SKRIPSI UJI UMUR BIBIT DAN DOSIS PUPUK UREA TERHADAP HASIL TANAMAN KUBIS BUNGA (Brassica oleracea)
ABSTRACT
An experimental research entitles Test of Seeding Age and Urea Fertilizer Dose on Yield of Cauli flower (Brassica oleracea) had been conducted since August 19, 2002 till October 19, 2002. The experiment was done in Bumirejo Village, District of Mungkid, Magelang Regency, Central Java Province. The soil type is Latosol with pH of 6.0 and the altitude is about 320 m.
The research uses factorial experiment in randomized completely design with four replicates. The first factor is age of seeding : 10, 20 and 30 days. The second factor is dose of Urea: 0; 0.5; 1; 1.5 and 2 grams per plant.
The results of the experiment show that:
1. Seeding age and dose of Urea enchance flower give significant effect on all observed parameters.
2. Seeding age of 30 days is better, though there is a tendency younger seedings grow vigorously.
3. Increasing dose of Urea up to 2 grams per plant still show a linear increase in plant height and weight of flower.
4. Increasing dose of Urea on each seeding age have significant effects observed parameters, except shoot length and number of leaves.
