PENGARUH PEMBERIAN PUPUK ORGANIK DAN ANORGANIK TERHADAP PERTUMBUHAN, HASIL DAN KUALIT AS BAWANG DAUN = THE EFFECTS OF SEVERAL ORGANC AND INORGANIC FERTILIZERS ON THE GROWTH, YIELD AND QUALITY OF BUNCHING ONION

The aims of this research was to study the effects of organic and inorganic fertilizers on growth, yield and quality of bunching onion. This research was conducted at Ngestiharjo, Kasihan, Bantul, Yogyakarta from February until June 2006. The research was arranged in Randomized Complete Design with two factors and three replications. The first factor was kinds of organic fertilizers, consisted of wthout fertilizer application, azolla, punik (cow manure compos), cow manure fertilizer, azolla + inorganic, punik (cow manure compos) + inorganic, cow manure fertilizer + inorganic. The second factor was kinds of bunching onion, consisted of Super and Muntilan. The results showed effects of fertilizers increased plant growth i.e. length of leaves, leaves area, net assimilation rate, crop growth rate, shoot root ratio, and crop dry v.eight. The fertilizers could increase yield and its quality i.e. diameter of stem, leave green scale, and crop fresh v.eight, on the other hand the fertilizer decreased in the percent of damage and glucose reduction content. Kinds of organic fertilizers was no significant. Organik and inorganic fertilizers was no significant. Two bunching onion potential in production
