Abstract

Soil's physical properties are one of the factors that influence the productivity of shallots. This research aims to determine the correlation of soil's physical properties towards productivity of shallots in Watershed of Lake Toba. This research was carried out in the center of the shallot planting area in the area of Lake Toba, Muara District, Bakti Raja District, Silahisabungan District, Merek District, Haranggaol District, and Samosir Island, which have at altitude 911 – 1432 meters above sea level. This research used survey methods which includes literature studies, preparation of the questionnaire, survey around of Lake Toba and processing data from survey in Lake Toba area. The results showed that soil's physical properties and the productivity of shallots had a correlation with value of r = 0.71. The best soil texture for the cultivation of shallots in Watershed of Lake Toba is sandy loam.

Sifat fisik tanah merupakan salah satu faktor yang berpengaruh terhadap produktivitas bawang merah. Penelitian ini bertujuan untuk mengetahui hubungan sifat fisik tanah terhadap produktivitas bawang merah di daerah tangkapan air Danau Toba. Penelitian ini dilaksanakan di sentra kawasan penanaman bawang merah di daerah sekitaran Danau Toba yaitu Kecamatan Muara, Kecamatan Bakti Raja, Kecamatan Silahisabungan, Kecamatan Merek, Kecamatan Haranggaol, dan Pulau Samosir. Ketinggian tempat 911-1432 meter diatas permukaan laut. Penelitian ini dilaksanakan dengan metode survei dan kuisioner serta pengolahan data dengan analisis regresi pada aplikasi SPSS. Hasil penelitian menunjukkan bahwa sifat fisik tanah dan produktivitas bawang merah memiliki hubungan dengan nilai r = 0.71. Tekstur tanah yang terbaik untuk budidaya bawang merah di DTA Danau Toba adalah lempung berpasir.
