Shallots are the main commodity in household consumption
and the food industry in Indonesia. Shallot production has not yet met demand,
even though it has shown positive growth over the last two decades. By use of
biological fertilizer containing Trichoderma sp. proposed as a solution to
increase crop productivity, as well as reduce dependence on synthetic
chemicals, especially in off-season cultivation. This study aims to identify
the effect of biological fertilisers and inorganic fertilisers on the growth
and yield of shallots and Knowing the best combination of biofertilisers and
inorganic fertilisers that can increase growth and the best yield in
shallots.This research took place in the Green House A, Sebelas Maret
University, Surakarta city, Indonesia. The research was conducted in
Februay-April 2024. The research design that used was a Complete Blok Design
(CRD) consisting of two factors with three replications. The first factor was
inorganic fertilizer (100, 75, 50% inorganic fertilizer). The second factor was
biological fertilizer (without fertilizer, 10, 20, 30 g/plant). Data were
analyzed by using ANOVA and Duncan's Multiple Range Test with a significance
level of 5%. The research results showed that reducing inorganic fertilizer had
an effect on plant fresh weight, fresh tuber weight and plant dry weight.
Providing Trichoderma fertilizer affects the weight of fresh tubers. The best
combination to increase shallot yields is 50% inorganic fertilizer + 20g
Trichoderma fertilizer/plant.
