Sample Budget for Blackberry Production

weeds before planting. Although we assumed 1 quart per acre of glyphosate at $10.7 per quart

you should read the label for the application rate.
When determining row and plant spacing, it is important to remember that these decisions will
determine the number of plants per acre. For the budget, a 12-foot space between rows and a 3-
foot space between blackberry plants is assumed. If you are growing more than one variety, it
would be appropriate to use the same space between rows and plants regardless of the varieties
grown for management purposes. If there is variation in space between rows and plants, mowing
and other activities that require specific equipment sizes may become more complicated or
laborious.
We assumed the blackberry varieties grown are Natchez and Ouachita. Natchez is a semi-erect
thornless variety, while Oachita is an erect thornless variety. These two varieties are high-
yielding, high-quality, and are great for commercial and local markets
5
. The harvesting period
for both varieties is June to August, but Natchez ripens about a week earlier (around June 3) than
Ouashita
6
. Exact harvesting times will vary from year to year and by the location of the
operation. There are no differences in management strategies between the varieties as trellis
systems are recommended for both varieties. There are benefits of combining these varieties
because Natchez is more sensitive to freezing temperatures than Oachita, and therefore
combining the two varieties might help to manage weather risks. Additionally, combining
varieties may create additional marketing opportunities as it extends the marketing season.
When assuming a 3-foot-by-12-foot spacing (i.e., plant space times row space), 1,210 plants at
$4.11 each are transplanted. Blackberry plant prices are estimated by taking the average of plant
prices from nurseries in Indiana and Arkansas. We assumed transplanting happens in early spring
(March) of Year 2. The 1,210-plant density is appropriate for u-pick operations. We allocated 36
labor hours for transplanting blackberry plants into the field

. Canes produced from the
blackberry plants in Year 2 (primocanes) will not bear fruit.
For cane support and to keep the fruit off the ground, a wood T-trellis system is assumed to be
used. Trellis systems are useful in maximizing sunlight exposure, air movement and spray
penetration throughout the canopy. Additionally, trellis systems can facilitate planting
management or make harvesting and floricane removal easier. In general, using trellis systems
can maximize yield and minimize labor use. Although we assumed a wood T-trellis system for
this budget, there are various trellis systems options
