Current and Recent Research

Faculty at the Rex E. Kirksey Agricultural Science Center at Tucumcari have several key projects under way. Our Annual Reports provide information for ongoing and recently completed projects as well as weather data for the previous five years and the long-term averages and records.

Extension publications and NMSU reports on some completed projects also have been published and are available at the websites shown below.

Most other research projects completed at the center have been published in external scientific literature and not through NMSU. Many of these can be made available as a pdf by email upon request to Look at the faculty CV's posted to our "Personnel/Staff" page to find a list of externally published articles by that faculty member.

New Mexico Crop Variety Test Reports

Current Projects

Jujube orchard: 36 varieties (Lauriault Hatch; initially funded for installation by USDA/NMDA Specialty Crops grant with Shengrui Yao)

Crop variety testing: Alfalfa, corn, cotton, corn and sorghum grain (separate tests), and sorghum forages (forage sorghum and sorghum x sudangrass as separate tests)(funded by company sponsorships)

Bindweed grazing project (off-station; Lauriault Hatch)

Canola grazing (partially funded by Sangu Angadi. Lauriault Hatch, and grazing fees to be assessed; pending more data collection based on 2019-2020 results)


Strip-till manure for grain sorghum production: This is a long-term project replanting the same plots each year (Darapuneni Hatch)

Opportune crops for dryland winter wheat systems during fallow (Darapuneni Hatch; on hold during COVID-19)

Summer and winter cover crops (AES competitive grant)

Guar fertility: With John Idowu (Sustainable Bio-Economy for Arid Regions grant)

Alfalfa fertility (off-station; Sirius Minerals)


Alfalfa water source evaluation (Lauriault Hatch; hopefully to generate preliminary data for someone to use for a major grant)

Summer annual grass and legume mixtures for forage (actually two projects, one of which now has a Darapuneni WTAMU graduate student component) (Lauriault Hatch and WTAMU collaborator funding)

Tepary bean forage: Regional collaboration led by Rich Pratt (Lauriault Hatch)

Non-destructive measurements to estimate hemp biomass component yield (off-station; Lauriault Hatch; waiting to collect first-year final weights after seed separation from 2019 crop; will not be repeated in 2020, but maybe 2021, if the grower plants again)
