Field experiments were conducted at the University of Agriculture Makurdi and Cross River University of Technology Obubra, Nigeria during the 2009 and 2010 cropping seasons to evaluate the effect of Moringa oleifera leaves and poultry droppings on soil Nitrogen and yield of garden egg. A factorial combination of two varieties of garden egg (Gilo and Kumba) and organic manure (Moringa leaves) at 5, 10 and 20 t ha-1, poultry droppings at 5, 10 and 15 t ha- 1, respectively and a control (0 t h a-1 manure. These gave 14 treatment combinations, laid out in RCBD replicated thrice. Results obtained indicated that the manure increased soil N from 30 and 90 days. The highest increase in total N was obtained from Moringa leaf 20 t ha-1 and poultry droppings 15 t ha -1, while the control showed a decline in soil N. All manure rates significantly (P<0.05) increased the yield of the garden egg over the control. Poultry droppings at 15 t ha-1 produced the highest fruit yield (9.18 t ha -1 and 8.65 t ha-1) in 2009 and 11.87 t ha -1and 10.13 t ha -1 in 2010 for Makurdi and Obubra, respectively while the control produced least yield. The yields were significantly (P<0.05) higher in Makurdi than Obubra in both years and higher in 2010 in both locations. Poultry droppings (15 t ha-1) and Moringa leaf (20 t ha-1) as alternative therefore are good sources of nitrogen for the sustainable production of garden egg in these Nigerian agro-ecological locations.
