Evaluation of Different Planting Densities in the Cultivation of Dianthus barbatus, Green Ball, and Kiwi Mellow Varieties. Cienc. Ing. Neogranad.

Carnation holds great importance in Colombian floriculture, with Dianthus barbatus, in its Kiwi Mellow and Green Ball varieties, being an alternative for sector growth due to the beauty it adds to floral arrangements. However, Colombian companies need to innovate and optimize resources to manage planting space effectively and improve productivity. Therefore, different planting densities and containers were evaluated for the mentioned varieties, using a completely randomized design with four treatments per variety (23 plants/m2, two containers per bed; 46 plants/ m2, two containers per bed; 27 plants/ m2, one container per bed; 54 plants/ m2 one container per bed), with four repetitions per treatment. The planting density of 54 plants/ m2 in one container per bed, for the Kiwi Mellow and Green Ball varieties, had a significant effect on productivity, increasing yields by 30% and 20%, respectively, compared to the common treatment in the area (planting density of 23 plants/ m2). The increased planting densities did not affect flower quality parameters or increase losses due to national quality. The Kiwi Mellow variety has an average of 3.16% more Soil Plant Analysis Development (SPAD) units than Green Ball. The best profitability in the cultivation of D. barbatus for the two evaluated varieties was achieved with a planting density of 54 plants/ m2, surpassing the zone treatment by 34% and 15%, respectively.
