Physiological performance of quinoa (Chenopodium quinoa willd.) under agricultural climatic conditions in Boyaca, Colombia

Abstract

Quinoa (Chenopodium quinoa Willd.) is native to South America; it is characterized by its high nutritional composition and high adaptation capacity to diverse edapho-climatic conditions, which highlights how genetic variability is expressed as multiple physiological and phenological responses. The objective of this research was to evaluate the physiological response and proximal composition of the grain to three types of fertilization under the environmental conditions in the municipality of Oicata (Boyaca, Colombia), located at 2,875 m a.s.l. In this place, the white Soracá variety was planted using a completely randomized design with four treatments and four repetitions. It was observed that the fertilization sources have an effect on the physiological and phenological behavior, mainly on the number of leaves, length of stem and chlorophyll content. In addition, the proximal composition of seeds changes, which is attributed to the application of mineral organic fertilizer that improves the production of quinoa grains, while N-P-K contribution shows greater growth and vegetable development, but less yield.
