Growth and production of Cichorium intybus in the second regrowth with different planting densities in Yogyakarta, Indonesia

Abstract

This study was aimed to evaluate the growth and production of Cichorium intybus in the second regrowth with different planting densities in Yogyakarta, Indonesia. Cichorium intybus were cultivated by spreading the seeds on a 1x1.5 m plots with different planting density as treatments: 2 g/m2, 3 g/m2, and 4 g/m2 – then named as D1, D2, and D3 groups respectively. Each treatment had 3 replications. Fertilization was performed once, on the day-15. The plant’s height and length were observed weekly for 30 days. Cichorium intybus were defoliated 5 cm above the soil surface on the day-28. Variables observed on this study include plant’s height and length, number of leaves, leaf width, number pf plants, dry and organic matter production. All data were evaluated by using one-way analysis of variance on the SPSS. Significant differences among groups were then subjected to further analysis – Duncan’s New Multiple Range Test. Different planting densities significantly alter number of plants, dry matter production, and organic matter production (P<0.05). The group with highest planting density has higher number of plants (198.33 ± 22.50) compared to D1 and D2 groups (108.66 ± 6.50 and 155.66 ± 8.02). Meanwhile, Cichorium intybus on D1 group had higher plant height (37.5 ± 0.6 cm) compared to D2 and D3 groups (31.77 ± 1.18 and 31.49 ± 0.92 cm). Based on this study, the Cichorium planted on 4 g/m2 of density results in highest production.
