Vegetable Amaranth (A. cruentus) is a promising C4 crop for semi- arid regions due to its nutritive value, medicinal property and ornamental for beautifying gardens . It is widely grown in the tropics and is one of the most important leafy vegetables in the lowlands of Africa, South America and Asia. Little knowledge is known on its Nitrogen requirement, that is why this experiment was conducted to fill in that gap. A field study was conducted in Nyanga which is a high rainfall area receiving over 1000 mm/ annum. The vegetable was sown in the cropping season of 2014/15 to determine the effect of different nitrogen fertilizer levels on (0, 50, 100, 150kg/ha and 200 kg/ha on the growth and yield parameters which were, days to 50 % flowering, dry weight (kg/ha), seed yield (kg/ha) and fresh leaf weight (kg/ha). There was significant difference (p
