A crop of blue peas has yielded a record 7.48 tonnes/hectare at 15.04 per cent moisture.
Harvested on September 7 at Worlaby Farms in Lincolnshire, grower Tim Lamyman says he is delighted with both the yields and quality to come off this year’s pea crop.
“I am absolutely thrilled with the final performance of the peas as they have shown a consistency in biomass through the season - much more so than last year. In places the crop was six feet tall – and this has obviously translated into yield.”
LG Stallion was the field pea variety of choice, selected for its high yield potential and good standing ability.
This is the third year that Mr Lamyman has grown the variety, breaking the world record yield in 2017.
The peas follow a second wheat in the seven year rotation which also includes wheats, spring barley and oilseed rape.
“The field chosen for the crop is much like last year; a Grade 2 chalky loam which offers the potential for well-structured root systems, enabling easier nutrient uptake - which I believe is key to a high yielding crop,” says Mr Lamyman.
“As the spring was so dry, we adapted our cultivations for the peas through an intensive min-till approach which allowed us to create a more level seedbed.”
Before drilling, the field had two passes with a Lemken Terradisc and finished with a Vaderstad carrier (discs and crumble roller), and then it was rolled with Cambridge rollers the day after drilling.
The crop was drilled on April 9 using a Vaderstad Rapid, with the coulters set at a 4-inch row width.
The seed was treated with Wakil XL + GPA, with the aim of early downy mildew control from the Wakil XL and better root development, as well as plant establishment with the phosphite-based nutrient GPA.
Established plant populations were 85 plants/sq.m, he says.
Mr Lamyman believes that detailed and well-targeted crop nutrition is critical to his success.
“Leaf samples were taken at four different stages through the crop’s growth cycle in order to identify nutrient deficiencies, to which the relevant products were then applied as required.
“Foliar applications were similar to those used in 2018. An early insecticide [50 ml Hallmark] was applied for weevil damage. Just before flowering, 2 l/ha of ToPPit +1 l/ha of Rainbow Wave went on.
“In 2017 we had virus in the crop, and given the high aphid numbers this year we applied Aphox early.
“At flowering, the tank mix consisted of 280 g/ha Aphox, 1 l/ha X-Stress, 2 l/ha ToPPit, 0.5 kg/ha Signum and 0.5 l/ha CalFlux.
“Two weeks later, another spray containing 2 l/ha ToPPit, 0.5 l/ha CalFlux, 1 l/ha X-Stress, as well as 50 ml/ha Hallmark went on.
“As harvest approached and the weather was very changeable, we decided to apply some Reglone on August 23, in case of a delay to harvest, and that helped.”
