Study on the off-season shallot seed storage using biological pesticides in Kretek district, Bantul regency, Yogyakarta special region

Abstract

Farmers in the Samiran village use chemical pesticides to store their shallots. The purpose of this study was to examine the storage of shallot seeds from the off-season crops using biological pesticides. The research was conducted in March 2018 in the Ngudi Makmur farmer group. The research materials used were red onion varieties and biological pesticide of neem. The experimental design used was a completely randomized design with 3 factors with 2 replications. The factors were the type of biological pesticide (liquid and powder), storage treatment (hanging and in the basket), and the shallot varieties (Bimo, Crok Kuning, and Tajuk). The parameters observed were weight loss, damage level, growth capacity, and chemical composition. The results showed that the lowest weight loss was the storage of shallot off-season in the bucket with liquid pesticides on the Crok Kuning variety, while the high growth power test results were hanging. The treatment of biological pesticides can reduce the percentage of onion weight loss, while the use of powdered neem leaves can affect the weight loss, but it is not too high compared to the control. Hanging storage is better than basket storage because yield loss due to weight loss in basket is higher.
