Wheat Yield Gap Assessment in Using the Comparative Performance Analysis (CPA)

One of the crucial issues in developing nations is diminishing yield gaps. Therefore, accurate gap estimation has many real-world uses for increasing crop production. Utilizing comparative performance analysis (CPA) techniques, wheat fields was evaluated this study. In Varamin, Tehran Province, Iran, data on 104 were collected between 2018 and 2020 every aspect field management been documented. The CPA model determines gap’s contributing factors potential yield. results revealed that production ranged from 2600 to 7600 kg ha−1. method predicted a 9316 ha−1 found 3748 ha−1; amount 40.23% Leaf chlorophyll (29%), irrigation at stem extension (9%), LAI (7.7%), soil salinity (8.2%), area (16.3%), phosphorus consumption (6%), nitrogen utilized stage tillering (16%), HI (7.8%) all contributed CPA. It said computed can be reached. cheap straightforward tool could identify gaps their causes district without need costly experiments. with significant efficiency use these techniques effectively.
