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:
- 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.
- 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.
- 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.
- 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).
