Forage Production and Quality of Forage Sorghum Intercropped with Sunnhemp at Different Seeding Rates
… may be increased. However, the optimal intercrop seeding ratio of sunnhemp to sorghum to improve crude protein content and maintain sufficient biomass is unknown. In 2020 and 2021, a field experiment was conducted using sunnhemp intercropped at three seeding rates (16.8, 33.6, and 50.4 kg ha-1) …

Intercropping Pearl Millet and Soybeans at Various Row Spacings, Seeding Rates, and Cropping Patterns
… fixing species, at various row spacings, seeding rates, and cropping patterns. Pearl millet and soybeans were grown at three row spacings (25, 51, 76 cm), three seeding rates (11, 22, and 34 kg/ha), and three cropping patterns: PM--Pearl millet seeded in a pure stand; SB + PM--Pearl millet …

Soybean Growth and Yield Response to Seeding Rate in Virginia
… generating interest from growers to reduce seeding rates to the lowest possible level that does not affect yield. Research indicates that greater seeding rates are needed to maximize yield under low-yielding environments and less seed is needed in high-yielding environments, but this has not …

Genetic gain X management interaction in soybean: seeding rate effect
… the last 80 years were evaluated at high and low seeding rates in research trials conducted in Illinois, Indiana, Minnesota and Wisconsin. In Illinois and Indiana, 57 maturity group III cultivars released between 1923 and 2007 were compared, and in Minnesota and Wisconsin, 59 maturity group II …

Soybean seed yield and size as influenced by row spacing and seeding rate and seed-size heritability
… 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 Blacksburg, …

Interplanting of a deficient soybean stand
… Columbia, MO and consisted of 5 treatments, 6 seeding rates, and 4 replications. The yield data collected from this study showed that interplanting was a viable option at seeding population of 74 100 per acre. At seeding rates of 148 200 to 444 600 per acre, the "let be" treatment which is …

Effect of different production practices on the development of verticillium wilt and cotton fiber quality
… the effectiveness of different planting dates, seeding rates, and cultivars on suppressing Verticillium wilt; 2) simulate the temporal dynamics of Verticillium wilt in cotton for different seeding rates and cultivars; 3) examine the relationship between wilt incidence, lint yield, and various …

Agronomic Practices to Reduce the Effects of Environmental Stresses on Spring Canola (Brassica napus L.) Establishment and Yield in Ontario
… not found in field trials, even at sub-optimal seeding rates. In a high-yielding greenhouse trial, low plant density shifted much of the pod load from main racemes to branch racemes, but this morphological change did not significantly reduce yield loss under water stress.

Establishment, Forage Production and Drought Resistance of Native Perennial Legumes of the Canadian Prairies
… and soil nutrient levels of mixture plots. In a seeding rate evaluation, the four legume species were planted in monoculture at three seeding rates (300, 200 and 100 PLS m-1) and tested for forage dry matter yield near Swift Current, SK one year after seeding. While increasing seeding rates up to …

Evaluating an Advanced Intensive Management Strategy for Virginia Wheat
… Increases in nitrogen (N) fertilizer application rates and splits, a chelated micronutrient blend, increased seeding rates, and a "no tolerance" pest control methodology were compared to current intensive management practices in this study. Additional fall N application and an increased seeding …

Do benefits from cover crops vary by species or mixture composition?
… species choice for mixtures, and to adjust seeding rates according to their goals, i.e. increase seeding rates for legumes if nitrogen fixation is a higher priority than weed suppression. The use of cover crops in mixture is becoming increasingly popular in organic farming systems. However, …

Examining the effects of seed mix diversity and composition, biochar application, seeding rate, species identity, and topography on Palouse Prairie restoration
… the proportion of forbs to grasses, and seeding rate, and the most effective levels of each are not clear. Further, soil amendments, such as biochar, may benefit properties of tilled soils, but have not explored in Palouse Prairie systems. To address these knowledge gaps and inform …

Study of agronomic factors important to the establishment of various perennial grass bioenergy feedstock species
… for seeded miscanthus by comparing different seeding rates and planting methods under irrigated and rainfed conditions. Drought conditions in both establishment years coincided with stand establishment failure under rainfed conditions, suggesting that seeded miscanthus may not establish well …

The effect of field pea (Pisum sativum L.) basal branching on optimal plant density and crop competitiveness
… crop in western Canada. The current recommended seeding rate in field pea is 88 plants m-2. As certain pea genotypes have the ability for increased branching, it may be possible for a producer to seed at a lower plant population without reduced yield or to choose a highly branched cultivar to …

The effects of rapid establishment and subsequent turf quality of agressive grasses seeded with Poa pratensis L
… 7, 1968, and Hay 13 and July 16, 1969, by seeding three rates (on pure live seed basis [PLS]) of several companion grasses with a constant rate of Kentucky bluegrass (Poa pratensis L.). Mixtures were irrigated and clipped to 1- and 2-in. sod residues. Objectives were to determine which …

Forage Systems for the Southeastern United States: Crabgrass and Crabgrass-Lespedeza Mixtures
… and (2) evaluate the effects of lespedeza seeding rate and N fertilization treatment on the yield, botanical composition, and nutritive value of crabgrass-lespedeza mixtures. A greenhouse study was conducted using three soil pH levels of 4.8, 5.5, and 6.3. Crabgrass germination and root and …
