Hand-held thinning tool

  • April 1st, 2010

Much of the research in orchard innovation involves automation and robotics, but not every orchard can accommodate technology like mechanized harvesters and mechanical thinners. That’s why a Washington State University engineer is also looking for technology that could augment hand labor.

Dr. Qin Zhang, a biological systems engineer for WSU, [...]

Retrofitting an apple packing line

  • April 1st, 2010

A Yakima, Washington, grower-packer operation wanted to upgrade its optical sorting capability but didn’t want to make expensive changes to the entire line. By retrofitting the outdated optics with a new system, color and size grade adjustments can now be made quickly with a few computer keystrokes.

Dream tractor?
The Mach 4 is an articulated reversible quad-track vehicle for specialized farming. Launched in Italy in 2008 as a “dream tractor,” it is now one of the leading models that Antonio Carraro produces. It is a universal vehicle designed to handle extreme working conditions on any kind [...]

  • Chemical thinners are inconsistent

Chemical thinners are inconsistent

  • April 1st, 2010

Penn State’s Dr. Jim Schupp says that the inconsistent results with chemical thinners led to researcher interest in mechanical thinners.

After a decade of searching for effective chemical blossom thinners for Pacific Northwest stone fruit growers, researchers are still empty-handed.

The Washington Tree Fruit Research Commission has evaluated chemical thinners for [...]

Reduce compaction

  • April 1st, 2010

Juice grape growers in Washington State have found a way to aerate the soil, relieve soil compaction, and reduce farming costs.

An aerator implement that uses metal fingers to loosen the soil is finding favor in the grape industry. Forage and grain crop farmers have found the implement is useful in [...]

Irrigation options

  • April 1st, 2010

Plantings at Yakima Valley Orchards are irrigated with drip. Travis Allan checks on a Honeycrisp block planted in 2007 where overhead sprinklers are being installed for frost protection.

An increasing number of orchardists are using drip irrigation systems to get their new orchard blocks off to a good start.

  • The lowdown on drip

The lowdown on drip

  • April 1st, 2010

Drip irrigation systems are designed to deliver water precisely and uniformly to the crop roots and often results in water savings. Water is applied in low volumes at frequent intervals.

There are two types of drip systems: a rigid drip tube that can be used as a permanent system and [...]

Searching for cherry cracking strategies

  • February 15th, 2010

When researching rain-induced cracking of sweet cherries, it’s obvious that rain is a requirement. Two years of research, though yielding little rain-induced cracking, have shown potential for reduced cracking from some materials, as well as a varietal difference in the timing of susceptibility to cracking.

The Washington Tree Fruit Research [...]

Stretching storage of Honeycrisp

  • February 15th, 2010

As production volumes increase for Honeycrisp apples, the need for a longer marketing window becomes more important. Researchers like Ines Hanrahan are looking for ways to stretch storage of Honeycrisp beyond Christmas.

With consumers and retailers clamoring for the popular variety, growers have responded to the strong demand by planting [...]
