Effects of Soil Texture and Nutrients Application On Soybean Nutrient Uptake, Growth and Yield Response

Soybean is a good source of protein and calories therefore important for food security. yields in small scale farmers field stand at less than 1.0 t ha-1 against potential 3 to 3.6 ha-1. This has been attributed low soil fertility. Although lot work carried out on nitrogen (N) phosphorus (P) nutrition, but research findings indicate that are still low, raising suspicion other nutrients could also be limiting. To investigate this, nutrient omission trial was used the greenhouse find limit soybean production four distinct textures - clay loam, sandy loam following recommended rate 20:40:20:5:20 Kg/ha N,P,K,Zn, S respectively. Similarly we applied 1 ton/ha poultry manure with thirty six treatments combinations arranged completely randomized design. The results revealed performance uptake varied significantly (p<0.05) between texture andnutrients application. Sandy respond nitrogen, phosphorus, potassium application whereas zinc NPK limits soils. In conclusion, increase Sudan savanna Nigeria, fertilizer formulations containing N, P, K Zn should used. Manure may improve together fertilizer.
