Local food system potentials were studied in Washington County, Nebraska. As a departure from most studies of locally based systems, farmers were surveyed in addition to consumers for potential participation. Data about the current food system and opinions and preferences for local production, marketing, and purchasing of food were collected using selfadministered mail questionnaires. The respo...

Dairy farmers in many parts of the world rely on corn silage as a source of digestible fiber and readily fermentable energy for their cattle. In Florida, Georgia and many tropical countries, such farmers face several climatic challenges that can complicate corn silage production including temperatures that reduce the rate of photosynthesis (Crafts-Brandner and Salvucci, 2002) and reduction in p...

A conceptual model is developed to evaluate the effect of Bt corn on risk. Results highlight the importance of distinguishing between a farmer’s marginal and aggregate risk effects and demonstrate that the effect of Bt corn on risk depends crucially on the price paid for the technology. Empirical results show that, depending on the price, Bt corn can be marginally risk increasing or decreasing ...

In Indiana agricultural land is used mostly for corn and soybean harvesting. Rotated corn is a common practice, but in recent years, essentially due to the “ethanol boom” and increased profitability of corn production, many farmers have switched to continuous corn. Corn price increase affects the soybean-to-corn (STC) ratio, however, it is hypothesized that over time market effects will be felt...

A two-year field experiment was carried out to investigate the effects of nitrogen, composted manure, municipal waste compost, and weeds on yield and photosynthetic characteristics of corn. Experimental design was split split plot factorial with 3 replications. Main plots were weedy and weed-free, sub plots were nitrogen fertilizer levels [0 (N0) and 200 (N200) kg N ha -1 as urea], and sub sub ...

Several studies suggest that the $1.4 billion in government subsidies are encouraging the ethanol program without substantial benefits to the U.S. economy. Large ethanol industries and a few U.S. government agencies, such as the USDA, support the production of ethanol. Corn-farmers receive minimal profits. In the U.S. ethanol system, considerably more energy, including high-grade fossil fuel, i...

R. of China 071001 [email protected] China Agricultural University; CIRAD, Annual Cropping Systems, Montpellier, France Abstract: In order to analyze the impacts of Bt cotton on the farmers’ livelihood system, we interviewed 169 farmers and extension personnel in the main cotton production areas in He...

A simulation model of the temporal and spatial dynamics and population genetics of western corn rootworm, Diabrotica virgifera virgifera LeConte, was created to evaluate the use of block refuges and seed blends in the management of resistance to transgenic insecticidal corn (Zea mays L.). This Bt corn expresses one transgenic corn event, DAS-59122-7, that produces a binary insecticidal protein...

Abstract The researcher aims to determine the best planting time based on Smarter Approaches Reinvigorate Agriculture as an Industry (SARAI) and Crop Simulation Model (Planting Calendar), formulate site-specific nutrient management (SSNM). research study was conducted from May 2018 October 2021. There were twelve (12) adaptive calendar field trials in six (6) sites for Rice Corn. studies farmer...

the shortage of fresh water and growing competition for clear water makes less water available for agriculture production. the great chalange for the coming decades will be the task of increasing food  production with less water, particularly in countries  with limited water and land resources. therefore, increasing of irrigation efficienciy and decreasing of water losses are important factores...
