According to KWS product development John Miles savings in PGRs due to Parkin’s stem stiffness could equate to £14/ha, but the cost-benefits of its early harvest potential could be significantly more.
“On a larger farm, or in certain locations, having a variety that is early maturing is incredibly important as it allows growers to protect income from the crop by spreading harvest workload and getting the grain safely in the shed.
“Based on the RL figures, Parkin has a treated yield of 102% - which isn’t too shabby - but I honestly believe some growers are now willing to trade slightly on yield because early maturity is just so valuable.
“A July harvest date is not impossible with Parkin and with a combine covering 20ha at 11.4t/ha that equals 228 tonnes of wheat harvested in a day worth £36,480 at £160/t.
“With a larger combine covering 35ha at11.4t/ha that’s almost 400 tonnes of wheat harvested in a single day worth £63,480 – and that’s before the main harvest has even started.”
Height and stiffness were the stand-out features behind the decision to choose KWS Parkin for drilling last year, says Bedfordshire Woburn Farms’ farm manager William Haupt.
“Risk management is becoming increasingly important to us plus we have two combines here and are keen to find a variety to help us spread the workload during the busy harvest season. Parkin’s early harvest could be really useful for us,” he explains.
“A mix of Group 1 and Group 4 wheats are grown on the farm and we decided we should drill 13.6ha of Parkin last autumn to see how it would perform as a first wheat. The options were to sell it either as a barn-filler or as seed for COFCO.”
The crop was drilled at a seed rate of 375 seeds/ m² and although it’s suited for the earlier end of the sowing window, weather constraints meant William didn’t get it into the soil until 21 Oct. However, that hasn’t affected performance, he says.
“Parkin is looking like it will be a good performer for us despite all the problems of the 2019/20 growing season.
“It’s emerged very evenly, matching the performance of its neighbour, Skyfall, and has looked good throughout the growing season. I was so pleased with it, I actually entered the crop into the ADAS yield enhancement network (YEN), so that should help give us a clear picture of what it is capable of.”
