The Jackson County trial was conducted on two 29-m-long rows
(two blocks/row). The grafting treatments were randomly assigned
to 3.2-m-long plots within each of the four blocks. Seven plants
were located within each plot, and cultural methods were consistent
with on-farm tomato production for this region. Plants were
spaced 46 cm apart within the row and rows were 1.5 m wide.
Blended preplant fertilizer (8-3-20) was applied as N at 54 kg/ha,
and two Ca(NO3)2 fertigation events were supplied as N at 67
kg/ha on 30 July and 17 August. The Jackson County trial was
initiated on 21 July 2009. Fruit was harvested on 23 and 29
September, and 6 and 15 October. All tomato fruit were harvested
and graded as marketable or nonmarketable based upon on-farm
standards, and fruit weight and number were recorded for each
grade. On the final date, all fruit larger than 5 cm were harvested
and recorded.
