Durum Wheat Trials: Influence of faba bean stubble cultivation on durum yield and profitability (Finley) locations
Aims

To evaluate the influence of top work cultivation in faba bean stubble (using a speed till cultivator) on following crop durum yield and profitability.

Key messages

• There were no significant advantage in grain yield of durum following the cultivation of faba bean stubble from the year previous, however cultivation did result in significantly higher grain proteins where faba bean stubble were incorporated.
• Prior to this trial area being established in durum it grew four different plant populations of faba beans in 2020.
• In the previous year higher seed rates of faba beans led to higher plant populations and higher NDVI measurements but did not result in higher yield (range 16 – 23 plants/m2).
• With the following durum crop there was no significant effect of the different faba bean populations on durum wheat yields.
• Speed tilling to incorporate faba bean stubble in autumn 2021 (resulted in a trend to slightly lower plant establishment of 135 plants/m2 of durum compared to 144 plants/m2 where the residues were left on the surface and the durum was direct drilled into a firm seedbed.
• NDVI measurements taken in the durum at early tillering (GS21) showed a higher reading for the plots where the stubble was incorporated, however this may have been due to stubble interfering with the reflectance measurements. By stem elongation and crop ground cover the differences in NDVI had dissipated.
• There were no differences in dry matter recorded at flowering at a result of cultivating the previous years faba stubbles (not shown).
• Incorporating the faba residues resulted in significantly higher grain protein (15.5%) than where the durum crop was direct drilled plots (14.9%).
• There was a trend to lower grain protein at higher plant populations of the previous faba bean crop when the durum was direct drilled, although this was not statistically significant.
