SKRIPSI PENGARUH JARAK TANAM DAN DOSIS PUPUK NPK TERHADAP PERTUMBUHAN DAN HASIL TANAMAN LOBAK (Raphanus sativus)
ABSTRACT
The experiment about of the effect of plant distance and NPK fertilizer dose on growth of radish (Raphanus sativus), have been done since January 4", until March 5", 2002 in Paponan Village, Kledung District, Temanggung Regency. The altitude is 815 m and the soil type is latosol.
The method of experiment is factorial (3x4) with completely randomized design and three replications. The first factors, plant distance: 20 x 25 cm, 20 x 35 cm and 20 x 45 cm. The second factors, NPK fertilizer dose: 0; 2,8; 4,2 and 5,6 g per plant.
The result of analysis shows that plant distance treatment on radish plantation is increasing number of1eaves and weight of tuber per plant. The increasing dose of NPK fertilizer may increase all observed parameters. Increasing dose ofNPK fertilizer on distance of planting give the different tuber weight per plant. At 20 x 35 cm plant distance with the added ofNPK fertilizer dosage 4,2 g per plant give 384,75 g tuber's weight per plant that this is the highest result of radish tuber.
