Most spring barley planted in 24 hours

The most spring barley seed planted in 24 hours is 74,347 kg (163,907 lb) covering an area of 571.9 ha (1,431 acres) by an unmodified AGCO Challenger MT865 tractor pulling an 18.35 m (60 ft) wide Horsch seeder at a Agro-Soyuz farm in the Sinelnikovo region, Dniepropetrovsk, Ukraine from 23-24 April 2003.

At 500 horse power, the Challenger MT865 tractor is considered the world’s largest production tractor. The record was set on just two fields, one having runs up to 4.5 km (2.8 miles) long and the other up to 2.5 km (1.55 miles) long. The average work rate was 57.8 acres/hr (23.4 ha/hr).
The team behind the record hope that the crop of Prerea spring barley will yield 3.5-4 t/ha, compared with the average yield of 2.3 t/ha.
211 tonnes of fertiliser was used.
