The quantity of crop production is determined by the suitable selection of maize and soybean varieties, as well as the condition of intercropping area. Plant density management is performed in such a manner that more growth area is available for plants to grow and develop. Study on the nitrogen and phosphor status and yields of several maize and soybean varieties which are cultivated with the intercropping system was carried out on farmers’ land in Akar Akar Village, Bayan District, North Lombok Regency, on May-August 2020. The purpose of this work was to investigate the status of nitrogen and phosphorus nutrients, as well as yields, from a variety of maize and soybean grown in dryland intercropping systems. Five maize and soybeans were planted in a randomized block pattern with an intercropping system of each three rows of maize and soybeans. The varieties are: V1: NK212 maize: Biosoy I soybean, V2: Bima 20 URI maize: Dega I soybean, V3: NASA 29 maize: Detap soybean, V4: Bisi 18 maize: Biosoy II soybean, and V5: Srikandi maize: Anjasmoro soybean. The findings revealed that the V4 treatment (Bisi 18 maize: Biosoy II soybean) provides the best nitrogen and phosphorus nutritional status and yields from the intercropping system of 3 rows of maize: 3 rows of soybeans. This study found that improving nitrogen and phosphorus status by intercropping each three rows of Bisi 18 maize and Biosoy II soybean on sandy land with an eco-friendly fertilizer implementation may help ensure environmental sustainability.
