SKRIPSI PENGARUH PENGGUNAAN MACAM PUPUK ORGANIK DAN FORMULASI UREA TERHADAP HASIL TANAMAN KURIS (Brassica oleracea var. capitata L.)
ABSTRACT
The experiment of effect of manure and urea formulation to the yield of cabbage was carried out from 22 August until 26 October 1994, at Pucang village, Secang, Magelang. The soil is Latosol, the pH 6,41 with an altitude of 386 m.
The purpose is know the effect of manure in combination with urea formulation to the yield of cabbage of K-K Cross variety.
The experiment was arranged with Randomized Completely Block Design (RCBD), arranged in Factorial, with two factors and three replications.
Factor I : Kinds of manure (P) consist of 5 levels, they
are:
Po : Formyard manure of goat
P1 : Compost INRA
P2 : Compost azolla
P3: Green manure of groundnut leaves
P4 : Organic Soil Treatment
Faktor II: Urea formulation (U) consist of levels, they
are :
U0 : urea prill formulation
U 1: urea brikket formulation 1
The result showed that:
1. The manure gave a high significant effect for all obser- vation parameters.
2. Urea formulation gave significant effect only on width of leaves.
3. Interaction of effect only found on width of leaves and stem diametre.
