Abstract
Celosia (Celosia argentea) are annuals, used as both ornamental and vegetables, that are well adapted to difficult soil conditions, nutrient deficiencies, and hot weather. In Nigeria, celosia is used as a vegetable, providing a significant source of dietary nutrients. However, soil Zn levels are typically low and result in dietary deficiencies as well. Therefore, the purpose of this study was to evaluate celosia growth across various Zn fertilizer levels. This study evaluated the effect of Zn fertilizer (ZnSO4) at 0, 50, 100, and 150 ppm Zn on growth and leaf nutrient content in celosia. Sixteen celosia plants were planted in the greenhouse at Texas A&M University - Commerce. Plants were arranged in a randomized complete block design, with four blocks and each fertilizer treatment level appearing once in each block. Zn fertilized plants were taller and had higher root fresh weights, but no differences in other physical measures. Potassium, magnesium, and Zn nutrients were significantly higher in Zn fertilized leaves; nitrogen, potassium, magnesium, and sodium were significantly higher in roots. Zn fertilization improved plant growth and nutrition, but these benefits disappeared at levels above 100 ppm Zn.
