Abstract

Background. Quinoa is a species with high nutritional value and interest has recently increased. This has been the basis of a series of studies aiming to find out its habitat and cultivation requirements to achieve higher yields and profits.  
Material and methods. A strict field experiment was established to analyze the effect of foliar fertilization with the micronutrient preparation Sonata beet, as well as of two seeding rates (2.0 and 3.0 kg of seeds of Chenopodium quinoa cv. ‘Faro’ per hectare), on vegetative characteristics and green matter yield. Seeds processed with the “vegetable” coat and “beet” coat were also used.
Results. Based on the study, it was found that the applied preparation Sonata beet had an effect on better development of the vegetative part of quinoa shoot and the total shoot length. Lower seeding rate of quinoa (2 kg·ha-1) stimulated a higher total shoot length as well as higher weight of the plants and their vegetative parts (stem and leaves). The use of the “vegetable” coat resulted in increased plant weight, as a result of increase in the weight of stem and leaves. The seeds in the “beet” coat were similar to the control (seeds without a coat) in respect of most morphological characteristics and green matter yield of plants.
Conclusion. The highest green weight yield of quinoa (101 Mg·ha-1) was obtained in 2011 after the use of the “beet” coat and a seeding density of 2 kg·ha-1, without the preparation Sonata beet.
