SKRIPSI PENGARUH MACAM PUPUK ORGANIK DAN VARITAS TERHADAP HASIL TANAMAN KOBIS (Brassica oleraceae, L.)
ABSTRACT
The experiment about the effect of kinds of organic fertilizer and variety on yield of cabbage plant (Brassica oleraceae, L.), had been carried out since March until June 1999 at Ngadipuro, Dukun Sub District, Magelang District, Central Java. The soil is latosol with pH 6,0 and the altitude 500 meters.

Litter reduces on age of crop formation, but increases weight of crop, fresh weight of straw, and dry weight of straw. Litter with variety TOTO 101 tends to have the highest yield on weight of crop that is 2066,93 gram and organic fertilizer of compost with variety King tends to have the lowest yield on weight of crop that is 1316,96 g.
