Abstract

Sweet corn is a high-value horticultural commodity with steadily increasing market demand. This study aimed to evaluate the production of sweet corn under different plant spacing and bokashi application. The research was conducted at the Horticultural Experimental Garden of Politeknik Negeri Lampung from July to October 2024, using a two-factor Randomized Complete Block Design (RCBD) with three replications. The first factor was plant spacing, consisting of three levels: 100 cm × 20 cm (JT1), 80 cm × 20 cm (JT2), and 60 cm × 20 cm (JT3). The second factor was bokashi application, also consisting of three levels: no bokashi (B0), 2.5 kg/m² bokashi (B1), and 5.0 kg/m² bokashi (B2). The results indicated that planting distance had a significant effect on all observed parameters. Bokashi application significantly influenced all observed parameters except stem diameter and cob diameter. No significant interaction was observed between planting distance and bokashi application. The 80 cm × 20 cm planting distance produced the highest yield, reaching 14.25 tons/ha. Bokashi application improved plant growth and yield compared to the control.

Abstract

Shallot (Allium ascalonicum L.) is an important horticultural commodity that contributes significantly to Indonesia's economy. However, its production declined in 2022–2023 compared to 2021. Fertilization plays a key role in improving soil fertility and supplying nutrients for optimal plant growth. This study aimed to assess the growth and yield response of the Brebes shallot variety to various doses of bokashi fertilizer and to determine the most effective dose. The experiment used a Randomized Complete Block Design (RCBD) with one factor: bokashi dosage, consisting of six treatments—B0 (control), B1 (1 kg/m²), B2 (1.5 kg/m²), B3 (2 kg/m²), B4 (2.5 kg/m²), and B5 (3 kg/m²). Each treatment was replicated four times with ten plants per replication, totaling 280 experimental units. The results indicated that bokashi application significantly affected leaf length, leaf diameter, bulb length, bulb diameter, fresh and dry bulb weight, as well as total yield per clump. The highest growth and yield were observed at the 3 kg/m² dosage. Thus, bokashi at 3 kg/m² is considered the most effective dose for improving the growth and productivity of the Brebes shallot variety.
