| Abstract | ||||
| Two trails were conducted during 2019/2020 and 2020/2021 seasons, to investigate the influence of four planting date and four plant distribution treatments on quinoa growth, yield, its attributes and quality. Each experiment was performed in randomized complete blocks design (RCBD) in a split-plot arrangement with three replications. Sowing dates were allocated in the main plots and plant distributions were assigned to the sub-plots in both seasons. The results indicated that, the planting date in both seasons significantly affected all studied traits except P.H.(cm.) and H.I. in the 1st one. The fourth planting date (a4) recorded the highest seed yield /plant of 39.49 and 57.30 g., seed yield /fed. of 1.82 and 2.58 ton in both seasons., biological yield/fed. of 5.99 ton and harvest index43.18% in the second season, as well as improved all studied quality traits in both seasons except seed moisture% in the second one. Plant distributions treatment possessed highly significant effect on plan height, main panicle length cm., seed yield/plant (g.) and S.Y /f.(ton) in 2nd season, all quality parameters in both seasons and significant effect only on plan height in the first season, the third plant distribution treatment (b3) improved seed yield/plant of 51.75 (g.) and S.Y /f. of 2.33(ton) in the 2nd one. | ||||
