Uji Masa Simpan Pupuk Hayati Dengan Kombinasi Pupuk Npk Terhadap Pertumbuhan Dan Produksi Tanaman Bawang Merah (Allium Ascalonicum L.) Pada Lahan Mineral Masam
ABSTRACT
Onion plants (Allium ascalonicum L.) are plants originating from Asia that have a
high selling value. Efforts can be made to increase shallot productivity and
increase soil fertility by applying biological fertilizers. The use of biological
fertilizers is not sufficient in meeting the needs of nutrients needed by shallots
optimally, so it needs to be combined with NPK fertilizers. Giving a combination
of inorganic fertilizers and organic fertilizers has a good impact on plants.
Microbes in a biofertilizer formulation can experience deterioration during the
storage period, efforts are needed to determine the appropriate bacterial storage
period. The carrier material used in this study as a storage medium is Mucuna
bracteata. This research was conducted in Langsat Permai Village, Bunga Raya
District, Siak Sri Indrapura Regency, Riau Province for six months starting from
January 2024 to June 2024. This research was conducted experimentally using a
completely randomized design (CRD) consisting of 7 treatments and 4
replications. The treatments were P1: 100% inorganic fertilizer; P2, P3, P4: 75%
inorganic fertilizer + sludge palm oil + 10 ml biofertilizer (10% M. bracteata)
shelf life 0, 1 and 2 months; P5, P6, P7: 50% inorganic fertilizer + sludge palm oil
+ 10 ml biofertilizer (10% M. bracteata) shelf life 0, 1 and 2 months. The
parameters observed were plant height, number of leaves, harvest age, tuber
diameter, number of tubers per plant, weight of tubers per plant, weight of wet
tubers per 1 m2, weight of tubers worth saving 1 m2. Observation data were
analyzed statistically using variance analysis, and the results of variance analysis
were tested with Duncan's test at the 5% level.
