Abstract:

In order to investigate the effect of different levels of superabsorbent and auxin hormone on yield and yield components of mung bean, a split plot experiment in the form of randomized complete block design with four replications was carried out in the research field of Islamic Azad University, Ahvaz Branch in the summer of 2011. The main plots included three levels of superabsorbent (0, 60, 120 kg/ha) and sub plots were three levels of auxin hormone (0, 10, 15 ppm). The results showed that simple and interaction effects of superabsorbent and auxin on plant height, pod length, grain and biological yield were significant. But the harvest index was only influenced by the simple effect of superabsorbent. Mean comparisons showed that the increase of superabsorbent application up to 120 kg/ha led to the significant increase of above traits by 14.91, 13.26, 11.17 and 18.46 %, respectively in comparison to without application of superabsorbent treatment and application of 15 ppm auxin caused the significant increase of those traits by 14.88, 13.26, 18.67 and 17.71 %, respectively in comparison to without application of auxin treatment. In general, the results of this research showed that the best treatment for optimal yield within the research condition was the one with application of 120 kg/ha superabsorbent and 15 ppm auxin.
