The present experiment entitled “Influence of sowing time and planting geometry on biochemical parameters of quinoa (Chenopodium quinoa Willd.)” was carried out at Post Graduate Institute, Mahatma Phule Krishi Vidyapeeth, Rahuri. The field experiment was conducted at the PGI Farm, M.P.K.V., Rahuri, during the Rabi 2019-20 and Rabi 2020-21, and the laboratory experiment was carried out at Seed Technology Research Unit (STRU), Mahatma Phule Krishi Vidyapeeth (MPKV), Rahuri. It is essential to focus on developing edible cultivars with superior quality and higher seed yield with suitable growing periods on particular dates because early or late sowing causes reduction in yield and seed quality of crop. The objective of the study was to the effect of different sowing times and planting geometry on biochemical compositions such as protein and oil content of quinoa. two genotypes (IC-411824 and EC-507739) were sown at three different sowing times (15th November, 1st December, and 15th December) with three different spacing (30 × 10 cm, 45 × 10 cm, and 60 × 10 cm), the harvested seeds were stored until germination percentage declined below 70.00 % and observations for biochemical constituents such as protein and oil content were recorded at initial and at 90, 180, and 240 days after storage by using Factorial Completely Randomized Design (FCRD) design. In terms of biochemical parameters protein and oil percentage, the 15th November sowing had maximum protein and oil percentage throughout the storage periods, however, spacings had no influence on protein and oil content in quinoa during 240 days of storage. Referring to genotypes, genotype EC-507739 recorded maximum protein and oil percentage during 240 days of storage. All the interactions viz., sowing time and spacing, sowing time and genotype, spacing and genotype, and sowing time, spacing and genotype were found non-significant.

Quinoa, protein, oil, genotypes

The highest protein and oil content was recorded in genotype EC-507739 as compared to IC-411824 on all three dates of sowing during 240 days of storage.
