Evaluation of Yield and Yield Components of Quinoa (Chenopodium quinoa Willd) in as affected by Different Planting Densities

Abstract

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.
