Effect of Herbicides Mixture on Productivity and Profitability of Wheat (Triticum aestivum L.) Cultivation in Rainfed Subtropics

Abstract

Wheat (Triticum aestivum L.) is a vital cereal crop contributing significantly to global food security. The cultivation of wheat in rainfed subtropical regions faces multifaceted challenges, with weed infestation being a primary concern. Herbicides are crucial tools for weed management, and the synergistic or antagonistic effects of herbicide mixtures have gained attention as potential strategies to enhance their efficacy. This review synthesizes existing literature on the effects of herbicides mixtures on the productivity and profitability of rainfed wheat cultivation in subtropical climates. The review systematically analyzes studies conducted globally, focusing on various herbicides combinations and their application methodologies. It encompasses investigations into the ecological impact, weed control efficiency, and effects on wheat yield when utilizing herbicides mixtures. Special emphasis is placed on understanding the interactions between herbicides, considering factors such as climate, soil characteristics, and cropping practices unique to rainfed subtropics. In addition to agronomic outcomes, this review critically examines the economic aspects associated with the use of herbicides mixtures. Cost-benefit analyses, return on investment, and considerations of long-term sustainability are explored to provide a comprehensive understanding of the profitability implications for farmers engaged in rainfed wheat cultivation. The synthesis of this information aims to guide future research directions, inform agricultural practices, and aid policymakers in formulating sustainable strategies for weed management in rainfed subtropical wheat cultivation. By consolidating the current state of knowledge, this review contributes to the development of evidence-based recommendations for optimizing productivity and profitability while ensuring environmental stewardship in rainfed subtropical wheat production systems.
