Abstract
Several methods were used to increase productivity and quality of the product for vegetable crops and prolong their presence in the markets, including the treatment of various vegetable crops with industrial growth regulators and mineral fertilizers, whether fertilizers containing in their composition micronutrients or major nutrients. Global statistics have shown in many studies that there are large numbers of people in the world whose number exceeds 3 billion peoples who suffer from undernutrition, especially the shortage of micronutrients, as this problem can be overcome by adding fertilizers containing these elements to agricultural production fields in different ways, but the use of these chemical fertilizers may have negative harmful effects on the environment and public health in addition to the high prices, which constitute an economic burden on farms, so the researchers moved not long ago to adopt the idea of using nano-fertilizer to raise production efficiency and reduce the harm of biological stresses reduce the cost of production processes as well as it is the safest food source compared to chemical fertilizers in vegetable crops, which have been used and utilized in many scientific fields in many countries of the world. Key word: Nano. Nano-fertilizer. Biological stresses.
