Amaranthus is a relatively new and underutilized crop that has developed from being a weed to a vegetable in many developing countries. However, its commercialization has been hampered by limited agronomic guidelines that will facilitate large scale production of the vegetable. A field experiment was conducted at Horticultural Research Centre in Marondera, Zimbabwe to investigate the response of Amarunthus cruentus to organic and inorganic fertilizer. The trial was laid out in a randomized complete block design with eight treatments replicated three times. The treatments used were 0 (control), 10, 15, 20t/ha cattle manure and four levels of inorganic fertilizers 100, 200, 300, 400kg/ha NPK (7:14:7). Significant differences (P<0.05) were observed with respect to germination percentage, fresh yield, number of shoots, stem girth and plant height. All the inorganic fertilizer treatments outperformed the organic fertilizer in all parameters assessed. Further research is recommended to determine the appropriate rates of organic fertilizers for optimum performance.
