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...

BACKGROUND Plant domestication occurred independently in four different regions of the Americas. In general, different species were domesticated in each area, though a few species were domesticated independently in more than one area. The changes resulting from human selection conform to the familiar domestication syndrome, though different traits making up this syndrome, for example loss of di...
