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, …
