Abstract
To minimize salt stress effect on soybean growth and yield using foliar application of kinetin, an experiment applied in Field Crops Research Station, Tikrit University. Two type of water (river and well), two application of kinetin (kinetin and without kinetin), and four soybean cultivars (Shaima, Laura, Dee and Lee) were used. The Randomize Complete Block Design (RCBD) arranged with spilt plot. The leaf area and leaf area index were calculated 80 days after planting (DAP). At the end of the season, the plant height, dry weight, and yield were calculated. The results showed that the effect of type of water, kinetin, and cultivars and the interaction among those factors were significantly affected the soybean traits. Watering soybean with river water increased leaf area and leaf area index 17%, plant height 12%, dry weight 30%, 100 seed weight 16%, and yield 17% comparison with soybean irrigated with well water. Soybean treated with kinetin increased leaf area and leaf area index 18%, plant height 14%, dry weight 12%, 100 seeds weight 10%, and yield 19% compared without kinetin. Shaima cultivar was higher in most of measured traits. The outcome of this study might be beneficial for the soybean farmers in Tikrit city area.
