Assessment of the Responsiveness of Soybean Varieties to Bradyrhizobium Japonicum Inoculation in Ogbomoso, Southwest Nigeria

Olaboopo, M. T.^*

Soybean varieties may respond differently to rhizobium inoculation, for im- proved yield and nitrogen fixation. Therefore, responses of ten soybean varieties to rhizobium were evaluated in 2018 at the Ladoke Akintola University of Tech- nology, Ogbomoso, Nigeria, to determine if rhizobium will improve the perfor- mance of the varieties. The soybean varieties (main plot) and rhizobium (+ or -, subp...

Influence of Soil Amendment with Poultry Droppings on the Soil Properties and Productivity of Cucumbers (cucumis Sativus L.) on a Degraded Ultisol in Nsukka Area, Southeast Nigeria

Okebalama C.B^*, Ogunezi K.C, Agbo I.C, Asogwa K C

Poultry manure (PM) input is globally utilized for enhancing and maintaining soil fertility in vegetable farming. In many tropical regions, however, ‘site’ specific PM rate for optimum crop yield is lacking. A three-year continuous cucumber cultivation with 0, 10, 20 and 30 t/ha PM rates in three replicates, were arranged in RCBD on an Ultisol. Soil physicochemical properties and cucumber yield re...
