Abstract
Arkansas cotton (Gossypium hirsutum L.) producers have made progress in sustainable production over the past twenty years with expanded adoption of soil and water conservation practices, including reduced tillage and use of winter cover crops. Producers have been uncertain about the need to modify other practices as they adopt conservation tillage systems, particularly the costly decision on whether to increase cotton seeding rates when they plant into stale seedbeds with high residue from terminated cover crops. To address this question, an on-farm experiment in northeast Arkansas was conducted to evaluate cotton performance with modified cotton seeding rates in rainfed or irrigated and conservation or conventional tillage systems. The multi-factor study included in-season monitoring, yield and fiber quality evaluations, crop enterprise budgets, and sustainability indices. Georeferenced sampling with corresponding soil ECa measures allowed consideration of whether within-field soil variability could interact with treatment factors and affect crop performance.
