Practices required for a vegetable crop growing in the field include cultivation; irrigation; application of fertilizers; control of weeds, diseases, and insects; protection against frost; and the application of growth regulators if necessary.
Two hundred and four potato farmers were interviewed about the type and source of pesticides they use in potato cultivation, the frequency of applications, the use of protective clothing, and cases of pesticide poisoning.
Our results indicate that Bt toxins released via the cultivation of Bt crops, the application of Bt pesticides can be adsorbed on paddy soils, and soil texture could impose an impact on the adsorption capability.
The least values of soil, growth and head yield parameters (number of leaf, leaf area, stem height, head length, head girth and head weight) obtained under the control treatment compared to other treatments could be as a result of initial low soil nutrients status that often characterize continuous cultivation of land without fertilizer application.
In recent decades cultivation of flax and its application have dramatically decreased.
Methods employed to control weeds include hand weeding, mechanical cultivation, application of chemicals acting as herbicides, and a combination of mechanical and chemical means.
Through the cultivation of Bt crops and the application of Bt pesticides, Cry proteins could be introduced into arable soils.
Since 1998, the commission has not approved any applications for the cultivation of genetically modified crops, but it has not actively rejected any applications, either, as would be the case with the genetically modified corn products.
Within biomedical applications, cryogels are being used in scaffolds for the cultivation of mammalian cells in tissue engineering applications [15].
This induced either an increase of fertiliser application or increased cultivation of bioenergy crops, such as maize and rape, which were likely to increase stream nitrogen loads.
