Active Prime, Active Build and Active Grain fill crop response in wheat

By Dumbleyung 2020, Dumbleyung Nutrition 2020

Objective

To evaluate the efficacy of Active PRIME, Active BUILD and Active Grain FILL on seed germination, vigour, disease rating, grain yield and grain protein content in wheat.

Background

The trial was sown on the 2nd of June 2020 in Dumbleyung, WA where the GSR was 240mm. The first major rain event after seeding (20mm) occurred on the 18th of June. Foliar treatments of Active Build were applied on the 30th of July. Active Grain fill was applied at ear emergence prior to flowering Z55 (ear half emerged).

Key Findings

  • No significant yield difference between treatments.
  • Higher emergence numbers in plots treated with active prime seed treatment.
  • Active prime 4ml/kg achieved 15% & 18% increase in crop emergence numbers for both treatments respectively.
  • Treatment differences were not visible past tillering.
  • No significant difference between Active Prime 4ml/kg seed treatments stand alone and Active Prime 4ml/kg followed by Active build 2.5L/ha and Active Grainfill 2.5L/ha.
  • Higher plant density at emergence in Active Prime treated plots, translated into vigour observations later in the season. Wheat yields were lower than expected, around 2.5 t/ha, as a result of low growing season rainfall.
  • Soil pH 5-5.5 should have healthy soil microbial activity and nutrient availability. In this season responses were not significant.

Wheat Stimulant Trial

By Dumbleyung Nutrition 2020

Objectives

  1. To evaluate the efficacy of Active PRIME, Active BUILD and Active GrainFILL on seed germination, vigour,disease rating, grain yield and grain protein content in wheat.
  2. Evaluate the efficacy of Sabel-X seed treatment.
  3. Evaluate the efficacy of Bombardier applied in furrow and foliar.

Background

The trial was sown on the 2nd of June in Dumbleyung, WA, where the next major rain event recorded 20mm on the 18th of June. Seed treatments were applied to grain prior to seeding. Bombardier 2L/ha in furrow treatment went down with the flexi N and was placed 60mm below the seed. Seeding depth was 20mm. Foliar treatments were applied on the 30th of June.

Key Findings

  • Sable-X 1.2g/kg and Bombardier 2L/ha in furrow caused significantly greater crop emergence than the untreated control.
  • Visual vigour ratings 15DAAB saw an increase of 5% in plant vigour of Bombardier 2L/ha; fb Bombardier 2L/ha and Bombardier 4L/ha respectively.
  •  No significant difference in yield between treatments compared to the control.
  • Sabel-X achieved 15.8% higher yields than control on average.
  • Early emergence and vigour ratings did not translate into yield increases for both Bombardier treatments.
  • Plants response to the N decreased in low rainfall.
  • Wheat yields were lower than expected, around 2.5 t/ha, as a result of low growing season rainfall.

CSBP Phosphorus Response

By Dumbleyung 2020, Dumbleyung Nutrition 2020

CSBP, GRDC & DPIRD

Objective: To determine the responsiveness of wheat to phosphorus (P) fertiliser and the effectiveness of Agras compared to MAP.

Background: This trial is part of a GRDC project aimed at increasing profit from nitrogen (N), phosphorus (P) and potassium (K) fertiliser inputs. Cropping systems have evolved a lot over the last 20 years with the adoption of no-till, earlier seeding and rainfall has declined. In this project, there are 40 one-year P response trials being conducted on wheat over 4 years to determine whether P fertiliser requirements have changed. These trials will also be used to evaluate different soil sampling methods and alternative laboratory tests.
