Kiwiberry, the fruit of Actinidia arguta, has a long history of wild harvest and utilization throughout its native east Asian range, both as food and traditional medicine. Although it is a young crop in terms of commercial development, many studies focused on kiwiberry cultivation and training techniques under different climatic conditions are avai...

Heel wat steden en gemeenten hebben fruit in hun openbaar groen. De verant-woordelijken voor het groen van de steden en gemeenten geloven dat fruit inhet openbaar domein een meerwaarde kan zijn, vooral op vlak van educatie,beleving en sociale cohesie. Fruitproductie op zich is hieraan duidelijk onder -geschikt. Tegelijkertijd geven ze aan dat er no...

Kiwiberry, Actinidia arguta Grower’s Manual is a compendium of knowledge and cultivation of kiwiberry with different aspects in mind, from the knowledge of the plant’s biology, through the selection of the place and the establishment of the plantation to its cultivation. An important part of the study is the subject matter related to the production...

Kiwiberry (Actinidia arguta ((Siebold et Zucc.) Planch. Ex. Miq)) is – just like the green (A. chinensis var. deliciosa) and yellow kiwifruit (A. chinensis var. chinensis) – a fast growing deciduous climbing plant that requires adequate fertilizer management for optimum orchard production. However, compared to kiwifruit, very little is known about...

Commercial production of kiwiberry (Actinidia arguta) started in the early 1980s and it is therefore a relatively new crop. The grape-sized kiwiberry can be eaten without peeling, is tasty, and contains numerous pro-health chemical compounds, positioning it in the lead of the most nutritious fruits in the world. The area of kiwiberry commercial cul...

With the cumulative gas production technique (Theodorou et al ., 1994), the amount of gas released as an end-product of substrate fermentation is measured at regular time intervals, as a measure of the kinetics of fermentation. CO 2 is released both directly as a result of the fermentation and indirectly from the bicarbonate buffer in the medium (B...

Rumen microorganisms have variable requirements for a nitrogen source. Cumulative gas production (Theodorou et al. , 1994) is often measured using media containing both ammonia (NH 3 ) and mixed peptides (trypticase-TRYPT) to ensure that all microbes will have sufficient nitrogen (N) of the appropriate quality for growth and metabolism. This experi...

Kiwiberry (Actinidia arguta) is a new product on the market with a growing consumer acceptance worldwide. Kiwiberry world production is very dynamic and difficult to estimate because only limited printed statistics are available.Therefore, this paper summarizes information on kiwiberry production obtained mainly from growers, coordinators and whole...

The kiwi berry is a relative new fruit crop in Belgium. As for other fruit crops a number of horticultural practices (such as pruning, frost protection, pollination techniques, fertilization, etc.) have to be applied and a knowledge of the crop phenology in our region can support these techniques. The phenological stages from dormant vines to fruit...

Kiwiberry (Actinidia argute), a smaller cold hardy cousin of the well-known kiwifruit (A. deliciosa and A. chinensis), has always been considered of minor economic importance. Its twining, woody vines produce small, grape-size fruit with diversity of flesh and skin colours. With intense flavour, kiwiberries can be eaten whole, without peeling and t...

Commercial production of the kiwiberry (Actinidia arguta) is relatively new in northern and western Europe. When introducing the kiwiberry to a region where fruit growers have no experience with Actinidia, many challenges have had to be overcome. For instance, the profile of the growers willing to invest in this crop is very diverse, the geographic...

Kiwiberry, also called hardy kiwifruit, Actinidia arguta ((Siebold et Zucc.) Planch. ex. Miq), is a new, commercially grown species. Kiwiberry is known for its frost resistance and relatively small, smooth skinned fruit that can be eaten whole, without peeling. Sometimes it is called a 'healthy fruit' because it contains a lot of pro-healthy consti...

Actinidia species show a relatively high uptake of N, K, Cl and Ca. Nitrogen is an important nutrient for good cane growth, but too much nitrogen causes excessive vegetative growth, poor yields, and increased winter injury. Applications of nitrogen at the end of the fruiting season enhance fruit size but are discouraged as fruit then tend to store...

The effect of humic substances on yield and nutrient uptake of grass, maize, potato and spinach was investigated in six field experiments and two pot experiments in a high input cropping system. The humic substances originating from leonardite formations in Canada were applied as liquid solution to the soil (Humifirst liquid) or as a solid incorpor...

Recently developed time-related gas production techniques to quantify the kinetics of ruminant feed fermentation have a high resolution. Consequently, fermentation processes with clearly contrasting gas production kinetics can be identified. Parameterization of the separate processes is possible with a suitable multiphasic model and modelling metho...
