Plans during project implementation:

  1. The testing of CHAE growing technologies, cultivars and prospective hybrids in production conditions by using knowledge accumulated about cover usage, soil activity based on different fertilizers, plant protection methods;
  2. To figure out the reasons for cultivar and prospective hybrid (in)compatibility and irregular yields by using field methods in the LatHort, “Jansonu saimniecība”, Ltd and farm “Bētras” CHAE plantations;
  3. To reduce manual labour, the “Jansonu saimniecība” will outsource the planting of Japanese quince to the farm “Kalnēji” by using a special machine for the purpose of planting Japanese quince with agrotextile cover, thus planting a new CHAE plantation with LatHort cultivars, prospective hybrids and also with seedlings selected from LatHort for the purpose of improving pollination;
  4. Develop technologies that can be used in industrial production for export-viable products, by using the fruit grown in both farms and LatHort and working with previous technological implementations of LatHort.

Planned results:

  1. The creation of a new product – CHAE cultivar, that, by the end of the project, will be submitted for registration in Latvia and sent to Poland for DUS testing;
  2. Developed growing technologies, including information about necessary pollinators and other agronomic demands for the growing of the developed cultivar and at least 3 other prospective hybrids of LatHort, for the purpose of acquiring high volume and regular yields;
  3. Development of automated planting technology with agrotextile covering suitable for industrial capacity by using seedlings and potted plants, economic calculations have been performed;
  4. Development of technology for acquiring CHAE juice concentrate as a natural acidifier so lower-quality fruit can be used en-masse, quality indicators, nutritional value have been defined, technical specification prepared;
  5. Low-sugar content candied fruit production technology adapted to industrial capacity production;
  6. Candied fruit production technology is improved by increasing their biochemical and nutritional value by adding cherries and raspberries as additives;
  7. Innovative tests are performed for the creation of a new technology that would decrease the presence of pectin in syrup by using enzymes.

The developed growing technology will allow both farms to acquire more regular and higher volume of fruit yield and higher quality fruit. The developed technologies for candied fruit manufacture will increase the competitiveness in local markets of the business involved in the project and develop export opportunities. The development of a technology for juice concentration will be a boon to all CHAE growers, as it would solve the utilization of lower-quality fruit.
