On the basis of adequate understanding the significance of virtual crops research, according to the research state and characteristics of virtual crops’ typical modeling methods at home and abroad, a new modeling thoughtway of virtual crops system was put forward based on Agent technology. This method established crops self-learning system based on neural network. It is helpful to understand cr...

The environmental, social and economic consequences of the use of fossil fuels has led to the search for new energy resources, such as energy crops which are expected to contribute in alleviating energy problem while they can lead to the diversification of the agricultural production. This research work investigates the acceptance of energy crops in the Larissa regional unit using questionnaire...

The share of single species was expressed for the weed flora in the Podravina region, North Croatia. The analysis was based on standard phytosociological records according to Braun-Blanquet. Different types of crops were included, both row crops (maize, sugar beet, potato, vine, sunflower) and dense cereals such as wheat and barley. An analysis of 552 records was made, to find quantitative rela...

Despite numerous future promises, there is a multitude of concerns about the impact of GM crops on the environment. Key issues in the environmental assessment of GM crops are putative invasiveness, vertical or horizontal gene flow, other ecological impacts, effects on biodiversity and the impact of presence of GM material in other products. These are all highly interdisciplinary and complex iss...

We propose an econometric model of crop choice in which a farmer’s profit-maximizing crop depends on physiological crop attributes interacted with local soil and climate characteristics. We estimate the model using county-level data on average crop choices for 1986–2008. We find that attributes of chosen crops correlate as expected with geographic variation in soil and climate characteristics. ...

As it is well known, Monitoring and controlling of green house parameters plays a crucial role for quality production of crops. Different techniques have been developed in past for actual monitoring and controlling of major green house parameters such as temperature, humidity, soil moisture, light intensity and CO2 in atmosphere. Controlling of parameters is done by means of relays. The main ta...

The genetic modification of crop plants from the methodology involved in their production through to the current debate on their use in agriculture are reviewed. Techniques for plant transformation by Agrobacterium tumefaciens and particle bombardment, and for the selection of transgenic plants using marker genes are described. The benefits of currently available genetically modified (GM) crops...

Cropland diversity has diminished with the advent of mechanized agriculture. In some cases, a single crop is grown year after year in the same field. The lack of diversity in crops rotated in a field has allowed pests to build up, reduced yields, and in some cases increased soil erosion and reduced soil quality. Recognizing these problems, efforts are underway in many farming regions to add mor...
