the sustainability of farming system (sofs) is considered to be an important principle in a broad concept of sustainable agriculture. variables affecting sofs include alternate crop farming (using nitrogen-fixing plants as alternate crops), utilizing farm animal manure, using plants and crop residues back into the soil system, and utilizing a variety of protective plowing schemes. overuse and p...

Excessive nitrate leaching from the U.S. Corn Belt has created serious water quality problems and contributed to the expansion of the hypoxic zone in the Gulf of Mexico. We evaluated the effect of implementing the late spring nitrate test (LSNT) for corn (Zea mays L.) grown within a 400-ha, tile-drained subbasin in central Iowa. Surface water discharge and NO3 concentrations from the treated su...

Corn-ethanol production is expanding rapidly with the adoption of improved technologies to increase energy efficiency and profitability in crop production, ethanol conversion, and coproduct use. Life cycle assessment can evaluate the impact of these changes on environmental performance metrics. To this end, we analyzed the life cycles of cornethanol systems accounting for the majority of U.S. c...

The use of mixtures of transgenic insecticidal seed and nontransgenic seed to provide an in-field refuge for susceptible insects in insect-resistance-management (IRM) plans has been considered for at least two decades. However, the U.S. Environmental Protection Agency has only recently authorized the practice. This commentary explores issues that regulators, industry, and other stakeholders sho...

Data collection used an interview with 60 respondents spread across three main corn-producing districts District, namely Woja Kilo District Pekat District. results showed that there was not too much difference b...

Corn, Zea mays L., is the cereal with the highest production rate around the world, with an estimated production that exceeded 1021 million tons in 2014 (1). Corn is also the staple food for over 900 million people located in sub-Saharan Africa, South Asia, and Latin America. Around 600 million people are corn dependent, including 120 million malnourished children (2). As an example, the averag...

Decline in Pesticide Use by Canadian Farmers Farmers in Ontario are spraying smaller amounts of pesticides on their crops than in the past. From 1983 to 1993, pesticide use dropped by a dramatic 28.3%, according to the Ontario Ministry of Agriculture, Food, and Rural Affairs (OMAFRA). By comparison, pesticide use in the United States fell 15% between 1982 and 1992. Under the Food Systems 2002 p...

INTRODUCTION Corn depredation by red·winged blackbirds (Agelaius phoeniceus) has been an agricultural problem in southwestern Ontario for many years. Large marsh areas along the shoreline of Lakes Erie and St. Clair provide ideal habitat for breeding and roosting. Concurrently, the vast monocultural field corn acreages in Kent and Essex Counties have over the years been the centers for blackbir...

Abstract Analysis of the value chain begins with raw materials and finishes a product that is ready for commercialization. The objective this article review to determine how analysis (value chain) used corn commodities in Indonesia. In chain, farmers, middlemen, inter-island traders, feed industry, breeders are considered stakeholders. After has undergone drying process been converted into feed...
