The effect of biocompost Trichoderma spp. tablet in stimulating shallot growth and yield for climate change adaptation

Abstract

The use of fertilizers that are appropriate and right on target is necessary to assist plants in dealing with conditions of climate change to extreme climates that cause the soil to become dry and less fertile. To deal with climate change adaptation and increase the productivity of shallots, a study aimed to determine the effect of biocompost dosage Trichoderma spp. tablet in spurring growth and yield of several shallot varieties. The research used an experimental method which was conducted in Sembalun Bumbung Village, East Lombok Regency. This study used a Randomized Block Design with a factorial experiment. The main factor is the dosage of biocompost tablets, namely: 0 g/plant, 2.5 g/plant, 5 g/plant, 7.5 g/plant, and 10 g/plant. The simple factor is that the shallot varieties, namely: Bali Karet, Ampenan, Keta Monca, Super Philip and Super Cros. The results showed that the dosage of biocompost tablets starting at 5 g/plant can stimulate growth and can increase the weight of harvested dry tubers. Bali Karet varieties are very adaptive so that the growth and yield of dry tuber weight are the highest, Ampenan and Keta Monca are adaptive in the highlands, while Super Philip and Super Cross are less adaptive.
