Document Summary

Rs 478: lecture 14 planting methods and seeding rates. Outline: planting methods, direct seeding, transplanting, seeding rates, planting methods, plants can be introduced to sites via, natural dispersal (volunteering) - can natural plant dispersal be managed, direct seeding: drill seeding at a specific depth, density and spacing. Broadcast seeding by scattering seed on the soil surface: transplanting of whole plants or plant parts. (more expensive but better results), when planting you must consider best planting time, planting rates, planting depths, methods, cost and equipment. Seeding rates, seed quality, predation, etc: breaking seed dormancy, stratification: exposing the seeds to cold temperatures simulating a short winter. In general, seeding should take place immediately prior to the period of greatest moisture availability: fall seeding (dormant seeding): advantages: equipment access, vernalization, good for cool-season species. Disadvantages: seed predation, seed death, weeds: spring seeding advantages: reduced seed loss, good for warm-season species.
