The investigation was conducted to study the effect of various agronomic factors viz., geometry and fertility levels on growth dynamics and yield of quinoa (Chenopodium quinoa Willd.), often referred to as superfood and also called “the mother grain”.
The investigation was conducted in kharif 2022, with genotype “EC507742” at mid-hill region of Uttarakhand, India comprising of two factors viz., geometry (S): S1- 20 cm × 10 cm, S2- 30 cm × 10 cm and S3- 40 cm × 10 cm as main plots and fertility levels (F): F1- Control, F2- 75% NPKS, F3- 100% NPKS and F4- 125% NPKS as sub plots with total of 12 treatment combinations that were evaluated in split plot design with three replications and analysed using OPSTAT with figures from SAS (proc glm).
The 30 cm × 10 cm spacing was found effective in field conditions compared to other crop geometries, indicating to be more suited for quinoa cultivation under 100% NPKS fertilizer application which produced best growth dynamics, yield characteristics and yield for quinoa. The interaction between the 30 cm × 10 cm spacing and 100% NPKS fertilizer was significant in recording the highest growth dynamics and yield. Analysis indicates that quinoa responds very well to fertilizer dose of 100% NPKS at an optimum spacing of 30 cm × 10 cm.
