dc.description.abstractA field experiment was conducted during the wet and dry seasons of 1987 at Samaru, Zaria in northern Guinea Savanna of Nigeria to study the effects of nitrogen and plant population en the growth and yield of vegetable amaranth (Amaranthus cruentus, L.). The treatments consisted of four N levels (0.0, 45.0, 90.0 and 180.0 kg N/ha) and five plant populations (9, 16, 25, 49 and 100 plants/m ) laid out in a randomized complete block design with four replications. Nitrogen application increased plant height, leaf area, shoot dry weight and length of harvested branches significantly over the control. Application of 180 kg N/ha increased marketable, edible and total dry matter yield by 19.5, 20.0 and 17.8 percent, respectively over the control. Percent protein content of the edible yield was significantly increased by N application. Number of leaves, leaf area, shoot dry weight, number and length of harvested branches per plant as well as percent stand court at harvest were significantly decreased by increase in plant population. Plant height however, increased significantly with increase in plant population. Marketable, edible and total dry matter yields of vegetable amaranth increased significantly with increase in plant population. In terms of marketable, edible and total dry matter yields, the dry season crop out-yielded the wet season crop by 59.0, 58.8 and 58.1, respectivelyen_US
