This article is a review of the current status in planting and transplanting equipment and practices for vegetable crops. A review of horticultural and agricultural engineering literature is supplemented by information from an informal survey of members of American Society of Agricultural Engineers (ASAE) committee PM-48, Fruit and Vegetable Production Engineering, and other engineers and horticulturists working in this field. Areas covered include precision seed metering, seed placement, and high-speed transplanting with automated plant handling.

An Earthway garden seeder (model 1001B) is frequently used for seeding small research and demonstration plots as well as home gardens. Seeding uniformity tests were conducted with 18 species of vegetable in this seeder using the planter plates recommended by Earthway, alternate plates, and plates modified by taping off metering ports to change the seeding rates and spacings. Performance with the Earthway seeder with most vegetable seeds would not qualify it as a precision seeder, but the Earthway seeder can do an acceptable job of planting many vegetable seeds in small plots at less than 1/10th the cost of a commercialquality precision seeder. A table giving specific recommendations for each of the 18 species has been prepared to aid research and extension personnel as well as home gardeners.

intragenic crops ( Ledford, 2013 ); but no cisgenic plants have been reported ( Holme et al., 2013 ). Indeed, it has been suggested that cisgenic or intragenic plants should not be regulated as transgenic but perhaps by a separate, but as yet undefined

Elderberry [ Sambucus nigra L. ssp. canadensis (L.) Bolli] is a high-value crop that is grown and processed into products for niche markets ( Charlebois et al., 2010 ; Mohebalian et al., 2012 ). Elderberry plants are fruit-bearing, multi

A variety of techniques and vegetative materials are used to asexually propagate blackberry. Blackberry plants can be easily reproduced from root suckers, crown division, root cuttings, tip layering, soft stem cuttings, and tissue culture (TC

Yields of bare-rooted ‘Festival’ strawberry plants in southeastern Queensland, Australia, were best with a planting in mid-March, with lower yields with earlier or later plantings ( Menzel and Smith, 2011 ). In contrast, large plants with crown
