ROLE OF NANO ZINC IN IMPROVING PRODUCTIVITY OF OIL CROPS: A REVIEW

Abstract

Micronutrients that comprises zinc, are much of importance in agricultural production in terms of quality and quantity. Despite the availability of various fertilizer sources such as mineral and chelating for these nutrients along with the availability of different addition methods, however, the efficiency of using these fertilizers does not exceed 5% of the additive. It is necessary to reduce the loss of nutrients in the fertilizationprocess and tending to increase the production in crops, by using nanotechnology and nanomaterials, by using alternative fertilizers rather than traditional and environment-friendly one. that is called nano-fertilizers which is very effective. Nanotechnology is one of the modern technologies that have proven its positive effects in many fields, including agriculture, medicine, engineering, and the field of energy, as they deal with materials and structures of dimensions ranging from 1-100 nanometers. Zinc one of the essential micronutrients in plant nutrition plays an important role in building and growing plants through its participation in many vital processes, including photosynthesis and energy production. It was noted that adding nano zinc to oil crops such as (sunflower, sesame, safflower, flax, rapeseed, soybean, groundnut, cotton, mustard, castor) stimulate and accelerate growth and increase the productivity of these crops of seeds and oil.
