∗ Corresponding author: WU Quan, senior engineer, CAAE, mobile phone:+8613621043045 Abstract: Grain production is of great importance to any country, especially to China. It is very important for local and central governments to get accurate main crops acreage information in time. One noticeable problem is that the estimated accuracy for crops acreage in a certain year is not high, so that Remo...

C hronic hunger persists in most African countries even as crop production reaches peak levels on other continents (Johns Hopkins 2000). In sub-Saharan Africa, more than 600 million people live on small farms measuring no more than a few hectares each. Low productivity due to biotic and abiotic factors is responsible for food insufficiency and malnutrition. The rapid increase in population (nea...

Soybean is the most produced and consumed oil seed crop worldwide. In 2013, 226 million metric tons were produced in over 70 countries. Organically produced soybean represents less than 0.1% of total world production. In the USA, the certified organic soybean crop was grown on 53 thousand ha or 0.17% of the total soybean acreage in the USA (32 million ha) in 2011. A gradual increase in producti...

Corn harvested for silage is an important feed crop on most Pennsylvania farms, where cropland often is limited. The crop provides livestock producers with a high-yielding, relatively consistent source of forage and the animals with a highly digestible and palatable feed. Corn silage produces more energy per acre than any other crop grown in Pennsylvania. Corn silage serves as a high-energy for...

The development of small developing states has long been influenced by foreign aid. Apart from the macro benefits of bridging the savings and investment gap and building the foreign exchange gap, it is also said to stabilise output price, provide price certainty and affect output price positively. In this paper I examine these three aspects in detail with respect to the price subsidy that Fiji’...

The soybean economy experienced balanced sumption, such as modified-protein corn and cereal growth in both total demand and total supply since crops, and synthetic amino acids and urea supplethe early 1940's, but in recent years encountered ments, suggest possible long-range problems in the excess production. Since the soybean economy is utilization area. Production increases in' crops that eff...

NDVI obtained from satellite at the pixel over the area of crop cultivation would represent a specific temporal profile, which could be discriminated from that of other land use. In this study, the author attempted to estimate the acreage of winter wheat sown area using multitemporal NDVI obtained from NOAA-AVHRR data. The study site was selected in the Huang-Huai-Hai plain in China, where the ...
