Title: “Seed quality of quinoa (Chenopodium quinoa Willd.) influenced by geometry and fertility levels”
Quinoa (Chenopodium quinoa Willd.) is a native of the Andes that has sparked a worldwide interest due to its unique nutritional value.It is characterised as pseudo-cereals crops, with broad leaf plant and starchy dicotyledonous seed and consequently not a cereal. It can be used as a substitute for dairy proteins. Quinoa seed have an orthodox magnificent nutritional food quality and were also called “the mother grain”. Furthermore, the quinoa plant is cold, salt and drought resistant, which is why it is known as the "golden grain”.
The current investigationwas conducted in kharif2022, withgenotype “EC507742” at Research and Extension Centre, Gaja, College of Forestry, Ranichauri (Tehri Garhwal). The experiment comprised of two factorsviz., geometry (S): S1-20 x10 cm, S2-30 x 10 cm and S3-40 x 10 cm in main plot and fertility levels (F): F1- Control, F2- 75% NPKS, F3- 100% NPKS and F4- 125% NPKS in sub plot with total of 12 treatment combinations that were evaluated in split plot design with three replications.The seed obtained after harvest were analysed for seed quality parameters in 2 factors complete randomized design with three replicates at Department of Seed Science and Technology, College of Forestry, Ranichauri.The data was analysed using OPSTAT with figures from SAS (procglm).
Among the geometry, S2 (30 x 10 cm) performed well in field conditions compared to others. Among various fertility levels, F3 (100% NPKS) showed maximum growth, yield attributes, yield and higher returnof quinoa as compared to other fertility levels.
On the basis of laboratory experiments, wider spacing of S3 (40 x 10 cm) performed well as compared to other geometry. Among different fertility levels, F3 (100% NPKS) showed significant results over others.Also, the interactions between geometry and fertility levels were found significant for growth, yield attributes, yield and quality parameters under standard germination and stress tolerance tests.
Based on the study, it can be concluded that application of recommended fertilizer (100% NPKS) with optimum spacing of 30 x 10 cm enhances the growth, yield and higher return of quinoa and with wider spacing of 40 x10 cm enhances the seed quality of quinoa.
