Abstract
Shallot cultivation is usually carried out on land with a lack of sunlight, so that the selection of shade-adaptive shallot genotypes is very important. This study aimed to know yield potential and tolerance level of varieties of shallots in sunlight deficit. This study was arranged using a Completely Randomized-Split Plot Design with five replications. The genotypes used were Keta Monca, Lokananta, Bali Karet, Ampenan, Thailan Nganjuka and Super Philip. The sunlight deficit was carried out using a black paranet with 65% sunlight barrier. The experiment results showed that shallot varieties have different yields potential against sunlight deficit stress. Shallot crop under sunlight deficit stress caused a reduction in bulb wet weight, bulb dry weight, leaf wet weight, number of bulbs, root dry weight, and leaf dry weight. The Lokananta variety produced the heaviest wet weight of bulb per clump (33.7 g per clump) with a decrease in bulb wet weight only 4.8% under sunlight deficit conditions, and the sensitivity index value was moderate tolerant to sunlight deficit
