EFFECT OF CON CO VANG MICRO - ORGANIC FERTILIZERS ON THE YIELD AND SEED QUALITY OF ATLAS QUINOA GROWN ON BASALT AND ACRISOL SOIL IN TAY NGUYEN

Abstract

The study aims to identify the formula of Con Co Vang micro-organic fertilizer applied to the Atlas cultivar of quinoa grown on basalt soil and on acrisol soil, which produces high yield, high total protein content and matches with Tay Nguyen’s agro-ecological conditions. Applying six formulas of micro-organic fertilizers and one reference formula, Atlas quinoa cultivar was grown in the dry seasons of 2024 at a density of 100,000 plants/ha (row spacing of 50 cm, plant spacing of 20 cm). Research showed that the first formula (CT1 - 2 ton/ha/crop) was the most suitable for Atlas quinoa grown in the selected area. The formula provided the highest theoretical yield of the Atlas cultivar (with 28.56 quintal/ha/crop on basalt soil and 22.19 quintal/ha/crop on acrisol soil) and the highest actual yield (22.95 quintal/ha/crop on basalt soil and 17.50 quintal/ha/crop on acrisol soil). Moreover, the first formula also resulted in the highest total protein content (21.68% on basalt soil and 22.86% on acrisol soil) and relatively high starch content (65.43% on basalt soil and 63.07% on acrisol soil).
