Effect of foliar application of proline and zinc on Growth, Yield and Some Metabolic Activities of Chenopodium quinoa Plants

This research examines the actual growth, yield and certain metabolic activities of quinoa plants in response to foliar treatments with Proline 25 ppm and Zn 50 ppm. Plants were grown in natural clay loamy soil conditions and treated with every of the aforementioned treatments. The treated plants showed significant responses in most of the growth and yield characteristics (lengths of shoots and roots, number of branches/plant, number of leaves/plant, plant biomass and weight of 1000-seed). Also, these treatments caused significant increases in the contents of photosynthetic pigments, soluble carbohydrates, soluble proteins, total phenols, endogenous phytohormone and mineral elements. This was the case during the entire duration of time period of the experiment.
