a field experiment was conducted to investigate the spatial distribution of weeds at the sari agricultural sciences and natural resources university in 2011. field was divided into 42 grids (1.5×1.5 feet) then all samples were taken from grids intersection points before corn planting, after harvesting and ear emergence stage. weed maps and semi variance analysis carried out using rw99 and gs+ s...

Over the past decade, donors have made a concerted effort to improve aid effectiveness. This intent was codified by the Development Assistance Committee of the Organisation for Economic Co-operation and Development in the Paris Declaration of 2005, under which development agencies agreed to manage their aid budgets on the basis of five principles, two of which included managing development fund...

Even though soil loss in the lowlands imposes not as much a restriction on land use and agricultural productivity as in erosion affected mountainous areas, the input of fine sediment into the rivers and streams is a concern due to water quality issues and substrate siltation. Drains, river banks and agricultural fields are the three main sources of fine sediment in lowland regions. For a succes...

Agricultural labor productivity is key for understanding aggregate cross-country income differences. One important proximate cause of low agricultural productivity is the low use of intermediate inputs, such as fertilizers, in developing countries. This paper argues that farmers in poor countries rationally choose to use fewer intermediate inputs because it limits their exposure to large uninsu...

The Conservation Effects Assessment Project was established to quantify water quality benefits of conservation practices supported by the U.S. Department of Agriculture (USDA). In 2004, watershed assessment studies were begun in fourteen agricultural watersheds with varying cropping systems, landscapes, climate, and water quality concerns. This paper reviews USDA Agricultural Research Service '...

trous 2007–2008 food price crisis, it was that it prompted governments and international donors to re-examine their priorities for agricultural development. They committed to invest in agriculture and food security in a manner that prioritizes small-scale producers (especially women), enhances the environment and contributes to the development of rural economies. While their promises to spend m...

The study examined the effects of government spending on the agricultural sector in Nigeria. The objectives were to: ascertain the effects of government expenditure (GEA), deposit money banks loan (DBA) and gross capital formation (GCF) on agricultural production output in Nigeria. The quasi-experimental research design was employed. The study employed time series data in its analysis. Data ado...

Agricultural drainage ditches in the Mississippi Alluvial Delta landscape vary from edge-of-field waterways to sizeable drainages. Ditch attributes vary with size, location and maintenance and may aid in mitigation of contaminants from agricultural fields. The goal of this study was to better understand how vegetative characteristics affect water quality in conveyance structures in the context ...

There is an unresolved debate about the potential effects of financial speculation on food prices and price volatility. Germany's largest financial institution and leading global investment bank recently decided to continue investing in agricultural commodities, stating that there is little empirical evidence to support the notion that the growth of agricultural-based financial products has cau...
