Good news for growers! Lentils are still a good option for growers to consider in future cropping programs on medium to heavy textured soils. Trials in 2017 produced seed yields of 1.5t/ha or above.
This comes after the Department of Primary Industries and Regional Development conducted trials, with Grains Research and Development Corporation (GRDC) investment.
The results shows that sowing lentils to achieve 100-110 plants per square metre in mid-April resulted in profitable yields.
Department senior research officer Mark Seymour said ideal seeding rates were 45kg/ha for small seed types such as PBA Hurricane XT, 50kg/ha or medium sizes varieties, including PBA Bolt and 60kg/ha for PBA Jumbo2.
Trials were sown at Dongara, Wittenoom Hills, Kumarl north of Salmon Gums, Grass Patch and Gnowangerup in April and May.
But which lentil is the top gun? Mr Seymour said PBA Bolt was a consistent performer across all trial sites.
“PBA Bolt is the most popular lentil variety grown in WA, with alternative options of PBA Hurricane XT and PBA Jumbo2 ,” he said.
“The Grass Patch trial sown in mid-April was the highest yielding trial for PBA Bolt at 2.3t/ha, followed by 1.9t/ha at Wittenoom Hills.”
PBA Hurricane XT was shown to be noticeably slower growing than PBA Bolt and yield was equal to or lower than PBA Bolt. While PBA Jumbo2 has the best disease resistance of the varieties.
But, Mr Seymour says PBA Hurrican XT is the best available option if growers are concerned about sulfonylurea residues or if they're planning to use imazethapyr in-crop for increased weed control.
