Abstract

Shallots are one of the leading commodities that have high economic value. The majority of farmers in Rejoso District are cultivating shallots. The research area has great potential in producing shallots, this can be seen in 2018 shallot production of around 48,864 tons with a percentage of 32.06% and in 2019 around 57,093 tons with a percentage of 35.14% (BPS Nganjuk Regency, 2020:120). The great potential of shallot productivity is not matched by more detailed information on the distribution of land that has high land suitability for shallots. This study aims to produce information on the distribution of land suitability for shallot farming.

This study uses a method scoring with a spatial analysis approach. The method is scoring used to analyze land suitability by assigning a value to each parameter to determine land units. The research was conducted in Rejoso District, Nganjuk Regency. This research uses rainfall map parameters, slope maps, temperature maps and soil type maps. 

The results of data analysis show that there are five land units in Rejoso District. The shallot land in Rejoso District is mostly classified as very suitable, with a very suitable land area of ​​around 5,599 ha in land unit 1 and 6,119 ha in land unit 2. The value is quite suitable for land unit 3 with an area of ​​773.6 ha. The marginal appropriate value on land unit 4 has an area of ​​2,609 ha and the inappropriate value on land unit 5 has an area of ​​about 546.9 ha. The limiting factors in the research area are rainfall, slope and soil type.
