Respone of Growth and Production of Shallots (Allium ascalonicum L.) with Application Water Hyacinth Compost and Arbuscular Mycorrizal Fungi

Abstract

This study aims to determine the effect of the growth response and production of shallot (Allium ascalonicum L.) with the application of Eichhornia crassipes compost and arbuscular mycorrhiza fungi, carried out in the experimental garden of the Faculty of Agriculture, University of Medan Area, which is located at Jalan PBSI No. 1 Medan Estate, Percut Sei Tuan District from November to January 2020. The research method used was factorial randomized block design (RAK), namely the treatment factor of giving Eichhornia crassipes compost (E) with 4 levels, namely: E0 = No treatment, E1 = Eichhornia crassipes compost 0.5 kg/m2 (5 tons /ha), E2 = Eichhornia crassipes Compost 1.0 kg/m2 (10 tons/ha), E3 = Eichhornia crassipes Compost 1.5 kg/m2 (15 tons/ha) and application factor of arbuscular mycorrhiza fungi consisting of 4 treatment levels, namely: M0 = No AMF inoculants (Control), M1 = 10 g/m2 AMF inoculants (100kg/ha), M2 = 15 g/m2 AMF inoculants (150kg/ha), M3 = 20 g/m2 AMF inoculants (200kg/ha).The results showed that the application of water hyacinth compost at a dose of 15 tons/ha gave the highest yield to increase plant height, number of tillers, tuber wet weight per sample, tuber wet weight per plot, tuber dry weight per sample, tuber dry weight per plot. onion plant. Arbuscular mycorrhiza fungi application treatment with a dose of 200 kg/ha gave the highest yield in increasing plant height, number of tillers, wet weight of bulbs per sample, wet weight of bulbs per plot, dry weight of bulbs per sample, dry weight of bulbs per plot of shallots.
