Effect of molybdenum on the growth, quality and yield of amaranth

0.67 ml/L, 1.00 mlL/L and 2.00 mL/L of molybdenum fertilizer was sprayed on the leaves of amaranth (Amaranthus mangostanus L.). Growth and quality of amaranth was studied on molybdenum fertilizer. The results showed that suitable concentration of molybdenum fertilizer could promote the growth, improve the content of chlorophyll, increase amaranth production, improve the quality and decrease the accumulation of nitrates in the leaves of amaranth. However, the effect was different during different period. 1.00 ml/L of molybdenum fertilizer had the best effect.
