Abstract

In order to investigate the effect of agronomic management on grain yield and quality and economic efficiency of grain maize production, a field experiment was conducted in year 2021. In this study, 10 hectares of field was selected in the Sorkheh region of Shush country, located in the north of Khuzestan province, so that five hectares of this field were cultivated using technical programs and research recommendations and the other five hectares were cultivated by the farmer based on conventional management and local customs. Agronomic evaluation was performed by measuring quantitative and qualitative traits of the crop, and the statistical difference between traits under research-recommended and conventional management was determined using the student's t-test. Economic evaluation was also performed using profitability indices and physical and economic water productivity measurements. The results showed that the yield and grain protein in the recommended field were 27.6 and 21.41 percent higher than in the conventional field, respectively. Also, the components of grain yield including number of ears per plant, number of rows per ear, number of grains per row and weight of 1000 grains in the recommended farm were significantly higher than the conventional farm. The percentage of product sales yield and percentage of return on investment under the recommended management were 49.3 and 97.2 percent, respectively, and under conventional management were 14.8 and 17.3 percent, respectively. The benefit-cost ratios of crop production under the recommended and conventional management were estimated to be 1.97 and 1.17, respectively, and the economic water productivity were estimated to be 16174.6 and 3380.2 rials per cubic meter, respectively. Overall, the results of this study showed that with the application of research recommendations, crop yield and profitability in the target area have increased.
