Porchester Farms, from the Highclere Estate scooped several awards for seeds at this year's show.
A total 86 bags of seed and beans were lined up in the Harvest Centre for judge Iain Hamilton to cast a critical eye over, from wheat and barley, to oats.
Discerning factors included the overall appearance, whether the seeds had been well threshed, the husk removed fully and any insect damage, for example holes left in beans by the bruchid beetle larvae.
Porchester Farms proved the overall winner for the hay classes and also best of the corn entries. Yattendon Estates was the overall winner of the malting barley category and also for beans.
Diversifying out of farming has proved a winner for Ramsbury farmers Darren Goulding and his wife Joanna of Stockclose Farm, a 25,000 acre business, who use the barley they grow to make beer and vodka and who have also forged links with Ramsbury beekeepers to produce Ramsbury Honeybee Nectar Beer.
The enterprising couple are also about to open a smokehouse offering smoked venison, pheasant, partridge, pigeon, trout and duck.
Attracting a crowd in the doorway with his huge apple press was Richard Paget, of Savernake Forest, situated between Hungerford and Marlborough, who will have pressed two tonnes of apples by the time the show draws to a close, and who provides a local, community apple juicing service.
"I'm the local apple man," said Mr Paget.
"90 per cent of all apples in private gardens fall and go to waste," he said.
A crowd also gathered to view some stunning photographs taken by farmers in a competition, with first prize for the farming selfie won by Harriet Bunning, in her mid' 20's of Devon, for a photo taken on her farm beside a cow sticking out its tongue.
Farmer, Harry Yorke, of Froxfield, also won a prize for his harvest selfie photograph.
