THE EFFECT OF BOKASHI OF SHALLOT STRAW FERTILIZER TO THE GROWTH AND YIELD OF SHALLOT (Allium ascalonicum L.) CV. BIMA

Abstract

Shallot waste, in the form of stover, is often a problem at shallot marketing locations. To
overcome this problem, stover can be further processed into bokashi compost. This study
examines the effect of bokashi compost doses on shallot plants. The experiment was conducted in
Silihasih Village, Babakan District, Cirebon Regency, from August to October 2021. A randomized
complete block design (RCBD) was used to test the effect of shallot bokashi doses (0, 10, 20, 30,
40, 50, and 60 t ha-1) on shallot growth and yields. The observed growth variables were plant
height, number of leaves and shoots per clump, root volume, shoot-to-root ratio, and plant growth
rate. The observed yield components and yield variables were bulb diameter, fresh bulb weight
per clump and per plot, and dry bulb weight per clump and per plot. The statistical analysis used
was analysis of variance with post hoc Duncan's Multiple Range Test. The results showed that
shallot stover bokashi can increase shallot growth and yield. Shallot stover bokashi of 20 and 60
t ha-1 produced higher dry weight of bulbs per plot than other treatments, namely 3.22 and 3.16
t plot-1.
