Conventional, organic and biotech farming are the three main cropping systems in the modern agriculture. The organic farming excludes applications of synthetic fertilizers, pesticides, growth regulators and additives for animal feed. Therefore the production under this system incurs higher costs while the market prices for the end product are also higher than from the other two systems. Conventional farming relies on the achievements of modern chemistry and biochemistry for obtaining fertilizers and pesticides that can help in fighting crop pests. This type of agriculture at present provides about 85% of the agricultural products in the world and guarantees obtaining quality products at acceptable price. Biotech farming is based on the concept of reducing the use of synthetic pesticides through developing resistant varieties and introducing resistances to lower toxicity herbicides to fight weeds. Through eliminating sprays of resistant varieties both ecological from reducing pesticide use and quality effects from avoiding secondary contamination of the injured by pests products are achieved. This results in improving both quality and the economic sustainability of the production under this type of farming, which is evident in the sustained growth rates of the use of biotech farming in the world since it was conceived.
