Maize productivity in Indonesia currently is still around 5.1 t/ha. This result is still low when compared to research results which have reached 8.0 t/ha on dry land. One of the reasons for the low productivity of maize is the lack of application of cultivation technology at the farmers level. There is still possibility to increase the productivity of composite maize varieties in dry land by increasing the plant population. In addition, application of an intercropping system of maize with legumes can help increase maize yields. This study was conducted in Labuhan Lombok Village, Pringgabaya District, East Lombok Regency, West Nusa Tenggara Province of Indonesia from August to December 2019. The experiment was arranged according to a Randomized Block Design by testing 2 treatment factors, namely (1) mycorrhizal inoculation consisting of two levels (M0 = without mycorrhizal inoculation; M1 = with mycorrhizal inoculation), (2) the number of mungbean inserts consisting of three levels (D0 = maize cultivation without mungbean inserted; D1 = maize cultivation with 1 row of mungbean inserted; D2 = maize cultivation with 2 rows of mungbean inserted) and each treatment was replicated 3 times therefore 18 experimental plots were obtained. Results showed that maize cultivation in dry land and dry climate with double row planting system inoculated with mycorrhizae and insertion of two rows of mungbean was much better than inserting 1 row of mungbean because the difference in yield obtained was much smaller, namely 6% or 490 kg compared to monoculture yields, but from the results of the profit evaluation based on the calculation of the Land Equity Ratio, the insertion of 1 row of mungbean was much higher, namely 2.62 compared to the insertion of two rows of mungbean which only obtained a result of 2.25.
