Pulse Research Webinar - Fertility Management to Optimize Yield & Protein in Field Peas

April 07, 2021

12:00 PM - 1:00 PM

Please join us for this pulse research webinar where Chris Holzapfel, Research Manager with the Indian Head Agricultural Research Foundation shares results from his recently completed research project: Enhanced Fertilizer Management for Optimizing Yield and Protein in Field Pea.

In this webinar, attendees will learn:

1. Field peas responded well and reasonably consistently to phosphorus fertilizer application in low P soils, with average yield increases of up to 13% and an optimal rate of approximately 36 lb P2O5/ac for both yield and profit.
2. Field pea responses to sulfur were both rare and difficult to predict using soil tests. Applying a small amount of S may be advisable in fields where deficiencies have been observed in the past and to help maintain soil fertility; however, S availability is unlikely to be an important factor limiting field pea yields for most Saskatchewan soils.
3. Normal application rates of P and S fertilizer combined with adequate inoculation will likely provide all the N that field peas require. Extra N fertilizer was as likely to have a negative impact on yield and protein as it was to be beneficial under normal circumstances.
4. Overall, fertilizer management does not appear to have much impact on protein development in field peas; however, in general, the practices that were most likely to optimize yield also tended to result in the highest protein levels (i.e., adequate P fertilization).
