Abstract

One of the main problems in crop production in our country is the huge gap between farmers' actual yields and potential yields. Inappropriate management, in many situations, yields a significant difference that can be accounted for. Studies have shown that the first step in reducing the performance gap is to identify the performance constraints in a particular area. Understanding performance constraints can help us reduce performance gaps. Reducing the yield gaps not only helps to increase yield and production but also improves the use of land and labor, reduces production costs, and increases performance stability. This study was conducted in 2017 in the Shushtar area to estimate the potential and yield gap performance of wheat (Triticum aestivum L.) plant, as well as the factors limiting the yield and the contribution of each of these factors to the creating yield gap, based on the information and the yield gap collected through a questionnaire and collecting data from the fields of Shushtar area using the method of analysis Functional Comparison (CPA) was reviewed. The real mean of the yield from fields in the Shushtar area was about 3880.38 kg ha-1 and the potential yield of farms was about 9092.78 kg ha^-1 the difference between them was 5212.43 kg ha-1. In addition, the results showed that the factors causing the yield gap were important in order of importance including nitrogen percentage of soil (27.09%), soil acidity (25.57%), drainage and flooding (17.93%), soil salinity (11.73%), weed density (9.38%) and nitrogen stem content before flowering (8.30%) On the yield gap the effect on the fields was affected.
