Abstract
The effects of poultry manure from different sources were evaluated in two growing seasons on the growth parameters and marketable yield of leaf amaranth (Amaranthus cruentus (hybridus) L) Amaranthaceae in a field experiment conducted on a slightly acid sandy loam Oxic Tropudalf at the Teaching and Research Farm, University of Ado-Ekiti. The treatments consisted of 10, 20 and 30 metric tonnes (MT) /ha each of manure collected from turkey, layer and broiler pens, and a control ( 0 MT/ha ) in four replications. Plant height, leaf length, number of leaves, stem girth and marketable yield were measured at 5, 6 and 7 weeks after sowing. Plant height, number of leaves and leaf area increased with the application of poultry manure from the different sources. The application of 30 MT/ha rate of manure from broiler and layers significantly (P<0.05) produced the highest number of leaves, plant height and marketable yield.
