Transgenic Crops describes the basics of genetic modifi cation for agricultural purposes and a brief history of the technology and the governing policies surrounding it. This publication offers a brief overview of the main agricultural crops that have been genetically modifi ed, the characteristics they express, and the market roles they play. Unintended consequences, economic considerations, a...

In recent years, because of the dangers of acid rain, the growth of main crops such as corn, rice, and wheat were inhibited, and cut back on production, so that the development of agriculture in various countries are hampered. In order to solve this situation, summarize the acid rain on main crops growth, biomass, germination rate, the influence of in order to improve the agricultural productio...

Regional planning should consider the impact of agricultural crops on housing value and leisure, as well as on the local environment. We designed an optimization model for allocating agricultural crops based on farmers profits as well as the impact on these three factors. Each crop creates a different landscape, as well as a different effect on shading and noise reduction. These in turn influen...

abstract in the present study, agricultural sector import was forecasted by using the econometric and the ann methods. import data from 1971 to 2004 and 2004-2009 was used for forecasting, network training and testing forecast accuracy, respectively. the results shown that feed-forward neural network has much less error and better performance than the arima and the var methods. on the basis of ...

The Green Revolution in Haryana has achieved much progress in agricultural productivity but at the cost of land and water degradation. Intensive agriculture during the Green Revolution period has brought continuous environmental degradation, particularly of soil, vegetation and water resources due to the use of high doses of fertilisers and pesticides. The adaptation of various modern agricultu...

A study on nutrient uptake by different legume crops was carried out at two locations–one at Bangladesh Agricultural University farm Mymensingh and another at Regional Agricultural Research Station of Bangladesh Agricultural Research Institute, Jamalpur. The objective was to find out the optimum concentrations of different nutrient elements and its uptake by legume crops in a Wheat-Legume-T. Am...

Drought is a complex and highly destructive natural phenomenon that affects portions of the United States almost every year, and severe water deficiencies can often become catastrophic for agricultural production. Evapotranspiration (ET) by crops is an important component in the agricultural water budget; thus, it is advantageous to include ET in agricultural drought monitoring. The main object...

The response of agriculture to changes in relative prices is an important factor in the success of structural adjustment programs in Africa. In this paper I estimate supply functions for total agricultural output, food crops and export crops in 14 African countries for the years 1975 to 1990. Food and export crops are substitutes in production in the short run. Total agricultural output respond...

BACKGROUND Pesticide use is widespread in agriculture. Several studies have shown that pesticides used in agricultural fields can contaminate the domestic environment and thus be an important source of pesticide exposure of populations residing nearby. Epidemiological studies that have examined the health effects of in utero pesticide exposure from residence near agricultural activities suggest...

The human population in Africa has undergone a rapid increase in the last decade and this, coupled with problems such as erratic rainfall, prolonged droughts and agricultural pest problems, has resulted in severe food insecurity. Advanced agricultural technologies, including the use of genetically modified organisms (GMOs), could play a role in enhancing agricultural productivity in Africa. How...
