The role of vermicompost and PGPR on growth and formation of bulbils shallot (Allium cepa L. Aggregatum)

Abstract

One of the effects of climate change is a decrease in land productivity and subsequently causes a decrease in crop production. The decrease in land quality will be higher with the use of inorganic fertilizers. Alternative solutions to these problems are the use of vermicompost fertilizers and PGPR. The aim of this research was to examine the role of Vermicompost fertilizers and PGPR on the growth and formation of bulbil tubers. The research design used Randomized Complete Block Design (RCBD) with 2 factors, the first factor was Vermicompost (5 tons ha−1, 10 tons ha−1, 15 tons ha−1, 20 tons ha−1), the second factor was PGPR (with PGPR and without PGPR), repeated as many as 3 times. The results showed that the combination of Vermicompost and PGPR significantly affected the number of bulbils, the combination of vermicompost 5 tons ha−1 + with PGPR produced the highest bulbils. Vermicompost and PGPR had no significant effect on plant height, net assimilation rate, fresh weight, bulb weight, number of bulbils, and number of bulbs. There was no significant interaction between the treatment of vermicompost and PGPR on plant height, net assimilation rate), fresh weight, bulb weight, and a number of bulbs.

Growth and Yield of Screenhouse-grown potted Pechay (Brassica rapa L. ssp. chinensis cv. Black Behi) in selected Davao-produced Composts

“…Treatments with vermicompost amendments resulted in higher mean plant heights (Table 3) compared with plants grown in DBB and both controls. A similar response was observed in sorghum (Sorghum bicolor L. Moench) and shallot (Allium cepa L. Aggregatum) in which a higher dosage of vermicompost significantly increased plant height (Nohong et al, 2020;Triharyanto et al, 2021).…”

Pengaruh Giberelin (GA3) terhadap Pertumbuhan dan Komponen Hasil Bawang Merah (Allium cepa var. aggregatum) Varietas Bima Brebes

“…Salah satu zat pengatur tumbuh yang dapat meningkatkan daya berkecambah benih bawang merah, yaitu Gibberellic Acid (GA3). Giberelin berperan dalam peningkatan beberapa bagian pada tanaman seperti, tinggi tanaman, jumlah daun per tanaman, perpanjangan batang, persentase pembungaan pada tanaman, stimulasi dan sinkronisasi pembungaan, perkembangan biji, jumlah biji per tangkai bunga, dan bobot biji per tangkai bunga dalam umbi (Triharyanto et al, 2016).…”

Potential of Liquid Organic Fertilizer on Flowering, Yield of Shallots (Allium cepa L. Aggregatum) and Soil Quality

“…The shallot consumption of the Indonesian population increased in 2018. However, the productivity of shallots is still relatively low [1]. The Central Statistics Agency (2019) stated that in 2014-2017, the national productivity of shallots decreased from 10.22 tons/ha to 9.29 tons/ha, so the production of shallots in Indonesia has not yet met the level of consumption [2].…”
