Field experiment reveals intercropping sunnhemp with forage sorghum maintains dry matter and enhances nutritive value, indicating a viable method to boost livestock feed quality.

Key Points

Evaluate the growth potential, optimal seeding ratios, and harvest frequency of sunnhemp intercropped with forage sorghum to enhance forage crude protein while maintaining dry matter production.
Conducted a two-year agronomic field experiment under drip irrigation in Canyon, TX, USA during 2020 and 2021.
Evaluated factorial combinations of sunnhemp at three seeding rates (16.8, 33.6, and 50.4 kg ha⁻¹) and forage sorghum at four seeding rates (0, 2.8, 5.6, and 11.2 kg ha⁻¹).
Measured midseason yield, full-season yield, regrowth biomass, and overall forage nutritional quality across harvest regimes.
Sunnhemp–forage sorghum intercrops achieved dry matter yields comparable to sole-crop forage sorghum when adequate growing-season heat units accumulated.
Implementing a two-cut system with a midseason harvest and regrowth collection produced forage with higher nutritive value than single full-season harvesting.
