Abstract

Cone, belt, and baffle planters built to fit on standard Planet Jr. planting units, were evaluated for vegetable plot seeding. On the basis of field tests with cabbage, cucumber, and lettuce seed, the belt planter was preferred. The cone planter had difficulty in transferring seed from the cone plate to the delivery tube and the baffle planter did not seed cabbage and lettuce uniformly.

Abstract

A commercially available small garden seeder was modified to improve the precision planting of uncoated lettuce seed. The modified seeder is light weight, is adapted to planting small quantity seed lots, can be rapidly cleaned of remnant seed, and is designed for research and home garden use. Acceptable single seeding of uncoated lettuce seeds in the laboratory averaged 41.5%. Acceptable single seedling emergence in the field averaged 36.8%, a 13.6% improvement in the existing efficiency over the small plot seeder currently used. Minor modifications could make this planter design adaptable to most small-seeded crops.

Abstract

Depending on soil-surface conditions, an electronic pick-up and counting device to signal within-row tree distances using a mechanical tree planter produced planting distances as accurate or more accurate than those obtained with traditional planting techniques.

Three intercept surveys were conducted at the Penn State Southeast Research and Extension Center in Landisville, Pa., at three separate field days during the period of 28 July 2004 to 4 Aug. 2004 to determine grower (n = 78), retailer (n = 52), and consumer (n = 55) preference for annual planters. Survey participants were self-selected and asked to answer questions evaluating both their preference for and past experience with purchasing annual planters, as well as sociographic and demographic questions. Growers who were 45 years of age or younger were more likely to take price into consideration when creating an annual planter (68.8%) than those who were 46 years of age or older (43.3%), but less likely to use point-of-purchase material to educate consumers on proper container care (45.2% and 75.0%, respectively). Additionally, retailers whose business was 89% retail or less were less likely to consider price when creating annual planters (53.3%) than those participants whose business was 90% retail or greater (84.2%), and were also found to be less likely to use point-of-purchase material to educate consumers on proper container care (46.7% and 72.2%, respectively). Consumers were more likely to consider price when purchasing an annual planter if they were female (92.7%) than if they were male (66.7%). Consumer participants who resided in single-family homes were more likely to take the color combination into consideration when purchasing annual planters (100.0%) than those who live in another form of housing (e.g., apartment or mobile home; 66.7%). Additionally, consumers who live in single-adult households were less likely to consider color combination when purchasing an annual planter (88.9%) than those who live in households with two or more adults (100.0%).

A mechanical planter was developed to sow seed of baby lima beans (Phaseolus lunatus) in small plots. The mechanical seeder allowed small plots to be quickly and consistently seeded at a fixed spacing. Seeds were manually spread along a 10-ft (3.0 m) base plate containing 50 holes of slightly larger diameter than the seed length and at the desired seed spacing [2.4 inches (6 cm)]. Once all the holes were filled, a slider plate below the base plate containing holes of the same diameter and spacing, but which were slightly offset, was slid horizontally so that the holes of the base and slider plates aligned and the seeds dropped to the bottom of the furrow. Compared to manual planting, the mechanical planter increased the precision of seed placement and reduced the time needed to plant 50 seeds. The planter was easy to use and transport, and was inexpensive.

Prior studies have demonstrated that a Gaspardo vacuum seeder provides less uniform seed spacing than a Stanhay belt seeder. It was hypothesized that the difference was primarily because of the greater seed drop height on the Gaspardo seeder. A Gaspardo metering unit was modified by adding a slide or an enclosed tube to guide the seeds from the release point (seed plate) to 1.0 inch (25 mm) above the bottom of the seed furrow. Seed uniformity tests were conducted with cabbage (Brassica oleracea), onion (Allium cepa), and mustard (Brassica juncea) seeds. The modified planter unit was compared with an unmodified unit. No improvement in seeding uniformity was noted with either the slide or the tube. In fact, seed placement uniformity was degraded with the addition of the slide and tube. Although it is probable that the seed spacing nonuniformity was caused by drop height, attempts to control the seed trajectory were unsuccessful.

Abstract

Research involving fluid drilling, the metering and planting of germinated vegetable seeds suspended in a gellike fluid, has been underway for several years (1, 3). A hand-operated, ground-driven, combination fluid drill and dry seed planter for small plot work (Fig. 1) is currently being used as a result of a joint project of the Oklahoma State University Agricultural Engineering and Horticulture Departments. The design is similar to machines described by Lickorish and Darby (2) and by W. L. Albring3 incorporating both a fluid metering unit and a cone-type dry seed metering unit into a single light-weight machine to expedite the planting of dry and germinated seed plots using the same furrow opener. Ease of operation and adjustment was considered during the design along with reliability and durability. The machine can be quickly adjusted to apply fluid rates of 10, 20, 40, 60, 80, and 100 ml/m of row length and dry seed metering rates of 3, 6, 9, and 12 m of row length per cone revolution.

Abstract

A compressed air gel seeding system was developed to sow simultaneously several rows with different seed treatments. A technique to plant vegetable seeds at equidistant spacings using a solenoid valve and photoelectric device is described.
