Objective 1. To evaluate Sweet Cherry cultivars and rootstocks in combinations for productivity in
the Northeast region.

1999 Progress of Work and Principal Accomplishments

A single planting was established in 1995, and consists of 6 Sweet Cherry Cultivars on 5 different
Gisela Series dwarfing rootstocks. Recent introductions from the Gisela breeding program are being
evaluated for their adaptability to conditions in the Northeast region, in conjunction with cultivars that
show promise for commercial production in the east.

Trees are planted at a 14 x15 ft spacing, and are being trained Central Leader with an emphasis on
minimal inputs.

Due to a severe regional drought, no measurable amounts of rainfall occurred between the end
of May and the end of August. Irrigation was applied on a weekly basis beginning 1 June and
continuing on a 7 day schedule until 30 August, with adjustments being made for stage of growth.

The block was maintained following New Jersey's IPM spray schedule utilizing scouting and onsite
weather.
A handgun application of Lorsban 4E (3 qt/100) was made on 22 Sept. for Peach Tree Borers and
Lesser Peach Tree Borers.

All nutrients were applied as per 1998 foliar and soil test results.
Foliar nutrients: zinc, magnesium sulfate, manganese sulfate, urea, calcium and boron were applied.
Soil applied nutrients consisted of 0-0-50 at 150 lb/A (broadcast) and 34-0-0 at 100 lb/A (broadcast)
this season.
