3.92, 4.2, 4.13 and 4.37 tons for the same three governorates and the total subjects and the comparative group 4.27, 5.21, 4.4 and 4.2 tons respectively. Thro profits were 4.99, 4.84, 5.44 and 5.96 respectively and the comparative group 6.31, 6.7, 6.7 and 4.4 tons.
In the fourth chapter it was shown that cursors of productivity and economic competence of rice crop were feddan productivity, cost of producing unit by Egyptian pound, net profit per feddan, the rate of profit by costs, the profit for each expensed pound, productivity of each cubic metre of water and the cursors were measured in both cases; using modern technologies in experienced systems and in ordinary ways. The mean production of feddan in 2008 by experienced system was 4.81, 433, 4.13 tons per feddan in Al Daqhelyia, Kafr Al Shikh and Al Buhayra respectively. The year 2009 was 4.08, 3.59, 4.13tons per feddan in the same governorates respectively. In the comparative system the mean production per feddan was 4.13, 3.9, 4.26 for the same governorates. Theses results confirm priority of experiences system.
Net profit per feddan in 2008 by experienced system was Le 3333.4, 2371.7 and 3129.3 per feddan in Al Daqhelyia, Kafr AL Sheikh and Al Buhayra respectively. In the comparative system it was 2309.1, 1535.6 and 2431.8 per feddan in the same three governorates. In the year 2009 it was Le 1766.1, 1490.9 and 1761.4 by the experienced system and Le 617.3, 818.1 and 465.2 by the comparative system confirming the priority of experienced system.
Net profit by costs in 2008 was 0.858, 0.575 and 0.797 for the same subjects in the experienced system and was 0.605, 0.399 and 0.645 per the same subject by the comparative system. In 2009 it was 0.45, 0.405 and 0.438 in the experienced system and it was 0.171, 0.222 and 0.177 for the same subject confirming the priority of experienced system. For the profit of each expensed pound in 2008 it was Le 1.22, 1.37 and 1.32 and 0.92, 0.58 and 0.47 in the comparative system. In 2009 it was 0.67, 0.59 and 0.67.
The third section in fourth chapter deals with problems and suggestions for the experienced and comparative systems in the subjects. It was shows that most important information needed by users (farmers or producers) in faircon and radcon projects is challenging pest sides and forming recommendations. Answers of users of agriculture information net- work and mobile revealed that going to agriculture guidance centres for utilizing in formations is the most important item followed by utilizing guiding newsletters. The most important problems faced by users of the experienced system network is the unavailability of computers, problems related to ensuring finance membership, network not accessible and telephone not available, As for suggestions they were ordered in importance as following, supporting finance membership, technical maintenance, saving technical suppliers, holding training cycles and making the net.
