Application of Organic Fertilizer From Rabbit and Cattle Farm Waste on Shallots Growth and Yield (Allium cepa var. ascalonicum L.)

Abstract

Shallots are one of the vegetable commodities that have important meaning for society in terms of their economic value and nutritional content. Shallots are commonly consumed as a spice to add flavor to dishes. In general, shallots contain nutrients and active compounds that have preventive and curative functions when used as herbal medicine. Various methods of cultivating shallots are used to increase yields both in quantity and quality, including applying various organic fertilizers such as those made from rabbit and cattle farming waste. The aim of this research was to determine the effectiveness of organic fertilizer from rabbit farm waste combined with organic fertilizer made from cattle farm waste on the growth and yield of shallots. The research was carried out using experimental methods, using a Randomized Block Design with a 2x3 factorial pattern with 3 replications. There are two factors studied, namely the first factor, type of fertilizer (P), which consists of 2 levels (types) of fertilizer, namely: R (Rabbit Farm Waste Fertilizer); and C (Cattle Farm Waste Fertilizer). Meanwhile, the second factor is the dose (D) of each type of fertilizer which consists of 3 levels, namely: D1 (10 tons/ha); D2 (20 tons/ha); and D3 (30 tons/ha). The results of this study indicate that the interaction between the two factors has no significant effect (P≥0.05) on all observed variables. The effectiveness of the treatment with doses of rabbit manure also had no significant effect on all parameters observed, however there was a tendency for a dose of 30 tons/ha to produce the highest oven dry weight of tubers per hill, namely 29.503 g. The treatment of giving a dose of cow manure of 30 tons/ha gave the highest oven dry weight of tubers per hill, namely 27.003 g. The interaction between the dose of rabbit manure and cow manure (RxC), the treatment dose of rabbit manure (R) and the treatment dose of cow manure (C) had no significant effect (P≥0.05) on all observed variables.
