The Combination of Biofertilizer and Organic Fertilizer to Improve Shallot (Allium ascalonicum L.) Production

Abstract

Shallot is one of important horticultural crops in Indonesia; shallot consumption per capita is estimated to be 4.6 kg per year. The objective of this study was to evaluate the effect of combining biofertilizer and organic fertilizer on the production of shallot in Sukabanjar village, Pesawaran, Lampung, Indonesia. The study was set up using a randomized completely block design with two factors, biofertilizers and various organic fertilizers, i.e. cow manure, chicken manure, rice straw compost, oyster mushroom baglog. Our study demonstrated that combining biofertilizer and organic fertilizer significantly increased the number, diameter, and fresh and dry weight of tubers of “Bima Brebes” shallot. Shallots treated with biofertilizer combined with oyster mushroom baglog produced the highest tuber yield of 1788 g compared to 282 g in the control.

Shallot growth and production responses to application of microorganisms based-biostimulant and NPK fertilizer combinations on acid soil

“…The shallot seed of the Bima Brebes cultivar was chosen due to its short season, namely, it has a harvest time of 55-60 DAP faster than other shallot cultivars at 60 -90 DAP; it grows well in the rainy season; the tubers have medium to large size, and pink to maroon tuber color, making them preferred by consumers [20]. The Bima Brebes variety shallot seeds had a tuber weight ranging from 2-4 g/tuber, were quite old, had been kept for 60-90 days, were of good quality, were free of pests and diseases, and had been dried for two months.…”
