Yield Potential of Shallots Bulbil Planting Materials with Liquid Organic Fertilizer Treatment out of Season

Abstract

The main problem with shallots in Indonesia is planting material. The use of consumption tubers as planting material is very high. Efforts are needed to replace consumption tuber planting material with other planting materials such as aerial tubers. This study examines the potential yield of aerial tuber planting material and consumption tuber with fertilization treatment. The study used a Completely Randomized Block Design with a split-plot pattern with two factors, namely: fertilizer (as the main plot) with two levels, namely: with liquid and chemical fertilizer. Types of planting material (as a subplot) with three levels, namely aerial tubers, large consumption tubers (1.93-2.05 cm) and small consumption tubers (1.04-1.29 cm). Repeat three times. Liquid organic fertilizer can be used to improve the chemical quality of the soil. The combination of bulbils planting material with chemical fertilizer resulted in the highest fresh weight of bulbs per plot and dry weight of bulbs per plot, namely 394.67 grams and 338.67 grams, respectively. However, the highest number of bulbs planted in the treatment of large consumption bulbs was 7 bulbs. The diameter of bulbs produced from bulbils planting material and bulb consumption was the same. Shallot bulbs have potential as planting material.

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

“…The average yield of optimum plant fresh weight was found in the treatment of 100% liquid organic fertilizer. This is because organic fertilizers can increase root activity in absorbing water and nutrients in the metabolic process because organic fertilizers have an effect and a positive correlation on root biomass and the number of shallot bulbs [15]. Treatment of 50% inorganic fertilizer and 50% liquid organic fertilizer showed the optimum bulb weight of 54.33 g (Table 2).…”
