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 Plant Stand Assessor

Using Row Length Method

Number of Plants Per Row

Count the number of plants along the same length of row indicated above in at least 3 areas

Add Area

Calculate Soybean Population

Soybean Population
- plants / ac

Plant Population

High: (>160,000 plants/ac)

Beyond the recommended plant stand, disease pressure may be increased

Good: (140-160,000 plants/ac)

Within the recommended range

Adequate: (120-140,000 plants/ac)

Within 5% of the recommended range

Low: (80-120,000 plants/ac)

Risk of yield loss

Very Low: (60-80,000 plants/ac)

High risk of yield loss, particular attention to weed control and pod height important

Plant population and yield information is based on final research results from Mohr et al. 2014. The effect of actual plant stand on relative yield of soybean was determined based on13 site years of data in Manitoba from 2011-2013.
