The growth and fruit yield of many trees are totally depended on several factors, including environmental and soil conditions, cultivars, agricultural operations particularly the fertilization and irrigation, as well as the tree nutritional status. Many wrong agricultural operations might cause serious problem for the crop productivity like cracking in fruits. Many strategies for protecting crop from cracking fruits and its management are essential to guarantee producing the high yield. The application of nanomaterials to overcome a lot of problems facing crop productivity especially abiotic/biotic stress has been confirmed by several studies. Nanofertilizers as nanomaterials have several benefits, which can support the crop production under stressful conditions through improving shell life, quantity and quality of crops, increasing nutrient use efficiency and plant bioavailability and extending the duration of nutrients release into rhizosphere up to 30-50 days. The using of nanofertilizers for cracked fruits is still a new approach in fighting fruit cracking, which needs more investigations. These studies open many questions including which kind of nanofertilizers could be used against fruit cracking? And which applied dose could be used and when?
