About the MPSG Bean App

The Manitoba Pulse & Soybean Growers (MPSG) organization represents 3,800 farmers in Manitoba who grow soybeans, edible beans, peas and other pulses. MPSG’s mission is to provide research, production knowledge and market development support to Manitoba pulse and soybean farmers. This app is a production tool that delivers research results and resources directly into the hands of farmers and their agronomists, assisting them with production decisions.

The MPSG Bean App features six interactive tools. The Seeding Rate Calculator can be used to determine the economically optimum seeding rate for soybean. A soybean Plant Stand Assessor walks users through evaluating plant populations after seeding to see if their target plant stand has been reached. A soybean Growth Staging Guide provides a picture and description of each growth stage and can be used to ensure timely management decisions. The soybean Yield Estimator outlines the key parameters that contribute to grain yield, allowing users to estimate yield prior to harvest. The soybean Harvest Loss Assessor guides users in an exercise to quantify harvest losses at the header and behind the combine to identify settings that need adjustment. The White Mould Risk Assessment helps users understand the environment and management decisions affecting white mould development in edible beans.

MPSG does not validate results and takes no responsibility for the accuracy if these results. The MPSG Bean App was developed with assistance from MPSG Production Specialists. Funding for App developments was been provided in part by Growing Forward 2. For more information, visit www.manitobapulse.ca

Soybean Yield Estimator

Based on your information, this is a yield estimate and should be treated as an estimate only. The 5 and 10 year average soybean yield in Manitoba is 33 and 31 bu/ac, respectively.

Seeds Size

Enter the seed size according to your variety (found on seed tag label) and environmental conditions. If you expect larger seeds due to good growing conditions, decrease value to 2400 seeds/lb (larger seed). If you expect smaller seeds due to poor growing conditions, increase value to 3200 seeds/lb (smaller seed).

Seeds Per Pod

Average in Manitoba has been found to be 2.3. Reduce to 2.0 if growing season is stressful.

Soybean Plant at R-6

Soybean plant at R-6 (full seed): pods contain green seeds that fill the pod to capacity at one of the four uppermost nodes on a main stem.
