In order to be used in a program of inoculation, efficient arbuscular mycorrhizal fungi (AMF) must be able to cope with the indigeneous fungal population. An experiment was conducted under greenhouse conditions at the Embrapa Cassava and Fruit Crops in Cruz das Almas (BA), Brazil, with the objective to evaluate the competitive capability of selected fungi, using natural soil with Tainung no. 1 variety. A Yellow Oxisol with 3 mg dm-3 of available P was used. Three exotic and three […]

Soybean [Glycine max (L.) Merrill] inoculation and reinoculation are essential to guarantee the maximization of the biological N2 fixation process. Most inoculants commercialized for soybean in Brazil are peat-based, but there are doubts about the dose of peat inoculant which should be recommended, specially under stressing conditions or in areas previously inoculated. Therefore, for the central region of Brazil, the recommendation is 1.000 g of inoculant/50 kg of seeds, with a sugar cane solution as adhesive. However, in this study […]
