The objective of this researchis to evaluate the land suitability Upland rice (Oryza sativa L.)and Onion (Allium ascalonicumL.) in Kualuh Hulu Subdistrict of North Labuhanbatu District. The methode of this research is the survay method. From the results of the overlay from the map of soil types, map of topography, and map of height place, retrieved 9 units of land use map. SPL 1 has a land area of22.273,98 hectares, SPL 2 has a land area of 12.248 hectares, SPL 3 has a land area of 8.571,24 hectares, SPL 4 has a land area of 8.015,46hectares, SPL 5 has a land area of 4.736,61 hectares, SPL 6 has a land area of 3.154,86 hectares, SPL 7 has a land area of 2.044,73 hectares, SPL 8 has a land area of 1.445,39 hectares and SPL 9 has a land area of 946,28hectare. The conclusionof this research showed the highest potential of land suitability classes in set of land 1 is upland rice ( S3 rc ) and onion ( S3 wa, rc ),in set of land 2 is upland rice (N rc) and onion( N rc ), in set of land 3 is upland rice ( S1 ) and onion ( S3wa ), in set of land4 is upland rice( N rc ) andonion ( N rc ), in set of land 5 is upland rice (S3 rc ) and onion ( S3 wa rc ), in set of land 6 is upland rice (S1) and onion (S3 wa ), in set of land 7 isupland rice(S3 rc ) and onio (S3 wa rc), in set of land 8 is upland rice (S3 rc ) and onion ( S3 wa rc ) and in set of land 9 is upland rice ( S3 rc ) and onion (S3 wa rc).
Penelitian ini bertujuan untuk mengevaluasi kesesuaian lahan tanaman Padi Gogo (Oryza sativa L.) dan Bawang Merah (Allium ascalonicum L.) di Kecamatan Kualuh Hulu 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 9 Satuan Peta Lahan (SPL). SPL 1 memiliki luas 22.273,98 ha, SPL 2 memiliki luas 12.248 ha, SPL 3 memiliki luas 8.571,24 ha, SPL 4 memiliki luas 8.015,46 ha, SPL 5 memiliki luas 4.736,61 ha, SPL 6 memiliki luas 3.154,86 ha, SPL 7 memiliki luas 2.044,73 ha, SPL 8 memiliki luas 1.445,39 ha dan SPL 9 memiliki luas 946,28 ha. Hasil penelitian menunjukkan bahwa kelas kesesuaian lahan potensial pada SPL1 adalah padi gogo ( S3 rc ) dan bawang merah ( S3 wa, rc ), pada SPL 2 adalah padi gogo (N rc) dan bawang merah ( N rc), pada SPL 3 adalah padi gogo ( S1 ) dan bawang merah( S3 wa ), pada SPL 4 adalah padi gogo ( N rc ) dan bawang merah ( N rc ), pada SPL 5 adalah padi gogo ( S3 rc ) dan bawang merah ( S3 wa, rc ), pada SPL 6 adalah padi gogo( S1 )dan bawang merah ( S3 wa ), pada SPL 7 adalah padi gogo ( S3 rc) dan bawang merah( S3 wa, rc ), pada SPL 8 adalah padi gogo ( S3 rc ) dan bawang merah ( S3 wa, rc ), pada SPL 9 adalah padi gogo ( S3 rc ) dan bawang merah ( S3 wa, rc ).
