V letu 2019 smo spremljali vpliv različne gostote sajenja in različnih vrst potaknjencev na razrast in količino poganjkov poprove mete (Mentha × piperita L.). Pripravili smo potaknjence (vršne in bazalne), ki smo jih kasneje posadili v poskusno gredo v štirih različnih gostotah, 20, 16, 12 in 8 rastlin/m2. Med poskusom smo v različnih terminih izvedli 5 rezi pridelka. V sklopu rezultatov smo obravnavali število poganjkov, dolžino poganjkov, povprečno maso svežega poganjka, delež vode v poganjkih, pridelek sveže mase in pridelek sušine. Kot smo pričakovali, je večja gostota sajenja, v našem primeru 20 rastlin/m2, pripomogla k pridobitvi večjega pridelka sveže mase in sušine poprove mete. Glede na dolžino in maso poganjkov smo ugotovili, da so gostote saditve 12 rastlin/m2 in 16 rastlin/m2 v povprečju pokazale boljše rezultate kot preostali dve gostoti saditve. Vrsta potaknjenca (bazalni ali vršni) na pridelavo ni imela vpliva, saj so bili na koncu poskusa rezultati pri obeh vrstah potaknjencev, kot smo tudi predvidevali, podobni. 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. |
