Abstract
Wheat is a staple food in Pakistan and plays a vital role in the country's agriculture. It is one of the country's most widely cultivated and consumed crops, providing millions of people's food and livelihoods. The study reviewed the literature on the effect of foliar application of zinc on zinc-fortification and the yield of wheat grown under rainfed conditions. The review analyzed a range of studies that investigated the impact of the foliar application of zinc on wheat growth and grain quality. The results showed that foliar application of zinc significantly improves the zinc content of the wheat grain, which has important implications for addressing zinc deficiency in areas where it is prevalent. Additionally, the review revealed that zinc treatment leads to a noticeable increase in wheat yield, demonstrating its potential to improve agricultural productivity in rainfed farming systems. The review concludes by highlighting the need for further research to optimize the application rate and timing of foliar zinc application to maximize its benefits for wheat production under rainfed conditions.
