Studies on growth parameters in quinoa ( Chenopodium quinoa Willd.)

Abstract

Quinoa (Chenopodium quinoa willd.) is a pseudo cereal, which belongs to family amaranthaceae. Application of chemical fertilizers improves the nutrient availability in soil and high plant growth condition is seen, thus augment the seed yield. Keeping these views, the present investigation was undertaken at ZARS, UAS, GKVK, Bengaluru during Rabi 2018. The treatment combinations were arranged in factorial randomised block design with two replications which includes two factors, spacing and nutrient application, with 4 levels of spacing and 4 levels of nutrient application. The results revealed that, the treatment with spacing of 45x10 cm and high amounts of nutrient 150:75:75 kg NPK ha -1 recorded the highest growth parameters like plant height at 30 DAS (25.91 cm), 60 DAS (119 cm) and at harvest (122.28 cm), total number of branches plant -1 (17.70), total number of panicles plant -1 (17.63), length of glomerule (16.55 cm), where as in spacing with 55x10 cm and nutrient 150:75:75 kg NPK ha -1 recorded the highest values in days to 50 per cent flowering (51.97 %), days to maturity (89.32 days), field emergence (89.17 %) respectively.
