Exploring new source of organic manure for fertilizer micro dose technology response of cereals to different source of micro-dose fertilizer

  1. The micro-dosing fertilizer application technology was designed for small and medium scale farmers to maximize the effect of small quan- tity of available organic and inorganic fertilizers. While the technology presently rely on ruminants manure as the organic source, poultry production is on the rise and expected to generate significant quantity of organic manure. This gives opportunity to use poultry manure in micro-dose technology. It is generally believed that poultry manure is higher in nutrient than ruminant manure. This may increase its po- tential as a source of organic fertilizer for the micro-dosing technology. It is necessary to evaluate the poultry manure in combination with other organic and inorganic fertilizers. • baCkground • To identify the effect of different rates and sources of organic ma- nure and combination with synthetic fertilizer on the growth and yield of cereals • To assess the effectiveness in terms of nutrients supply to the soil from both organic and inorganic manures. • objeCtives Eight Micro-dosing fertilizer treatments were tested with two controls of no fertilizer and the blanket recommendation of NPK 80:60:60 using millet and sorghum as test crops. The trial was planted in two locations in the Sudan savanna zone of Nigeria. • metHodology On-farm trial demonstrating the effect of the selected microdosing treatments covering over 600 farmers in 4 States of Northern Nigeria. Each farmer compared 2 microdose treatment with a control which was either a no fertilizer or an NPK 80:60:60 application. • aCtivities Millet: While there was no significant differences among the micro- dose treatments in the relatively higher fertile soil of Minjibir, there were significant differences in the relatively low fertile soil of Gam- bawa. Micro-dose with 150 gm poultry manure/hill produced highest grain yield (793 kg/ha) followed by 100 gm poultry manure/hill (743 kg/ha) while control (no fertilizer) produced the lowest yield (188 kg/ha). Sorghum: The response of sorghum was slightly different from the response of millet. Full application of NPK at 80:60:60 produced hi- ghest grain yields (1706 kg/ha) followed by NPK 15 plus cow manure 100 gm/hill (1685 kg/ha). • results and main aCHievements • Current and PartnersHis future engagements for out sCaling Poultry manure present a complimentary source of organic manure for use in the fertilizer micro-dose technology for small and medium scale farmers in the dry savannas of west Africa. The effect of the poultry manure is more feasible and significant under the low fertility conditions common among these farmers. • ConClusions The best treatments are undergoing farmer participatory testing and would be upscale through the ATASP-1 projects in 4 States in the Sudan Savanna zone of Nigeria.
