Aims

To study the effect of nitrogen (N) and phosphorus (P) application separately and in combination on the growth and yield of faba bean.

This experiment aimed to study the effect of nitrogen (N) and phosphorus (P) application separately and in combination on the growth and yield of faba bean. A small amount of N at sowing might improve yield through faster establishment and groundcover. There is also little local data available on faba bean response to additional P.

Key messages
  • Adding phosphorus (P) did not significantly increase yield or seed weight in the varieties PBA WardaA and PBA NasmaA.
  • PBA NasmaA produced greater yield and seed size than PBA WardaA.

Conclusions:

In this experiment, additional P did not increase yield, however, on a lower P site, a positive response to P might occur. The reduction in yield caused by adding N might be due to reduced nodulation in N-treated plots, although nodulation was not measured in this trial. The greater yield and seed size of PBA NasmaA compared with PBA WardaA supports other experimental data.

Fertiliser

Fertiliser treatments were applied immediately pre-sowing and seed was sown offset from fertiliser rows by 5 cm.

0, 5, 10 and 20 kg P/ha applied as triple superphosphate

0 and 10 kg N/ha applied as urea

Herbicide

Post-sowing/pre-emergent Terbyne® 1 kg/ha (terbuthylazine 750 g/kg) 

Post-sowing/pre-emergence: Terbyne® 1 kg/ha (terbuthylazine 750 g/kg) applied on 5 May Post-emergence: clethodim 500 mL/ha (clethodim 240 mL/L) applied 

Insecticide

Insect pressure was low and no insecticides were used.

Fungicide

Targeting rust (Uromyces vicia-fabae), and chocolate spot (Botrytis fabae and B.cinerea):

• Dithane™ @ 2 kg/ha (mancozeb 750 g/kg) applied on 4 July

• Dithane™ @ 1 kg/ha (mancozeb 750 g/kg) applied on 15 July

• Unite® 720 @ 1.5 L/ha (chlorothalonil 720 g/L) applied on 2 August

• Spin flo® @ 500 mL/ha (carbendazim 500 g/L) applied on 2 September

 

Other trial notes

RESULTS:

Establishment

Faba bean establishment of 19 plants/m2 was achieved, close to the target (20 plants/m2 ) and there were no significant (P<0.05) differences in establishment due to N, P or variety.

Reflectance and dry matter

No significant differences (P<0.05) in reflectance or biomass due to N, P or variety occurred, indicating that plant growth was not influenced by the treatments applied.

Grain yield and seed weight

Overall, PBA NasmaA gave significantly higher (P<0.05) yield and seed size than PBA WardaA  and N application unexpectedly reduced yield, with zero N plots yielding significantly (P<0.05) more (3.6 t/ha) compared with plus N plots (3.2 t/ha). Overall, adding P made no significant difference to yield , although there was a trend to higher yield with the highest (40 kg/ha) P application
