The founder of Westfalia, Dr Hans Merensky (HM), expressed the wish that international exchange in research should be promoted through Westfalia and the Hans Merensky Foundation. Therefore, WTS has the opportunity to invite a renowned researcher to Westfalia to enable interaction and sharing of international knowledge and experience. In the past, WTS had among others Prof John Menge and Dr Mary Lu Arpaia (both from the University of California Riverside), Prof. Dov Prusky (University of Jerusalem in Israel) and Dr. Richard Campbell (Fairtrade institute in Florida) visiting Westfalia as invited HM Fellows.
For the 2013 Fellow, WTS invited Dr. Iňaki Hormaza from Spain. Professor Hormaza is head of the Institute of Subtropical Fruit research at the University of Malaga with key interests in molecular tools for fingerprinting, breeding and germplasm conservation in temperate and subtropical fruit tree species; as well as the reproductive biology of temperate and subtropical fruit tree species with special interest in the effects of climate change on reproductive biology and pollen-pistil interactions. His avocado-specific research focuses on pollination of flowers; specifically the effect of starch content of avocado styles and its’ effect on pollen tube growth and pollination.
Dr. Hormaza visited Westfalia Fruit Estates from the 6th of May 2013. To facilitate and encourage international cross-pollination of research ideas, WTS also invited a few selected guests to contribute to a week-long technical session. These guests included Dr. Mary Lu Arpaia (University of California Riverside), Dr Elizabeth Dann (Queensland Alliance for Agriculture & Food Innovation, Australia), Dr. Monica Castro (Catholic University of Valparaiso, Chile) and Dr. Noelani van den Berg (University of Pretoria, Forestry and Biotechnology Institute). Also attending was a team from the Californian avocado nursery (Brokaw Nursery), which included Rob Brokaw and Dr. Octaviano Lemus.
The team of international visitors, in conjunction with the WTS research team, spent five days in various Westfalia Fruit Estate orchards and related facilities discussing a wide range of topics relevant to the management of the avocado supply/production chain. The visit by the 2013 HM fellow and his accompanying guests ensured that not only was the newest knowledge on avocados was exchanged, but it also strengthened the important collaborative bonds that WTS had developed with key institutions throughout the past few decades.
Hosted on Westfalia Estates, the studygroup meeting drew Carmen®-Hass growers from the whole producing area. The event proved an ideal opportunity for growers to understand how to determine when to pick Carmen®-Hass, especially with more than one set on the trees.
Carmen® tends to flower more than once per growing season, with a pronouned out-of-season flower that produce fruit maturing November to January. Also, from continuous moisture content samples taken, it appears that Carmen®-Hass in-season fruit starts to mature from week 8 onwards, which means that the first 2013 export Carmen®-Hass crop may be picked early in March.
After a quick coffee, Carmen®-Hass growers drove to the nearby Westfalia-Zendelingshoek farm, where 3 year old Carmen®-Hass trees could be seen bearing a large crop ready to be harvested. Here growers could witness first-hand the distinct growth and flowering patterns of young Carmen®-Hass trees, and address questions to any of the available WTS staff. Inidications are that the 2013 season would result in an export crop of more than 50 000 cartons Carmen®-Hass that would extend the normal South African Hass season with a few weeks.




WTS again organized a successful mango club cultivar farmers’ day. Hosted at Bavaria Estate in Hoedspruit, the event provided an ideal opportunity for growers to see club cultivar fruit on trees, and to also increase their knowledge and horticultural understanding of the club cultivars HoneyGoldTM, Princess® and Shelly.
This informal day was held in order for farmers to get more acquainted with the different cultivars, and to taste their potential future produce.
