Flowers around apple gardens will get higher yields

Apple's producers should increase the number of flowers around their apple orchards if they want to increase their crops. As a result of a new research by researchers at Stockholm University, shows that more pollinators, such as bees and flowers fly, attract the gardens of flowers – which will increase the expected results of pollination.


The harvest of this summer's apple crop is high and large amounts of organic apples have been expanded. New research on apple gardens in Sweden, Germany and Spain Applied Ecology Journal, Found that wild pollinators and pollination were higher in gardens over flourishing plants.

"Although many nurseries do not contain the number of flower plants, grains can benefit from this change," says Peter Hambak, professor of ecology, environmental protection and plant sciences department at the Stockholm University.

Improved pollination creates more seed, which may increase the time of certain cultures. Researchers believe that by making more seeds in individual apples, changing the mineral content, apple can not be stored anymore. The increase of apple flags is retained after the harvest has great advantages for apple producers, but more research is needed to study this tracking and seed production.

The highest apple crop – is not a threat to biodiversity

Study has shown that the average product of the apple garden apple is lower than using plant protection chemical pesticides.

"However, the surprise results were that the higher production organic garden was more productive than the use of chemical pesticides, indicating that there is potential for more ecologically developed cultures and the same time brings high yields," says Peter Hambac.

Other cultures, such as different grains, higher production usually lead to less biodiversity. This is because the higher the production will often reach the wider areas that are more tightly packaged and the intensive use of chemical pesticides. However, this is not the case of apple orchards according to research:

"Organic gardens, as expected, have a higher biodiversity, which means that they have more research and predatory insects, but more apple production does not prevent biodiversity," said Peter Habak.
