Seeding Rate, Row Spacing, and Nitrogen Rate Effects on Perennial Ryegrass Seed Production
Crop Science, 2015ABSTRACTSeeding rates (SRs) and row‐spacing widths (RSWs) in perennial ryegrass (Lolium perenne L.) seed production are variable and the impacts of these factors on perennial ryegrass seed yield and plant growth characteristics are not well characterized.

RATES OF SEEDING IRRIGATED PASTURES
Canadian Journal of Plant Science, 1959An experiment to determine the effects of different rates of seeding on stand establishment and early yield of an irrigated pasture mixture was conducted from 1953 to 1956. The seed mixture used, in parts by weight, was: smooth bromegrass 7, orchard grass 7, creeping red fescue 4; and white Dutch clover 2. Plots 6 ft. by 30 ft. were seeded at rates of

Inland saltgrass [Distichlis spicata var. stricta (L.) Greene], native to the western United States, has potential for use as a turfgrass and a revegetation species on saline sites. This study was conducted (i) to evaluate the effect of seeding date, seeding rate, and seed treatments on saltgrass establishment; and (ii) to determine the required ...

Winter Cereal, Seeding Rate, and Intercrop Seeding Rate Effect on Red Clover Yield and Quality
Agronomy Journal, 2007Diversification of corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] cropping systems can be achieved by incorporating winter cereal grains. Winter cereal grain production systems in the northern USA are inefficient in respect to annual radiation capture because the majority of these fields lay fallow until the following cropping season. The addition

Optimizing seed rate and stem density for seed potato production
The Journal of Agricultural Science, 1985Previous investigations (e.g. Bates, 1935; Singh, 1952; Bremner & Taha, 1966; Sharpe & Dent, 1968) established that increase in the size of potato seed planted and decrease in inter-sett spaoing increased the number of stems and of tubers, resulting in yield advantage generally, but reduced tuber size in the produce.

Epigenetic mechanisms regulating seed germination rate
Cytology and Genetics, 2017Changes in epigenetic polymorphism degree within wheat seedlings’ population under radiation stimulating exposure of germination were investigated. Variations in seeds sample allocations by germination rate in both control and chronically exposed variants were estimated.

Modified Seed Maturation Rates and Seed Yield Potentials in Soybean
Crop Science, 1992Seed embryos of soybean [Glycine max (L.) Men‐.] genotypes can have different levels of specific dry matter accumulation rate (SDMAR) and specific seed density (SSD) under greenhouse growing conditions, but the relevance of these measures for field‐grown plants is not known.

Estimating seeding rates and harvest losses
Journal of Agronomic Education, 1979ABSTRACTSeeding and fertilizer application rates should be checked before and during operation in order to achieve the most economic and productive crop yields. Broadcast rates can be determined from tabulated values or calculated from formulas after sampling small representative areas.
