| According to the latest Land Use Planning of Guangxi Zhuang Autonomous Region, Guangxi is divided into five regions, which are eastern Guangxi, western Guangxi, southern Guangxi, northern Guangxi, and central Guangxi. Regional variation characteristics of grain production are introduced from two aspects of the decline of grain sowing area and the increase of grain output. According to the data in Guangxi Statistical Yearbook, comparative advantages of regional grain production in Guangxi Zhuang Autonomous Region are analyzed by the method of Comprehensive Comparative Dominance index. Result shows that eastern Guangxi and northern Guangxi have the maximum comprehensive dominance indices with the minimum increasing amount of dominance indices. Their... |

| On the basis of grey correlation analysis, 8 factors impacting grain production prominently as follows are selected to establish indices system: yield per unit（X1）, grain planting area（X2）, agricultural labor forces(X3), the total power of agricultural machinery (X4), using amount of fertilizer(X5), the damaged area of crops（X6）, effective irrigation area（X7）, and agricultural fixed assets investment（X8）. According to the relevant data of Inner Mongolia Statistical Yearbook from 1988 to 2008, we use the method of grey correlation analysis to analyze the factors impacting grain production in Inner Mongolia, quantify the correlation degree of the total grain output and all factors, and finally conclude the impacting capacity of all factors on grain... |

| According to the investigation results of grain production and demand status of administrative units at county level in Hubei Province in the years 2004-2007, status and trend of grain production and grain demand in Hubei Province are analyzed, so as to discuss the grain supply capacity of Hubei Province. Result shows that affected by the adjustment of agricultural structure and the transfer of rural labor, Hubei Province shows a significant decrease in grain production before the year 2002, and a gradual increase in both grain production scale and grain supply capacity after the year 2004. It is forecasted that in the year 2020, Hubei Province will provide 13100 thousand tons marketable grain to the state and will become a core province ensuring the grain... |

| Firstly, status of grain production in Henan Province is introduced. The rapid development of grain production has brought adequate food and clothing for Henan Province, has supported the development of industrial and agricultural production, has maintained the overall stability of the whole society, and has made great contribution to the national food security. Secondly, considering the small sample of research object, the uncertain poor information and the few restrictions on data distribution, the gray forecast is usually conducted by using time series data based on GM（1，1） Model. In order to ensure the high accuracy and the application in practical prediction, residual test is used. Thirdly, according to the grain productive data in Henan Province in... |

| A consorciação de milho e Urochloa ruziziensis apresenta potencial para os sistemas de produção agrícola, permitindo a produção de grãos e biomassa remanescente. O estudo tem como objetivo avaliar a produtividade e a viabilidade econômica das modalidades de consórcio de milho e U. ruziziensis na região noroeste do Paraná. O experimento foi conduzido em Maringá-PR, em delineamento inteiramente casualizado com cinco tratamentos (milho solteiro; U. ruziziensis solteira; milho com U. ruziziensis na entre linha; milho com U. ruziziensis na mesma linha; milho com U. ruziziensis em linhas intercaladas) e quatro repetições. Foi analisado o desenvolvimento inicial e produtividade de grãos do milho, e produção de biomassa de milho e U. ruziziensis. Os dados foram... |

| China's accession to the WTO poses great challenges to the Chinese agricultural sector, especially to the grain producers. Compared with major grain exporters in the world, most grain crops in China are high in production cost and weak in market competitiveness. This can be partly attributed to the fact that Chinese farmers are facing with poorer agricultural production infrastructures and inadequate public investment in agricultural research and extension, which leads to the lower efficiency in private inputs and thus higher private cost per unit of product. After China joining the WTO, protective and administrative measures conflicted with the URAA cannot be utilized as before. Alternative measures should be explored to provide help to farmers to... |

| According to the latest amended agricultural economic statistical data from 1996 to 2009 in Henan Statistical Yearbook-2010，by selecting and establishing the optimized grey model of logarithmic new developed coefficient, we conduct the empirical analysis and forecast research on the grain output and the relevant main economic indices in Henan Province from 2010 to 2015. The results show that the grain output of Henan Province in 2010 will reach 54.8969 million tons, and it will break through 60 million tons at 60.17 million tons in 2015. In years ahead, the grain output of Henan Province will develops to a new stage steadily, which guarantees the national grain supply and socio-economic sustainable development forcibly. |

| This study examines the sources of crop income growth in Indian agriculture over the 1980s and 1990s. Using a method developed by Minot (2003), the analysis decomposes crop income growth into the contribution of yield increases, area expansion, price increases, and diversification from low-value crops to higher-value crops. The results confirm that at the national level, technology (higher yield) was the main source of crop income growth during 1980s, while rising prices and diversification emerged as the dominant sources of growth in agriculture during 1990s. Diversification towards higher-value crops such as fruits and vegetables accounted for about 27% of crop income growth in the 1980s and 31% in the 1990s. However, these national averages hide... |
