Determination of the effect of plant growth regulators on agronomic characteristics of sweet corn by multivariate analysis

Abstract

Objective: This study was conducted to determine the effects of gibberellic acid (GA3) and sodium nitrophenol applications on agronomic traits in sweet corn. Material and Methods: In the study designed as a factorial arrangement in a randomized block design, foliar applications of GA3 (T1), sodium nitrophenol (T2), and GA3 + sodium nitrophenol (T3) were applied to the plants. Results: Plant growth regulators significantly improved the overall performance of sweet corn compared to the control. T3 treatment provided the highest values by increasing plant height by 30%, leaf area by 17%, cob diameter by 27%, cob yield by 12% and fresh cob yield by 22%. However, the effects of the treatments on cob length and seed number were limited. PCA revealed the significant effect of T3 treatment on vegetative traits such as plant height and leaf area, while correlation analysis showed that these traits had a strong positive relationship with fresh cob yield. Conclusion: In sweet corn, these findings confirm the main contribution of vegetative development in yield increase and the high performance potential of the combined treatment. In conclusion, the combined application of GA3 and sodium nitrophenol offers a promising approach for sustainable yield increase in sweet corn.
