| Summary: | 0, 1 , 2, 3, 4, 6, 8, 10, and 12 plants per 9. 14 m of 25%. . Cotton lint qualities, including micronair, 650. Intraspecific competition was not evident in amaranth evaluated in this experiment. and 6 Palmer amaranth per row, however, densities and development in Central Texas. Growth and and position of bolls were not significantly at mid-season was erratically affected by 1, 2, 3, 4, away from a Palmer amaranth plant.were mapped for biomass accumulation at the densities of Palmer By the end of the season, the Palmer amaranth biomass competition on cotton (Gossypium hirsutum L.) growth competition with Palmer amaranth. Cotton shoot biomass cotton variety was Delta and Pineland 50, commonly densities. Palmer amaranth canopy development was not development of both species were measured throughout exceeded 6 versus 0 Palmer amaranth plants per row. exceeding 6 Palmer amaranth plants per greater than 35%. Cotton plants 25, 75. and 1 25 cm grown dryland variety by central Texas area producers. However, the end of the season biomass pooled over influenced at the Palmer amaranth densities evaluated. influenced by Palmer amaranth at any of the distances. length, strength, and uniformity, were not maintained a trend similar to the mid-season biomass. Palmer amaranth (Amaranthus palmeri S.Wats.) Palmer amaranth canopy development or Palmer amaranth densities exceeding 3 Palmer amaranth Palmer amaranth mid-season shoot biomass was plants per row significantly reduced cotton lint Research was conducted to determine the influence of phics. row significantly decreased cotton shoot biomass by row. Cotton canopy was not significantly altered by significantly larger when Palmer amaranth densities significantly reduced by Palmer amaranth at any of the The cotton was planted at 1 62,000 seeds per ha and the cotton-growing seasons of 1996 and 1997. The the Palmer amaranth at total boll set and boll position Total number of bolls years fit a positive linear equation of y = 545x + yields by |
