Abstract

Wortel merupakan tanaman dataran tinggi yang banyak dibudidayakan dengan sistem budidaya monokultur dan tumpang sari. Ada juga beberapa yang ditanam di bawah / di antara tanaman tahunan. Hal ini mengakibatkan tanaman wortel harus dapat memanfaatkan cahaya, air dan nutrisi yang ada di bawah tanaman tahunan. Melihat fenomena tersebut, maka dilakukan penelitian yang bertujuan mendapatkan teknologi aplikasi dosis pupuk kandang ayam pada pertumbuhan dan hasil tanaman wortel di bawah naungan. Penelitian ini dilaksanakan pada bulan Januari hingga April 2003 di Desa Junggo Kota Batu, menggunakan rancangan percobaan Petak Terbagi. Terdapat 2 faktor perlakuan yaitu: (1) faktor pertama sebagai petak utama, berupa tingkat naungan terdiri dari 4 taraf: 0%, 20%, 40% dan 60%. Naxmgan yang digunakan berupa paranet plastik wama hitam; (2) faktor kedua sebagai anak petak, dosis pupuk kandang ayam dengan 3 taraf: 10, 20 dan 30 ton/ha. Sehingga diperoleh 12 kombinasi perlakuan yang diulang 3 kali. Hasil penelitian menunjukkan perlakuan tanpa naxmgan, pemberian pupuk kandang ayam 20 ton/ha meningkatkan pertumbuhan dan hasil, sedangkan pada tanaman yang dinaungi dengan pemberian pupuk kandang ayam menunjukkan tidak berpengaruh pada pertumbuhan maupun hasil wortel. Perlakuan naungan 20%, tanaman wortel dapat tumbuh baik, meskipun bobot umbi menurun 14% per m2, tetapi teijadi peningkatan kadar beta karoten umbi. Pemberian pupuk kandang ayam 10 ton/ha menunjukkan pertumbuhan dan hasil wortel tidak berbeda dengan pemberian dosis pupuk 20 dan 30 ton/ha.

English Abstract

Carrot is a highland plant that is mostly grown in monoculture and intercropping systems. There are even some were grown under / between perennial trees. However, this system causes the decline of light intensity, nutrient and water. In line with this phenomenon, a research was conducted to determine the influence of chicken manure and shading on carrot’s growth and yield. The research was conducted from January through April 2003 in Junggo Village in Batu using Split Plot Design. There were 2 treatment factors i.e: (1) as main plot, namely the percentage of shading consisting of 4 levels: 0%, 20%, 40% and 60%. The shading material used was black plastic net; (2) as sub plot, namely chicken manure dosage consisting of 3 levels: 10 tons/ha, 20 tons/ha and 30 tons/ha. The twelve treatment combinations obtained were replicated three times. The result showed that the treatment of 20 tons/ha chicken manure onto carrot grown with no shading increased the growth and yield. This treatment, however, did not show a significant difference in the growth and yield when applied to carrot grown with shading. The treatment of 20% shading, yielded a good plant growth although accompanied by the decrease in the fresh tuber weight by 14% and the increase in beta carotene content. The application of 10 tons/ha did not show difference in the growth and yield of carrot treated with 20 tons/ha and 30 tons/ha of chicken manure. 1
