Dosage, Frequency, Baby KailanAbstract
Baby Kailan has good market prospects, so it would be good if it were developed. However, kailan production is decreasing due to low soil productivity. One way to overcome this is using cow urine POC. This study aims to test whether there is an interaction between the dose and frequency of administration of cow urine POC on the growth and results of baby kailan. This research used a factorial Completely Randomized Design (CRD), which was repeated three times. The first factor is dose, with three treatment levels: 30 ml/polybag (D1), 60 ml/polybag (D2), and 90 ml/polybag (D3). The second factor is the frequency of administration of cow urine POC, with three levels of treatment: 1 administration (F1), two administrations (F2), and three administrations (F3). Parameters observed included plant height, number of leaves, leaf area, stem diameter, plant wet weight, plant dry weight, and root dry weight. The data collected was then analyzed using factorial analysis of variance, and if there were significant differences, the Honestly Significant Difference (BNJ) test was continued at the 5% level. The study's final results showed no significant interaction between the dose and frequency of administration of cow urine POC on all observed parameters. However, the dose treatment significantly affected the number of leaves at 30 DAP, especially in treatment D2 (60 ml dose/polybag). In addition, treatment doses of D1 (dose 30 ml/polybag) and D2 (dose 60 ml/polybag) significantly affected root dry weight. There was also a significant difference in the frequency of administration of cow urine POC on root dry weight, with the highest root dry weight occurring in the F3 treatment (administration frequency three times).
Baby Kailan memiliki prospek pasar yang bagus sehingga baik jika dikembangkan. Namun produksi kailan semakin menurun, hal ini disebabkan oleh produktifitas tanah yang rendah. Salah satu upaya penanggulangan yaitu dengan menggunakan POC urine sapi. Penelitian memiliki tujuan untuk mengetahui interaksi dosis terhadap aplikasi frekuensi pemberian Pupuk Organik cair Ubrine sapi terhadap pertumbuhan dan hasil baby kailan. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) faktorial yang diulang sebanyak 3 kali. Faktor pertama adalah dosis, dengan tiga tingkat perlakuan: 30 ml/polybag (D1), 60 ml/polybag (D2), dan 90 ml/polybag (D3). Faktor kedua adalah frekuensi pemberian POC urine sapi, dengan tiga tingkat perlakuan: 1 kali pemberian (F1), 2 kali pemberian (F2), dan 3 kali pemberian (F3). Parameter yang diamati meliputi tinggi tanaman, jumlah daun, luas daun, diameter batang, berat basah tanaman, berat kering tanaman, dan berat kering akar. Data yang dikumpulkan kemudian dianalisis menggunakan analisis ragam faktorial, dan jika terdapat perbedaan yang signifikan, dilanjutkan dengan uji Beda Nyata Jujur (BNJ) pada taraf 5%. Hasil akhir penelitian menunjukkan bahwa tidak terjadi interaksi signifikan antara dosis dan frekuensi pemberian POC urine sapi terhadap semua parameter pengamatan. Namun, perlakuan dosis menunjukkan pengaruh signifikan terhadap jumlah daun pada umur 30 HST, khususnya pada perlakuan D2 (Dosis 60 ml/polybag). Selain itu, perlakuan dosis D1 (Dosis 30 ml/polybag) dan 2 (Dosis 60 ml/polybag) secara signifikan mempengaruhi berat kering akar. Terdapat perbedaan signifikan juga pada perlakuan frekuensi pemberian POC urine sapi terhadap berat kering akar, dengan berat kering akar tertinggi terjadi pada perlakuan F3 (frekuensi pemberian 3 kali).
