Metode penelitian menggunakan metode regresi linier berganda dengan range tahun 2001 sampai 2015.
Hasil penelitian ini didapatkan bahwa ketersediaan padi dan jagung di Kabupaten Karo memiliki nilai koefisien determinasi R2 yang sama yakni sebesar 0,98 yang berarti sebesar 98% variabel bebas padi dan jagung tersebut berpengaruh terhadap variabel terikat yakni ketersediaan padi dan jagung, sedangkan sisanya 2% dipengaruhi oleh variabel bebas lain. Secara serempak ketersediaan padi di pengaruhi luas panen padi, konsumsi beras, harga domestik beras dan harga impor beras.

The result of the research showed that the availability of rice and corn in Karo Regency had the same coefficient determination R2 at 0.98 which indicated that 98% of independent variables of rice and corn had the influence on dependent variable, the availability of rice and corn, while the remaining 2% was influenced by the other independent variables. Simultaneously, the availability of rice was influenced by the rice harvesting area, rice consumption, rice domestic price, and rice imported price.
