Different chemicals, fertilizers and stimulus are used for boosting productivity of plants. Their application causes the contamination of raw materials for food production with toxins that is dangerous for human health. Therefore, we need developing and implementing new methods for quality assurances and for safety purposes. Magnetic Field treatment is eco-friendly. The results in this study indicated that magnetic treatment prior to sowing applied to dry okra seeds enhanced the growth of okra plant and improved their pod yield and other parameters. Hence, magnetic treatments prior to sowing exerted positive effect on growth and yield parameters of okra crop.

Nitrogen is a macro-nutrient, essentially required for plant growth. It is actually part and parcel of certain macromolecules like protein. So it is required by the potato plant in substantial amount. In this way a managed supply of nitrogen fertilizers is a great strategy for obtaining economic yield of potato crop. On the other hand potato is an important crop of Pakistan and world as well. In some areas of Europe it is staple food.
