To investigate the effect of spacing and nitrogen level on Quinoa growth and yield, a field experiment wasconducted at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SamHigginbottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj (UP) in 2019-20and 2020-21. The Split Plot Technique was used to duplicate 20 treatments with varying combinations ofcrop stand geometry and nitrogen delivery doses using urea. The major goal of the study was to determinehow crop stand geometry and nitrogen treatment dosages affected Quinoa development and yield. Cropstand geometry include (15 x 10) cm, (25 x 10) cm, (35 x 10) cm, and (45 x 10) cm, with nitrogen managementoptions including control, 25 Kg/ha, 50 Kg/ha, 75 Kg/ha, and 100 Kg/ha of RDN. Growth attributes viz.,leaf area and number of leaves significant and maximum were recorded in the treatment spacing and (S4)crop spacing 45cm x 10 cm except leaf area index because it was recorded in (S1) crop spacing 15 cm x 10 cm,respectively. Based on the data obtained of yield and yield attributes significant and maximum by planting(S1) crop spacing 15cmx10cm (Grain yield, 2.35 and 2.33 t/ha) and (S4) crop spacing 45 cm x 10 cm spacing(Number of panicle per plant, 19.75 and 16.93) and (Number of spikeletâs per panicle, 18.67 and 16.65)during both the year, respectively. Nitrogen management treatment rate of 100 kg/ha of RDN was recordedsignificant and maximum growth attributes and yield attributes (Number of panicle per plant, 19.32 and16.34), (Number of spikeletâs per panicle, 18.78 and 18.02) (Grain yield, 2.27 and 2.30 t/ha) during both theyear, respectively.
