A vertical cup with split base type metering mechanismwas developed for transplanting cell type nursery. The metering mechanism holds the nursery seedling, dig a hole in the soil at desired depth and releases the seedlings in the hole in near vertical position without any damage. The developed metering mechanism was evaluated in the laboratory for transplanting artificial nursery grown in trays having three different cell sizes 50, 98 and 105 cells/tray at three different feedrates i.e 50, 65 and 80 feeds per minute respectively forthree subjects. Plant missing increased with increase in feed rate for all the subjects and average plant missing for cell C3 and feed rates of 50 plugs/min, 65 plugs/min, and 80 plugs/min was respectively: 0.0%, 0.51%, and 7.92% for subject S1; 2.00%, 1.03%, and 5.00% for subject S2; and 5.33%, 4.62%, and 20.42% for subject S3. However, the effect of cell size on plant missing was non-significant. Plant doubling was observed only for one subject at highest feed rate (2.41%). Quality of feed index decreased with increase in feed rate for all the subjects. The performance of the developed metering mechanism was found satisfactory for planting cell type nursery at 65 plugs/min in the laboratory evaluation
