Abstract

Background & Objectives: The aim of this study is to evaluate different hybrids of super sweet corn using various management methods, including herbicide application, plastic mulch, and flame weeding.
 
Material and Methods: This experiment was conducted as a split-plot design based on a randomized complete block design (RCBD) with three replications during the season 2023-2024 at the research farm Agricultural Sciences and Natural Resources University of Khuzestan. Weed management (weedy, weed free, flaming, black plastic mulch, and application of the herbicide nicosulfuron (commercial name: Cruz, 2 L/ha)) was considered as the main plot, and the sub-factor included four super sweet corn hybrids (Altin, Commander, Elite 2, and Shahdab).
 
Results: The results of the interactions showed that there were significant differences in the measured traits among the super sweet corn hybrids and the different management methods. The highest plant height (127 cm) was observed in the Altin Hybrid under plastic mulch application, the longest cob length (17 cm) and the highest number of grains per row (34) were observed in the Commander hybrid under plastic mulch application. The results indicated that herbicide application led to a reduction in plant height, ear length, and number of kernels per ear in all hybrids, with the Elite2 hybrid showing less damage compared to other hybrids. The highest total dry weight of weeds was observed in the weedy treatment in the Shahdab hybrid (279 g/m²), while the lowest was recorded in the plastic mulch treatment in the Commander hybrid (44 g/m²) respectively.
 
Conclusion: Given the reduction in weed biomass and the improvement in traits related to the performance of super sweet corn, the use of plastic mulch can be employed as a tool in integrated weed management for spring cultivation in Khuzestan province.
