This research aimed to examine yield performance of mungbean (Vigna radiata (L) Wilczek) cv. “Kenari” relay-planted at different dates and spacings between double-rows of maize plants that were either fertilized or unfertilized with mycorrhiza biofertilizer. The field experiment, conducted on dry land in Pringgabaya village, East Lombok, Indonesia, from August to December 2019, was arranged according to Split Split Plot design with three blocks and three treatment factors, i.e. application of mycorrhiza biofertilizer to maize plants as main plots (M0= without; M1= with biofertilizer), relay-planting dates of mungbean between double rows of maize plants as subplots (T1= -10; T2= 0; T3= +10 days of maize planting date), and mungbean row spacings as sub-subplots (S1= 50 cm; S2= 33 cm). Results indicated that yield components of mungbean relay-planted between double rows of maize were significantly affected by application of mycorrhiza biofertilizer to maize plants, relay-planting dates of mungbean, and row spacings of mungbean, except for the weight of 100 grains. There were significant interaction effects, but only between mycorrhiza application to maize and planting dates of mungbean on weight of dry filled-pods and grain number per clump as well as their intercropping ratios, indicating that without mycorrhiza application to maize plants, grain number of the mungbean plants per clump was the most badly affected by delaying planting dates of mungbean, but under micorrhiza biofertilized maize plants, grain number was not affected by the delay, especially between D-10 and D0, indicating positive effect of mycorrhiza biofertilizer in this intercropping system.
