The research work conducted at the Teaching and Research Farm of University of Abuja was aimed at assessing the effect of Moringa oleifera, selected leguminous plants and inorganic fertilizer on the performance of orange fleshed sweet potato in Alley Cropping System. while plots in which NPK fertilizer was applied experienced highest weed dry matter (4.083g/m 2 ) although highest root yield (1.2t/ha) was recorded from the plots with NPK fertilizer.
piggery waste management, profitability, pig farming, net profit The pig is a major component of livestock especially in Southeastern Nigeria where there are no cultural or religious inhibitions to the production and consumption of pork. The potentialities of pig as an effective provider of protein for human diet have well been recognized (Odo 2000). The relative advantages of the pig in respect of this include its high survival rate and ability to utilize a host of agro industrial bye products and crop residue (Fetuga 1997; Ter meulen and El-Hanth 1985; Twrnamasiko 2001) with little or no processing and at minimal cost (Tewe and Adesehinwa 1995). Pigs are known to be prolific producers, realizing 20-30 piglets from 2 to 3 litters per year (Adesehinwa 2003), with short generation intervals.
The study evaluated the effect of Moringa oleifera based agro-forestry system on Sweet potato yields in North Central Nigeria.. The study was carried out in the Potato Multiplication Centre in Gikwoyi, Federal Capital Territory, Abuja. Randomized Complete Block Design with 3 replications was used. Data collected included, soil physico-chemical properties, aerial biomass weight, tuber yield, and weed biomass weight. Performance of Ipomea batata was significantly improved by Moringa oleifera based agro-forestry systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
