Impact of Herbicides and Their Application Techniques on Yield and Residues in Cotton-Based Intercropping Systems

Abstract

Field experiments were conducted at the Agricultural College and Research Institute (Killikulam), Tamil Nadu Agricultural University from September 1992 to June 1995 to optimize the herbicide dose and application techniques for cotton-based intercropping systems.283

Enhancing cotton sustainability: Multi-factorial intercropping, irrigation, and weed effects on productivity, quality and physiology

“…Cotton is a major cash crop with a significant role in global trade and generates substantial revenue in China, India, the United States, Pakistan, Brazil, Australia, Uzbekistan, Turkey, and Africa [ [6] , [7] , [8] ]. According to the Food and Agriculture Organization (FAO), the world's total seed cotton production was around 83 million tons in 2020.…”

“…The extent of the impact depends on factors such as the severity and duration of drought, the type and competitiveness of weeds, and the stage of cotton growth when these factors occur [ 16 , 17 ]. Furthermore, weeds can use 30–50% of applied fertilizer and can also reduce moisture levels by 20–40% [ 6 ]. In the USA, weeds pose a significant challenge in pest management, with 90% of USA farmers and consultants identifying weed management as a top three constraint.…”
