The aim of this study is to consider the energy consuming process and factors influencing three varieties rice production (Tarom, Khazar, Neda) under semi-mechanized and traditional systems, to investigate the energy consumption and economic analysis of rice in Mazandaran Province of Iran. Data used in this study were obtained from 63 farmers using a face to face questionnaire method, in farming year of 2011. The results showed that the highest total energy of labor requirements for Tarom variety rice production in Traditional and semi-mechanized systems, respectively, 2148.3 and 1547.1 MJ/ha was calculated. The Khazar and Neda varieties because of suitable genetic specifications have higher output energy in compared with Tarom local variety. Highest output energy with averages 183991.5 and 237701.70 Mj/ha of semi-mechanized system for Khazar and Neda varieties and also 161912.30 and 209173.50 Mj/ha for traditional system. The highest energy ratio of rice production was for Neda variety in traditional methods and semi-mechanized, respectively 7.03 and 7.95. The highest Energy Productivity (EP) of grain for both traditional and semi-mechanized cultivation systems was for Neda variety, that respectively, 0.20 and 0.22 kg/Mj. The highest Net energy gain was for Neda variety in traditional and semi mechanized systems, respectively, 179.42 and 207.82 GJ/ha that has been calculated. Highest income of rice production with 10834 $/ha (semi-mechanized system) and 9215 $/ha (traditional system) observed in Neda variety. Highest profit of rice production with 10039 $/ha (semimechanized system) and 8636 $/ha (traditional system) observed in Neda variety and so According to the results of this research and studying the energy and economic analysis, that the condition of the management of energy consumption in producing Neda varieties are more suitable and according to the need of country about producing rice. © Maxwell Scientific Organization, 2012.

In this study, the author has purposed that Shrinkage of potato sheets was tested and studied at the temperatures of 60, 70 and 80°C and air velocity (0.5- and 1 m/sec). In equal time intervals while drying, samples were photographed by the digital camera. Of taken photographs, body dimensions were obtained and analyzed. The results showed that drying of product was uniform at the temperature of 80°C and had more desirable and marketable temperature than the other temperatures. The air velocity at the testing area did not leave any effect on the shrinkage of the product. © Maxwell Scientific Organization, 2012. Source

The aim of this study is to consider the energy consuming process and factors influencing two varieties rice production (Tarom, fajr) under semi-mechanized and traditional systems, to investigate the energy consumption and economic analysis of rice in Mazandaran Province of Iran. Data used in this study were obtained from 76 farmers using a face to face questionnaire method, in farming year of 2011. The results showed that the highest total energy of labor requirements for Tarom variety rice production in Traditional and semi-mechanized systems, respectively, 2148.3 and 1547.1 MJ/ha was calculated. The fajr variety because of suitable genetic specifications has higher output energy in compared with Tarom local variety. Highest output energy with average 237701.70 MJ/ha of semi-mechanized system for fajr variety and also 209173.50 MJ/ha for traditional system. The highest energy ratio of rice production was for fajr variety in traditional methods and semi-mechanized, respectively 7.03 and 7.95. The highest Energy productivity (EP) of grain for both traditional and semi-mechanized cultivation systems was for fajr variety, that respectively, 0.20 and 0.22 kg/MJ. The highest Net energy gain was for fajr variety in traditional and semi mechanized systems, respectively, 179.42 and 207.82 GJ/ha that has been calculated. Highest income of rice production with 10834 $/ha (semi-mechanized system) and 9215 $/ha (traditional system) observed in fajr variety. Highest profit of rice production with 10039 $/ha (semi-mechanized system) and 8636 $/ha (traditional system) observed in fajr variety and so According to the results of this research and studying the energy and economic analysis, that the condition of the management of energy consumption in producing fajr varieties are more suitable and according to the need of country about producing rice. © Maxwell Scientific Organization, 2012.
