The environmental physiology of tomato (Lycopersicon esculentum Mill. cv. Heinz-6004) and black or eastern black nightshade (Solanum nigrum L. and Solanum ptycanthum Dun.) competition

The growth of the black and eastern black nightshade was analyzed and predictive models were developed. Black and eastern black nightshade were planted on June 3, June 23, and July 12 in 1988 and May 28, June 17, and July 10 in 1989. All plantings were harvested 20, 40, and 60 days after planting, and dry weights and leaf areas determined. Degree-day models accurately predicted the growth of both species for all planting dates. Eastern black nightshade produced significantly more biomass than black nightshade, although the weight of berries was equivalent for both species. Eastern black nightshade responded to self shading by increasing specific leaf area.
