  To investigate the effect of different planting densities on yield and yield components of quinoa (Titicaca cultivar), a factorial experiment based on complete randomized block design was studied at the Research Farm of the Agricultural and Natural Resources Research and Training Center of Kerman province in 2018-2019. Two inter-row space (30 and 50 cm) considered as the first factor and four intra-row space including 5, 10, 15 and 20 cm as the second factor. Increasing the intra-row and inter-row spacing resulted in significant reduction in CGR. Thus, the lowest value of this index, at both intra-row spacing attributed to 20 cm the inter-row spacing. The lowest grain yield (225.76 g.m-2) was related to the treatment of 50 cm inter-row and 20 cm intra-row spacings, Reduction intra-row spacing up to 10 cm resulted in a significant increase in seed yield. However, at in the inter-row spacing of 30 cm, there was no significant difference between the intra-row spacings in seed yield. The highest seed yield value was obtained from the intra- row spacing of 20 cm, with an average of 386.36 g.m-2. In general, the inter-row spacing of 30 cm and intra-row spacing of 15 and 20 cm resulted in highest seed yield and 1000 seed weight of quinoa in this research. Manuscript profile
