Shallots (Allium ascalonicum L.) is one of the most widely consumed horticultural commodities for human consumption as a mixture of cooking spices. One of the efforts to achieve optimal shallot yields is through the provision of organic matter. Utilization of chicken manure as an organic material used in fertilizing shallots can improve the physical and chemical properties of the soil. The application of chicken manure and inorganic fertilizers is expected to have a substantive effect on increasing the yield of shallots compared to the application of compound fertilizers. The purpose of this research is to increase the availability of organic matter and nutrients in the soil and to increase the yield of shallots on a field scale (wide). This research will be conducted from December 2020 to February 2021 at Pendem, Junrejo, Batu, East Java. The altitude is 550 masl and the soil type is Andosol, with air temperature 14o - 32o C. This research was carried out using a factorial randomized block design (RAK) with 2 factors and 3 replications. The first factor is chicken manure (K) consisting of 3 levels of treatment, namely: K0 = Chicken Manure 0 t ha-1, K1 = Chicken Manure 10 t ha-1 and K2 = Chicken Manure 20 t ha-1. While the second factor is inorganic fertilizer (nitrogen) which consists of 6 levels of treatment, namely: N1 = 120 kg ha-1, N2 = 160 kg ha-1, N3 = 200 kg ha-1, N4 = 240 kg ha-1 and N5 = 280 kg ha-1. Data analysis using analysis of variance (ANOVA) and testing using F table 5% level. If there is a significant effect, then it is continued with the smallest significant difference test (LSD). The results of this study showed that chicken manure 20 t ha-1 and inorganic fertilizer (Nitrogen) with a dose of 160 kg t ha-1 increased plant growth rate (LPT) aged 28-14 DAP by 90.62% compared to chicken manure 10 t ha-1 and inorganic fertilizer (Nitrogen) with a dose of 160 kg t ha-1. Chicken manure significantly increased plant length at 42 and 56 DAP, plant dry weight at 42 and 56 DAP, fresh root weight per clump (g), dry root weight per clump (g), and tuber dry weight per clump. clumps (g), tuber dry weight (sun) (kg m2) and yield (ton ha-1), but did not affect the growth components of shallot plants at the beginning of the observation. Inorganic fertilizers significantly increased the growth components, namely plant length, number of leaves, number of tillers, plant dry weight at the end of observation and dry weight (g clump-1) on shallot plants.
