Research Plot Planter with Wide Versatility1

Field research with small grains or row crops often involves a number of different treatments at planting. Since no presently available, or previously described, individual planter provides all the flexibility needed for a wide range of experiments, a planting unit was constructed that permits simple changes in species, cultivars, seeding rates, row spacing, and fertilizer rates and materials. The three-point hitch mounted unit consists of a steel framework with seven double disk coulters, two fertilizer boxes, a cone-spinner and distributor, and an operator's seat. The planter can be adjusted to plant plots ranging from 1 to 75-m long at any seeding rate and with row spacings of 16, 36, 54, and 72 cm. Fertilizer rates of 20 to 800 kg/ha can be applied through each box. A number of crop species, including forages, have been successfully planted with the machine over the past 2 years. The unit is easily transported and can plant as many as 100 8-m long plots/hour.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
