In 2019, we monitored the effect of different planting densities and different types of cuttings on the growth and quantity of peppermint shoots (Mentha × piperita L.). We prepared cuttings (head and stem cuttings) that were later planted in an experimental field at four different densities (20, 16, 12, and 8 plants/m2). During the experiment, we conducted 5 harvest cuts at different time points. Results included number of mint shoots, shoot length, average fresh shoot weight, water content in shoots, fresh mass yield, and dry mass yield. As expected, a higher planting density, in our case 20 plants/m2, contributed to obtain a higher yield of fresh mass and dry mass of peppermint. Considering the length and mass of the shoots, we found that planting densities of 12 plants/m2 and 16 plants/m2 showed on average better results than the remaining two planting densities. The type of cuttings (stem or head cuttings) had no effect on production, as at the end of the experiment, the results of both types of cuttings were similar, as we predicted.
