Low cotton (Gossypium hirsutum L.) prices and high production costs have triggered interest in alternative cotton production systems in Mississippi with the predominant goal of increasing returns. Cropping adjustments being used include ultranarrow row, no-till, reduced tillage, skip-row, and wide-row production systems. Fewer linear feet of row per acre suggests potential savings in seed, chemical, and harvest costs and increased returns if yields can be maintained near that achieved on a solid planted basis. Field studies were conducted at the Delta Research and Extension Center in Stoneville, MS and at the North Mississippi Research and Extension Center in Verona, MS to evaluate easily adaptable row spacings compared to 30- in. solid row pattern in 2001 and 2002. An early maturing variety, PM 1218BR, and a mid-maturing variety, DP 458BR, were evaluated in 30-in. solid, 30-in. 2×1 skip, and 30-in. 1×1skip (60-in. solid) row spacings in both years. Additionally, the varieties were evaluated in 40-in. solid, 40-in. 2×1 skip, and 40-in. 4×1 skip at the Stoneville location in 2002. [ABSTRACT FROM AUTHOR] |
