Sugarcane is one of the most important crops in India. Indian sugar industry is the second largest agro based industry, next only to the textiles. But, being a long durational crop, sugarcane is prone to the number of disease caused by pathogens viz. fungi, bacteria, viruses and phytoplasmas like organisms. Image processing techniques have been proved to be changing the scenario of agriculture ...
Introduction: Precision or “site-specific” management of ag production requires application of fertilizer, pesticides, water and other inputs on spatial scales much smaller than previously used. The concept is simple; by using accurate navigation and positioning to guide collection, sensors for crop yield, soil properties and other conditions can be used to develop maps or databases of crop res...
Global food production needs to be increased by 60-110% between 2005 and 2050 to meet growing food and feed demand. Intensification and/or expansion of agriculture are the two main options available to meet the growing crop demands. Land conversion to expand cultivated land increases GHG emissions and impacts biodiversity and ecosystem services. Closing yield gaps to attain potential yields may...
Nonpoint source (NPS) pollution is the major cause of impairment of US surface waters. The dominant source of NPS pollution is agricultural activity, and "traditional" pollutants nutrients, sediments, and pathogens are the main detrimental constituents. Erosion from cropland has been declining and is expected to decline further in the 1990s, but it is unclear how this will translate into change...
Abstract Subsistent/semi commercial farmers were very slow to adopt the new technology of maize cultivation, although introduction could be done by farmers, economies and compatible with farmer’s socio-culture. Generally, that was caused need high inputs (i.e. superior seed varieties, fertilizer, pesticides), other sides orientation cultivation subsistent/semi for food security, limited money b...
This article investigated 36 administrative villages in Heilongjiang Province, Jilin Province and Liaoning Province. The questionnaires ask about the issuance of local rural sanitation, solid waste, chemical fertilizers, pesticides, the use of plastic film and environmental protection activities. Statistics based on the questionnaires are as follows: Organic Waste is the major part of rural sol...
Food demand influences agricultural production. Modern agricultural practices have resulted in polluted soil, air, and water; eroded soil; dependence on imported oil; and loss of biodiversity. The goal of this research was to compare the environmental effect of a vegetarian and nonvegetarian diet in California in terms of agricultural production inputs, including pesticides and fertilizers, wat...
Unprecedented agricultural intensification and increased crop yield will be necessary to feed the burgeoning world population, whose global food demand is projected to double in the next 50 years. Although grain production has doubled in the past four decades, largely because of the widespread use of synthetic nitrogenous fertilizers, pesticides, and irrigation promoted by the "Green Revolution...
To reduce losses and increase agricultural yields, farmers, in addition to fertilizers, use pesticides achieve their objectives. With the absence of recognized commercial companies sale pesticides, growers buy these products local market. Most its farmers are not trained management so they often first introduce them. evaluate utilization products, a survey 50 producers indicates that more than ...
The conventional system of rice plantation has been applied in Malang, Indonesia. Standard chemical fertilizer and pesticide application were used this field. Soil samples rhizosphere showed the existence several entomopathogenic fungi including Penicillium sp, Aspergillus Trichoderma sp some unidentified fungi. diversity value also demonstrated a medium diversity. We conclude that an pesticide...
