Response to planting density for corn hybrids grown under narrow and conventional row spacing
… be managed with population tolerant hybrids and narrower row spacing (e.g., 51 cm vs. 76 cm rows). Narrowing corn rows relieves intra-row competition, and provides the plant with a more equidistant arrangement, this allows the roots more ample space to explore for water and nutrients, and it also …

Integration of Herbicide Programs with Cultural and Mechanical Practices for Managing Glyphosate-Resistant Palmer amaranth (Amaranthus palmeri) in Soybean (Glycine max)
… is the most troublesome weed in Arkansas row crops, causing producers to rely heavily on multiple mechanisms of action to reduce selection pressure for further evolution of herbicide resistance and to successfully produce a profitable crop. It is critical for the sustainability of weed …

The influence of application timing and soybean (Glycine max L.) canopy on imazethapyr efficacy
The possibility of combining narrow row spacings and reduced herbicide rates in no-tillage systems shows promise (DeFelice et al., 1989). However, the issues of the appropriate herbicides to use, proper application timings, and the size of the weeds at the times of application become important …

Full season navigation and control of ultra-compact autonomous ag-bot in GPS denied environment
… is to ensure that the robot can navigate through rows of crops without damaging the plants in narrow row-based and high-leaf-cover semi-structured crop plantations, such as corn (Zea mays), sorghum (Sorghum bicolor) and soybean (Glycine max). The fundamental contributions of this work are a …

Evaluation of Weed Management and the Agronomic Utility of Cotton Grown on a 15-Inch Row Configuration and the Biology and Ecology of Doveweed
… more than a century, farmers planted cotton in rows spaced 91-cm or more apart. Row spacing was dictated primarily by equipment for cultivation, which was initially draft animals and later, tractors. Harvesting equipment also was designed to accommodate these wide row spacings. Recent advances …

Multi-tactic ecological strategies to manage Bassia scoparia and Amaranthus tuberculatus in the cropping systems of Great Plains and Midwestern U.S.
… year’s seed inputs, cereal rye cover crop, and narrow-row soybean on A. tuberculatus density, biomass, and seed production were tested in the 2020 soybean. A weed seed destructor was used to prevent seed inputs by A. tuberculatus escapes at soybean harvest. In corn, an HP with two sites of …

Yield response of soybean to planting date and row spacing in Illinois
… producers. Recent studies of planting date and row spacing have been limited in geographic scope, and few of these have included both factors together. Studies combining these factors, and seeding rate, were conducted during 2010 and 2011 at six Illinois locations. Four planting dates and two …

Soybean seed yield and size as influenced by row spacing and seeding rate and seed-size heritability
… products. This study examined the influence of row spacing and seeding rate on seed yield, average seed size, and seed size uniformity of Camp (small seeded) and V71-370 (large seeded) soybean cultivars [Glycine max (L.) Merr.]. Experiments were conducted in 1992 and 1993 at Kentland Farm near …

Cultivation practices, maize and soybean productivity and soil properties on fragile slopes in Yunnan Province, China
… with polythene mulch and intercropping, wide and narrow row spacing, with soybean in wide row spacing. Crop growth parameters and soil physical properties were measured throughout the cropping seasons. Considering three years data, contour cultivation with polythene mulch generally increased soil …

Agronomic and marker-assisted breeding strategies for improving nitrogen use efficiency in maize
… demand for food increases. However, with the growing concern for food security, maize yield increases must be obtained using more sustainable agricultural practices with less N fertilizer inputs. Improved nitrogen use efficiency (NUE) can maximize maize yield with minimal inputs of N …
