Responses of four varieties of carrot plant (Daucus carota L.) grown in medium latitude to different dosages of fertilization

Abstract

A study was conducted to investigate the effect of different rates of NPK fertilization on growth and yield of carrot plants in medium latitude. The experiment was undertaken in Setiling Village, Central Lombok (at ca. 650 m amsl) and arranged according to a RCBD two factors: variety (v) and dosages of NPK fertilization (n). The first factor were four carrot varieties: Gundaling (v1), Kirana (v2), New Nantes (v3) and New Kuroda (v4), while the second factor were four dosages of NPK fertilization: 50 kg/ha (r1), 100 kg/ha (r2), 200 kg/ha (r3) and 400 kg/ha (r4). The results showed that there was no interaction between carrot varieties and rate of NPK fertilization on influencing growth and yield of carrot in medium latitude. However, growth and yield of carrot in medium latitude were significantly influenced by variety and rate of NPK fertilization, as shown by differences in the ratio of above and below ground biomass, tap-root weight, tap-root diameter and the ratio between cortex and stele. Accordingly the suitable variety for cultivation in the medium latitude was Gundaling variety (v1), with a higher growth and yield were obtained by NPK fertilization at rate of 200 kg/ha (n3).

Pengaruh Berbagai Jarak Tanam Terhadap Hasil dan Mutu Umbi Tanaman Wortel (Daucus carota L.) di Dataran Rendah

“…Sementara itu, pertambahan jumlah penduduk dan peningkatan kebutuhan masyarakat menyebabkan terjadinya alih fungsi lahan menjadi fungsi lain yaitu sarana umum (jalan, tempat ibadah, sekolah dan sarana kesehatan), kebutuhan parawisata serta rumah sehingga luas lahan pertanian menurun. Beberapa hasil penelitian menunjukkan bahwa beberapa varietas tanaman wortel dapat ditanam di dataran medium dan dataran rendah, dengan teknologi budidaya yang sesuai (Firmasyah et al, 2016;Zawani et al, 2018;Amalia et al, 2019;Sidiq et al, 2020;Nikmatullah et al, 2021a;Nikmatullah et al, 2021b).…”
