This study aims to evaluate the suitability of corn crop plant (Zea mays L.) and sweet potato (Ipomea batatas L.) in South Kualuh Subdistrict of North Labuhanbatu District. The method used in this research is survey method From the results of the overlay from the map of soil types, map of topography, and map of height place, retrieved 5 units of land use map. SPL 1 has an area of 34.95 hectares, SPL 2 has an area of 12.96 hectares, and SPL 3 has an area of 24.96 hectares, SPL 4 has an area of 159.85 hectares, and SPL 5 has an area of 73 hectares. The result at this research showed the highest potential of land suitability classes in set of land 1 is corn (S2 tc) and sweet potato (S2 tc, wa), in set of land 2 is corn (S2 tc) and sweet potato (S2 tc, wa), in set of land 3 is corn (S2 tc) and sweet potato (S2 tc , wa), in in set of land 4 is corn (S2 tc) and sweet potato (S2 tc, wa), in set of land 5 is corn (S2 tc) and sweet potato (S2 tc, wa).
Penelitian ini bertujuan untuk mengevaluasi kesesuaian lahan tanaman tanaman jagung (Zea mays L.) dan ubi jalar (Ipomea batatas L.) di Kecamatan Kualuh Selatan Kabupaten Labuhanbatu Utara. Metode yang digunakan dalam penelitian ini adalah metode survei. Dari hasil overlay peta jenis tanah, peta kemiringan lereng, dan peta ketinggian tempat, diperoleh 5 Satuan Peta Lahan (SPL). SPL 1 memiliki luas 34,95 ha, SPL 2 memiliki luas 12,96 ha, dan SPL 3 memiliki luas 24,96 ha, SPL 4 memiliki luas 159,85 ha, dan SPL 5 memiliki luas 73 ha. Hasil penelitian menunjukkan bahwa kelas kesesuaian lahan potensial tertinggi pada SPL 1 adalah jagung (S2 tc) dan ubi jalar (S2 tc, wa), pada SPL 2 adalah jagung (S2 tc) dan ubi jalar (S2 tc, wa), pada SPL 3 adalah jagung (S2 tc) dan ubi jalar (S2 tc, wa), pada SPL 4 adalah jagung (S2 tc) dan ubi jalar (S2 tc, wa), pada SPL 5 adalah jagung (S2 tc) dan ubi jalar (S2 tc, wa).
