to determine the effects of different sowing media on emergence and growth of moringa (Moringa oleifera Lam) seedlings in the nursery. The moringa seeds used for the study were collected from different parts of Nigeria; Nsukka (Eastern Nigeria), Ibadan (Western Nigeria) and Jos (Northern Nigeria). The sowing media were weathered sawdust (100%), top soil (100%), weathered sawdust plus cured poultry manure in the ratio of 2:1(volume by volume; v/v), and top soil plus cured poultry manure plus river sand in the ratio of 3:2:1(v/v/v). Perforated black polythene bags were used as potting media. The experiment was a 3 x 4 factorial trial in completely randomized design with three replications. The seeds sown in the 100% topsoil took average of 8.2
The study was carried out in the University of Nigeria, Nsukka, Nigeria from 2010 to 2011 to assess the effect of poultry manure application on growth and performance of potted moringa (Moringa oleifera Lam) plants raised for urban dwellers' use. Application of 5 and 10 t haG 1 of poultry manure to the soil medium ensured consistent increase in the plant height, stem girth, internode length, number of leaves and branches. The control treatment (0 t haG 1 ) had the least values of all the morphological characteristics. The 10 t haG 1 poultry manure treatment gave significant increase (p<0.05) in the plant growth vigour in the first two months of growth with a decrease in the third month. There were significant accession by poultry manure interaction effects (p<0.05) in the days to initial, 50% flowering and fresh leaf biomass production/plant and none in the days to 100% flowering, days to pod formation, number of pods/plant, number of seeds/pod, pod length and pod circumference. The 10 t haG 1 poultry manure gave the highest values of all the yield traits in 2011 followed by 5 and 0 t haG 1 , respectively. There were significant accession by manure interaction effects (p<0.05) on all the yield traits except days to first and 50% flowering. There were lesser days to first, 50, 100% flowering and pod formation and higher values of all the other yield traits in 2011 than in 2010.
<p>The pod and yield characteristics of <em>Moringa oleifera </em>plants grown in Ibadan (Rainforest vegetation), Nsukka (Forest-derived savannah vegetation) and Jos (arid derived savannah vegetation) were evaluated from 2007- 2009 to assess adaptability of the plant to climate change threats. The rainfall and temperature distribution in the three locations varied over the years. The <em>Moringa oleifera</em> plants grown at Ibadan had the greatest pod and seed yield followed by those at Nsukka and Jos in that order. The annual pod and seed production capacities of the plants differed significantly (p < 0.05) in the different locations. The overall annual pod and seed production per location, including yield characteristics, did not differ significantly throughout the years of study. <em>Moringa oleifera</em> was therefore found to be a suitable crop adaptable to various environmental and climatic changes in Nigeria.</p>
