| dc.description.abstract | Shallots are a spice vegetable plant that plays a role as a daily complementary spice that has a high nutritional content and can be used as a raw material for medicines. The need for shallots continues to increase along with the increasing population. The use of organic fertilizers such as POC azolla and biosaka can support shallot production. This study aims to determine the effect of growth and production of shallots on the provision of POC Azolla and biosaka. This research was conducted at the Research Land of the Faculty of Agriculture, University of North Sumatra at an altitude of ± 25 meters above sea level starting from July to September 2024. This research used a Factorial Randomized Complete Block Design (RCBD) with 2 treatment factors with 3 replications. The first factor is the dose of POC azolla with 4 levels, namely 0, 30, 60, 90 ml/polybag. The second factor is the concentration of biosaka with 4 levels, namely 0, 1.3, 2.6, 4.0 ml/l of water. The administration of Azolla POC significantly increased the increase in plant length at 3 and 7 week after planting, the number of leaves at 3-7 week after planting, the number of tubers, tuber diameter, relative growth rate at 4-6 week after planting, fresh harvest weight of tubers and selling weight of tubers. The administration of biosaca significantly increased the relative growth rate at 2-8 week after planting. The interaction between the administration of Azolla POC and biosaca significantly increased the relative growth rate at 2-4 week after planting, fresh harvest weight of tubers and selling weight of tubers. | en_US |
