Pengaruh Pupuk Kotoran Kambing Dan Pupuk Npk Terhadap Pertumbuhan Dan Produksi Tanaman Bawang Merah (Allium Ascalonicum L.)
ABSTRACT
Proper and appropriate fertilization is essential for successful shallot cultivation. The growth and yield of shallot (Allium ascalonicum L.) can be enhanced through the combined application of organic and inorganic fertilizers, specifically goat manure and NPK fertilizer. This study aimed to evaluate the interaction effects of goat manure and NPK fertilizer and to identify the optimal treatment for improving the growth and yield of shallot plants. The experiment was conducted using a Completely Randomized Design (CRD) with two factors, each replicated three times. Factor I: Goat manure dosage with three levels K0 = 0 t/ha, K1 = 10 t/ha, and K2 = 20 t/ha. Factor II: NPK fertilizer dosage with three levels N0 = 100 kg/ha, N1 = 150 kg/ha, and N2 = 200 kg/ha. The results showed that the interaction between goat manure and NPK fertilizer had no significant effect on any of the measured parameters. Goat manure significantly influenced plant height, harvest time, bulb diameter, and the number of bulbs per plant, with the best performance observed at a dose of 20 t/ha. NPK fertilizer significantly affected plant height, leaf number, bulb number, fresh bulb weight per clump, fresh bulb weight per square meter, and storable bulb weight per square meter. The optimal NPK fertilizer dosage was 200 kg/ha.
