Accurate crop performance monitoring and production estimation are critical for timely assessment of the food balance of several countries in the world. Since 2001, the Famine Early Warning Systems Network (FEWS NET) has been monitoring crop performance and relative production using satellite-derived data and simulation models in Africa, Central America, and Afghanistan where ground-based monit...

Wheat is widely grown in Iran as a staple food; therefore, the government there encourages farmers to produce wheat (a common agricultural enterprise) by increasing farm productivity and efficiency. The study compares the efficiency of wheat production for dryland (low input) and irrigated (high input) systems across Iranian provinces by using Data Envelopment Analysis (DEA). The average techni...

Conventional field cropping systems have been criticized as being unsustainable because they contribute to on-farm and off-farm environmental degradation, and are often economically uncertain. Methods to increase environmental and economic sustainability are needed. There is a critical need to develop management technologies to maximize yield and crop quality yet improve environmental impacts o...

cultivated area, yield and production trend of wheat (triticum aestivum l.), barley (hordeum vulgare l.), potato (solanum tuberosum l.), alfalfa (medicago sativa l.) and chickpea (cicer arietinum l.) as the main crops of kurdistan province were studied during 1983-2006 using time series analysis and the situation of future were predicted for 2006-2021 period. the results showed that the cultiva...

We investigated the recruitment and survival of the multimammate mouse, Mastomys natalensis, within irrigated rice and fallow field habitats at different time periods related to rice crop growth stages. Capture-Mark-Recapture data were collected for M. natalensis each month from June 2010 to May 2012, and both recruitment and survival were estimated in relation to land use (irrigated rice or fa...

The commodity markets have been bidding for acreage due to bio-fuels creating new markets for corn and soybeans. This demand-driven market may continue to provide marketing opportunities for 2008-2010. Currently, the major decision facing producers is determining the enterprise mix for 2008. This memo compares the Returns over Variable Costs for corn and peanuts and analyzes the break-even yiel...

Agriculture faces many challenges. In both public discourse and the scientific literature debates about future are increasing framed in terms of ‘alternative’ versus ‘conventional’ agriculture. this paper we critically examine framing, seek to understand how term conventional has been is being used. We argue that category agriculture little analytical purchase, its use part a strategy homogenis...

in this study, total factor productivity growth of iran’s pulses (including irrigated pea, dry pea, irrigated lentil, dry lentil, irrigated soybean, dry soybean and irrigated bean) during of farming years 1989-1990 though 2007-2008 had been analyzed, using nonparametric malmquist approach. so, amounts of inputs usages include seeds, fertilizers, dung, poison, herbicide, labor, water and acreage...

A survey was conducted to monitor the influence of city sewage irrigation on the heavy metal build up in soils around Bhopal. Concentration of the heavy metals in effluent was within safe limits. Diethylene triamine penta acetic acid extractable Pb, Cd, Ni, Co, Cr, Fe, Mn, Zn and Cu in the sewage irrigated surface soil ranged 3.5-6.8, 0.15-0.40, 2.56-5.58, 1.59-3.89, 0.45-0.55, 3.5-15.8, 3.6-8....
