Abstract

The management of weeds remains a critical aspect of agricultural production, particularly in rainfed subtropical regions where weed pressure can significantly impact crop yield and economic returns. This study aimed to evaluate the effects of combined herbicide applications on both the yield and economic viability of wheat (Triticum aestivum L.) in subtropical rainfed agricultural systems. Field trials were conducted over two consecutive growing seasons, employing a randomized complete block design with four treatments: (1) pre-emergence application of herbicide A, (2) pre-emergence application of herbicide B, (3) combined pre-emergence application of herbicides A and B, and (4) control (no herbicide application). The study assessed various parameters including weed density, wheat yield, and economic returns. Results indicated that the combined pre-emergence application of herbicides A and B significantly reduced weed density compared to individual herbicide applications and the control, consequently enhancing wheat yield. Furthermore, economic analysis revealed that the combined herbicide treatment resulted in the highest economic returns compared to individual herbicide applications and the control, indicating its economic viability in rainfed wheat cultivation in subtropical regions. These findings underscore the importance of integrated weed management strategies, particularly the judicious use of combined herbicide applications, for optimizing wheat yield and economic sustainability in subtropical rainfed agriculture.
