Interpretive Summary: Dual use crops allow producers to maximize limited resources. This study evaluated the late season (>15 weeks after planting) forage production of four peanut market types at Clovis, NM and El Reno, OK. The results of this study show that peanuts can produce, on average, 2 tons of forage per acre with a relative feed value of 107 to 155. This study indicates that harvesting late season biomass may be an option to maximize limited resources.

Technical Abstract: Dual use crops are becoming popular as resources like land and water availability become scarcer. Peanuts are an important food crop worldwide that can also be used as forage or hay. Replicated trials evaluated the late season (=15 weeks after planting) forage yield and quality (acid detergent fiber, carbon content, crude protein, invitro true digestibility, neutral detergent fiber, nitrogen content, and relative feed value) of four market types near Clovis, NM and El Reno, OK in 2019 and 2020. Statistical analyses (p = 0.05) showed all traits were affected by the interaction between market type and growing environment. Overall, forage yields for all market types ranged from 2.7 to 6.5 Mgha-1 with relative feed values of 107 to 155. The location average across sites was 4.45 Mgha-1 with relative feed value of 132. This study indicates harvesting late-season biomass of peanuts for hay may be an option to increase productivity for producers. However, both market type and environmental factors, such as rainfall/irrigation, play important roles in productivity and forage quality.
