Influence of Bradyrhizobium and Mycorrhiza on Growth, Yield and Phosphorus Use Efficiency on Soybean under Manure Application
Journal Title: Journal of Advances in Microbiology - Year 2017, Vol 3, Issue 3
Abstract
A field experiment was conducted at the Federal University of Agriculture, Abeokuta, South West Nigeria, to determine the influence of Bradyrhizobium and mycorrhiza on growth, yield and phosphorus use efficiency of soybean (Glycine max L.) under manure application. The treatments consisted of three factors, Bradyrhizobium (with or without), Phosphorus source (Single super phosphate) and poultry manure (0, 5, 10 ton/ha). The variety of soybean worked on was TX 1448-2E. The influence of these treatments on plant height shows, poultry manure of 0, 5 and 10 ton/ha had no significant difference at 4 – 12 week after planting (WAP) but at 14 WAP plots which received 0 ton/ha had highest values. Also, for Phosphorus source, they shows no differences at 6 WAP while at 4, 8, 10, 12 and 14 WAP plants that received mycorrhiza shows a greater influence on the plant height. Plot with Bradyrhizobium show no differences at 4 and 14 WAP. The application of mycorrhiza as a P source had great influence on soybean production under manure application. Also, the use of poultry manure had an influence on soybean at 5-10 ton/ha. Similarly, on Phosphorus use efficiency, the application of the treatments shows significant differences at 6 WAP where plots that received mycorrhiza with 10 ton/ha of poultry manure showed higher values at p <0.05. However, there were no significant differences on the treatments at 8 WAP, but plots that received Bradyrhizobium, mycorrhiza with 10 tons of poultry manure showed higher values at p<0.05.
