【 摘 要 】

Evaluation of land suitability for shallot (Allium ascalonicum L.) and lemon (Citrus sp.) aimed to determine the level of suitability to the plants that would be cultivated at Harian District, Samosir Regency. Operation of soil type, altitude map and slope maps with scale of 1:50000 obtained nine Land Map Units namely LMU1 and 2 - Sampur Toba village; LMU3 - Janji Martahan village; LMU4 - Turpuk Limbong village; LMU5 - Sosor Dolok village; LMU6,7,8 and 9 in Partungkox Na Ginjang village. Land suitability assessment criteria based on Bogor Soil Research Center Staff 1983 and the limit method by Djaenuddin 2011. The results showed that shallot crop, there is only on LMU 2 (Sampur Toba) that has barier that can be overcome, such as actual class S3 (n, r); S2 (eh) had an inhibiting factor pH and slope that can be managed with liming and terracing. Orange crop on LMU 1 can be overcome by giving organic material; it might be overcome with terracing on LMU 3; and managed by liming and terracing on LMU 8. On the other LMU (4, 5, 6, 7, 9) are not suggested for orange cultivation.
