The main effect of poultry manure on soil physico-chemical properties, leaf nutrients contents and yield of yam (Dioscorea rotundata) was investigated in a factorial experiment involving tillage at five levels- ploughing, ploughing plus harrowing, manual ridging, manual heaping and zero-tillage; poultry manure at 0 t/ha and 10 t/ha laid out in a split-plot design at two locations in Ondo, Nigeria. The data obtained indicated that poultry manure application improved soil physical properties; it reduced soil bulk density, temperature and also increased total porosity and soil moisture retention capacity. It also, improved soil organic matter, total N, available P, exchangeable Mg, Ca, K and lowered exchange acidity. It also increased nutrient uptake, growth and yield of yam significantly. The use of poultry manure in crop production is recommended as it will ensure stability of soil structure; improve soil organic matter status, nutrients availability and high crop yield.

Effect of Poultry Manure on Soil Physico-Chemical Properties, Leaf Nutrient Contents and Yield of Yam (Dioscorea rotundata) on Alfisol in Southwestern Nigeria.

A pot experiment was conducted to compare different organic manures with NPK fertilizer for improvement of chemical properties of acid soil from farmer’s field in coastal area of Epe and nutrient depleted soil from research field of Institute of Agricultural Research and Training, Moor Plantation, Ibadan. Maize was planted for 12 weeks and dry matter yield was determined. Results showed that application of 5 ton/ha of each of the evaluated organic manures and 100 kg/ha NPK 15-15-15 fertilizer improved chemical properties of both acid and nutrient depleted soils compared with unfertilized soil. Application of different types of organic manures reduced the acidic levels of both the soils. Cow dung application resulted in the highest pH levels of 6.37 and 6.50 in acid soil and nutrient depleted soil respectively while NPK fertilizer gave lowest pH levels of 5.28 and 5.74 for both soils. Also, application of different types of organic manures enhanced soil organic C, total N, available P, exchangeable K and CEC better than NPK fertilizer in both soils. The study indicated that among the organic manures evaluated, cane rat droppings improved soil chemical properties best. Plant dry matter yield increased with application of NPK fertilizer compared with compost, poultry manure and cane rat droppings in both soils. In acid soil, application of NPK fertilizer gave the highest dry matter yield of 4.77 g/plant while in nutrient depleted soil; application of NPK fertilizer gave the highest dry matter yield of 5.58 g/plant.

Comparative study of different organic manures and NPK fertilizer for improvement of soil chemical properties and dry matter yield of maize in two different soils

A field study was conducted on the separate and combined effect of two agrowastes namely:Cocoa pod ash and poultry manure on soil fertility, nutrient content, growth and grain yield of maize on an Alfisol in Southwest Nigeria. Separate and combined effects of the materials were investigated at application rates of 0, 5 and 10t/ha given nine treatments. The effect of treatments on the first crop and residual effect on the second crop was studied. The test soil was low in organic matter (OM), N, P, K, Ca and Zn. Poultry manure had lower C:N ratio and higher N, P, Mg, Fe and Mn concentrations compared with cocoa pod ash which had higher K and Ca concentrations. Cocoa pod ash and poultry manure increased significantly soil OM, soil and maize macro and micro nutrients content on immediate and residual basis. The two materials have cumulative and complementary effect on soil nutrients and nutrient uptake. While poultry manure gave higher values of soil N, P, Ca and Mg and plant N, P, Zn, Fe, Cu and Mn than cocoa pod ash, ash gave higher values of soil Cu, Zn, and Mn and plant K and Ca. Plant N, P, K, Zn and Fe increased with level of poultry manure. The ash and poultry manure increased dry matter yield, height and grain yield of maize significantly, although poultry manure gave higher yield than ash at the same rate. The ash at 5 and 10t/ha increased grain yield by 20 and 31% respectively on immediate basis and by 34 and 74% on residual basis. Poultry manure at 5 and 10t/ha increased yield by 39 and 43% respectively on immediate basis, and 73 and 93% on residual basis. Combination of 5t/ha cocoa pod ash with poultry manure at 10 and 5t/ha respectively gave highest cumulative yield of 6.51 and 5.58t/ha.

Field experiments were conducted at the Teaching and Research Farm of the Faculty of Agriculture and Natural Resources Management, Ebonyi State University, Abakaliki, southeastern Nigeria, in 2008, 2009, and 2010, to study the selected physico-chemical properties of an ultisol and maize yield (Zea mays L.) as influenced by application of rice husk dust in 2008 and 2009 and the residual effect in 2010. Soil bulk density, total porosity, moisture content, soil organic carbon, total nitrogen, C:N ratio, pH, and available phosphorus and exchangeable bases were all significantly affected by amendment with rice husk dust at the rates of 10 and 20 t ha− 1. In general, bulk density, total porosity, soil water content, organic carbon, and C:N were more affected by unburnt than burnt waste, while the reverse was true for pH, available phosphorus, and exchangeable K+ and Ca2+. Application of rice husk dust resulted in increased maize grain yields during the two seasons when it was applied and as a residual effect in...

Identification of a sustainable integrated soil fertility management option in the tropics will not only salvage the degraded soils but also enhances the attainment of the goal of food security. This study was conducted in 2004 and 2005 on a degraded tropical Alfisol in south western Nigeria to evaluate the effect of legume residue, poultry manure and inorganic fertilizers on maize yield, nutrient uptake and soil properties. The treatments consisted of two rates of poultry manure (0 and 5 t ha−1), three rates of N fertilizer (0, 50 and 100 kg N ha−1 applied as urea), three rates of P fertilizer (0, 30 and 60 kg P ha−1 applied as single super phosphate) and two soybean treatments (with or without incorporation of legume residue) in various combinations as a factorial experiment in Randomized Complete Block design with three replicates. Results showed that poultry manure alone led to significant increase in maize yield (60%) and soil organic matter (45%). In contrast, legume residue incorporation gave significantly lower increase in yield (7%) and soil organic matter (11%). However, the combined application of poultry manure and legume incorporation led to 72% increase in maize yield as opposed to 63 and 10% increase recorded when manure alone or legume alone were incorporated, respectively. Optimal maize yield was achieved when manure application was integrated with P fertilizer application. The interaction of P fertilizer and legume incorporation indicated that soil phosphorus and maize P concentration were significantly increased with the application of the P fertilizer and legume incorporation. Hence, the application of P fertilizer alone is most likely to be economical compared with its integration with legume incorporation.

The comparative effectiveness of residual effects of 300 kg/ha NPK 15-15-15 fertilizer, 7t/ha poultry manure (Pm), five combinations of reduced levels of NPK 15-15-15 fertilizer and poultry manure, and control (no fertilizer) on soil and plant nutrient uptake and maize yield were investigated in a field trial during the 1996 and 1997 second cropping seasons at the Teaching and Research Farm of the Federal University of Technology, Akure (7o 16” N, 5 o 12”E), Nigeria. The soil type of the trial site was lowly fertile loamy sand. Application of poultry manure, and combinations of poultry manure with NPK fertilizer gave high residual effects on soil chemical composition and increased plant height, leaf area, dry matter yield, plant nutrient uptake and grain yield of maize significantly. Residual effects of poultry manure, and combined application of reduced quantities of poultry manure and NPK fertilizer gave higher soil organic matter, N, P, K, Ca, Mg and micro-elements contents compared to application of 300 kg/ha NPK 15-15-15 fertilizer and control. The residual effects of 3t/ha poultry manure plus 200kg/ha NPK fertilizer and 7t/ha poultry manure produced non-significantly different values. However, the 7t/ha poultry manure had the best residual effects on maize yield and soil fertility. The 3t/ha poultry manure plus 200kg/ha NPK fertilizer is recommended as substitute for 7t/ha poultry manure or 300kg/ha NPK fertilizer.
