SKRIPSI PENGARUH KADAR TRIACONTANOL PADA BERBAGAI JARAK TANAM TERHADAP HASIL TANAMAN LOBAK (Raphanus sativus L.)
ABSTRACT
The research was conducted from Novumber until Decem ber 1988, in Ngadipuro Village, Dukun District and Magelang Degunay. The objective of this research was to study the influence of trissentanal concentration and plant spacing on yield of radish (Japhanus matiyag.)
A split plot droign that waa arranged in randomized complete block design was uned in the field. The main plot consisted of plant spacing at 10 cm x 30 cm (J1), 15 cm x 30 cm (12), 20 cm x 30 cm (J) and the sub plot consisted of triscontanol concentrations at 0,00 ppm (K), 0,50 ppm (X1), 0,75 ppm (K2), 1,00 ppm (Kg). Every treatments was replicated a timee.
The results showed that plant speeing significantly affected the lenght of fleshy roots, circunference of Fleshy roots and very significantly affected the height of plant, number of leaves, weight of fleshy roots, freat weight of plant. Whereas triacontanol concentrations were not significantly affected the height of plant and number of leaven but very significantly affected the lenght of fleshy roots, circunference of fleshy roots, weight of flashy roots and fresh weight of plant.
Thare vare interactions between triscontanol concon- tration and plant apecing on fresh weight of plant. The highest yield at 65,61 ton per hectar sas reched by conti nation of plant spacing at 15 un 30 (1) and triacon- tanol concentration at 0,75 ppm (2)
