In the world of giant fruit and vegetable growing, the record for the heaviest pear belongs to JA Aichi Toyota Nashi Bukai, a group of farmers from Toyota, Aichi in Japan. On 11 November 2011, they presented a pear that weighed an impressive 2.948 kg (6 lb 8 oz) at the JA Aichi Toyota main office. The pear was an atago pear, the largest variety in Japan, originating from the Okayama prefecture.
The JA Aichi Toyota Nashi Bukai growers are no strangers to producing giant fruit. In fact, they are renowned for their skill in growing oversized nashi pears, a type of Asian pear. The group was formed in 1988 to promote local agriculture and share knowledge and techniques among farmers in the Toyota area.
To achieve such impressive results, the JA Aichi Toyota Nashi Bukai farmers use a range of techniques to encourage growth and produce healthy, robust fruit. These techniques include pruning, fertilizing, and carefully controlling the temperature and humidity in their greenhouses. They also use specialized nutrient solutions to ensure their plants have all the necessary nutrients to grow to their full potential.
