In-Progress

In recent years, many Manitoba farmers have turned to edible beans and soybeans as high-value cash crops that also impart diversity and nitrogen-fixing capacity to annual crop rotations.  The potential for salinity in Manitoba fields is a concern for an increasing number of Manitoba farmers.  Edible beans are among the most salt-sensitive crops and their shallow-rooted, low water-use nature escalates this problem.  Salt deposits on the soil surface along roadways or in low spots give evidence of salinity, as do heavy infestations of salt-tolerant weeds.  An assessment of the extent, severity and temporal dynamics of soil salinity in select dry bean fields in southern Manitoba, as well as an evaluation of wide- vs. narrow-row beans (in terms of water use and salinity development) will provide information and recommendations allowing for the maintenance of this high-value, export crop without compromising our rich, yet degradable land resource.  Screening existing edible cultivars may reveal varieties that are better able to withstand higher salt concentrations, thereby increasing field options for farmers considering bean production.

The Manitoba Pulse Growers Association is a funding partner in this project.  Postgraduate scholarship funding has been provided by the Natural Sciences and Engineering Research Council and Agricore United.
