Comparison of the Yield and Yield Components of Four Imported Soybean Cultivars from Brazil with Domestic Cultivars in Khuzestan
Research/Original Article (دارای رتبه معتبر)
Given the importance of the soybean plant in supplying the country's oil, Gelareh Kalhor Agriculture Company, in cooperation with the Ministry of Agricultural Jihad, imported 4 cultivars of soybeans resistant to heat stress from Brazil and evaluated them in various tests. The present plan has compared the yield and some yield components of imported cultivars with 4 internal cultivars. This experiment was laid out in the form of a randomized complete block design with three replications on a farm on the outskirts of Safi Abad Dezful Research Center in the summer and fall of 2022. For this purpose, imported cultivars including BRS284, BRS232, BRS391 and BRS511 were compared with internal cultivars of Caspian, Rahmat, Saland and SK93. The results showed the superiority of imported cultivars compared to internal cultivars in most traits. Group comparisons between imported and internal cultivars showed that in the traits of the average number of pods per plant, thousand seed weight and yield, imported cultivars were higher than internal cultivars by 20.5, 29 and 35% respectively. The first pod setting height which indicates the harvest efficiency with the combined machine in all imported cultivars was higher than 20 cm. The yield comparison between different cultivars showed that all the imported cultivars had a yield higher than 3000 kg. The highest yield was obtained from the BRS511 cultivar at the rate of 3853 kg, followed by BRS284 (3575 kg) and Caspian (3339 kg). Besides that, the results of the correlation test between different traits with yield showed that the yield has the highest correlation with the average weight of 1000-seed (71%) and with the number of pods per plant (57%). In general, the results of this research revealed that the imported cultivars have a high potential in terms of production and in the future, they can become popular cultivars among farmers.
