Introduction: Peanut (Arachis hypogaea L.) is among the top four most commercially important oilseed crops in the world. The objective of this research was to evaluate the agronomic response of this crop at different planting densities. Materials and methods: The experiment was conducted at the “Elpidio Sosa” Farm, Sagua La Grande municipality, Villa Clara province, Cuba. A randomized block design was used with one peanut cultivar (Cascajal rosado) and four planting densities (13.3; 11.1; 9.5; 8.3 plants m−2) in three replicates. Results: The results showed that the lowest planting density increased the values of the yield components: number of fruits and seeds per plant, weight of fruits and seeds per plant and biological yield, while at the highest planting density the yield of fruits, seeds and harvest index increased significantly. Discussion: These findings demonstrate that optimizing planting density is an important agricultural practice for exploiting the full yield potential and achieving a continuous increase in peanut production without increasing input use. Conclusions: A positive influence of higher planting density (13.3 plants m-2) on fruit and seed yields, 100-fruit and 100-seed weights, biological yield, and harvest index is evident.
