Abstract:: Vegetable production with a living mulch may reduce soil erosion and compaction, increase organic matter levels, and decrease the requirement for chemical inputs. Competition between the vegetable and mulch, however, has limited the development of successful living mulch systems to realize these benefits. In a field study, interference between pak...

Creator:: Petersen, Terry D.
Abstract:: Computer simulations and experiments were used to determine the basis for skewness and inequality in size structures (frequency distributions of Individual plant sizes) prior to self-thinning mortality. In simulated stands, density-dependent neighborhood heterogeneity caused variability in the growth rate of individuals with the same size, and such variability caused skewness...

Creator:: Wells, Barbara Heard
Abstract:: Time-course growth chamber studies were conducted on little mallow (Malva parviflora L.) to determine whether sublethal doses of lactofen (1'-(carboethoxy)ethyl-5-[2-chloro-4-(trifluoromethyl) phenoxy]-2- nitrobenzoate) would enhance uptake of glyphosate (N'-(phosphonomethyl) glycine) by altering membrane permeability. Lactofen-induced membrane peroxidation was determined by harvesting leaf discs, measuring stress ethylene evolution, and recording increases in...

Abstract:: Field, screenhouse, and laboratory experiments were conducted to study weed interference in rice grown on hydromorphic soils at the International Institute of Tropical Agriculture (IITA) at Ibadan, Nigeria. Rice and weeds emerged at the same time, 1 week after planting. Weed dry weight was significantly reduced when the crop was...
