چکیده
Abstract: The objective of this work was to evaluate the response BRS Tumucumaque cowpea (Vigna unguiculata) cultivar liming and phosphorus potassium fertilization in absence inoculation or nitrogen fertilization, as well with selected Bradyrhizobium strains, an upland forest area state Amapá, eastern Amazon, Brazil. Seven experiments were conducted field conditions, order six limestone, four phosphorus, rates, besides strains. Leaf concentrations, pod grain dry mass per plant, yield, soil pH, Al+3, Ca+2 + Mg+2 evaluated. obtained data subjected analysis variance, regression analysis, test compare means. presented a high buffer power, but reduced its chemical limitations. concentrations correlated yield. However, there is no effect interaction between rates on In addition, yield not influenced by increased fertilization. Inoculation UFLA 3-84 INPA 03-11B strains promotes greater than that BR 3262 3267, similar control without inoculation.

Growth and Yield Responses of Cowpea to Inoculation and Phosphorus Fertilization in Different Environments
Cowpea (Vigna unguiculata) is a major source of dietary protein and essential component of the cropping systems in semi-arid regions of Sub-Saharan Africa. However, yields are very low due to lack of improved cultivars, poor management practices, and limited inputs use. The objectives of this study were to assess the effects of rhizobia inoculant and P on nodulation, N accumulation and yield of...

The aim of this work was to characterize rhizobia isolated from the root nodules of cowpea (Vigna unguiculata) plants cultivated in Amazon soils samples by means of ARDRA (Amplified rDNA Restriction Analysis) and sequencing analysis, to know their phylogenetic relationships. The 16S rRNA gene of rhizobia was amplified by PCR (polymerase chain reaction) using universal primers Y1 and Y3. The amp...

Forest liming increases forest floor carbon and nitrogen stocks in a mixed hardwood forest.
In acid-impacted forests, decreased soil pH and calcium (Ca) availability have the potential to influence biotic and abiotic controls on carbon (C) and nitrogen (N) cycling. We investigated the effects of liming on above- and belowground C and N pools and fluxes 19 years after lime addition to the Woods Lake Watershed, Adirondack Park, New York, USA. Soil pH and exchangeable Ca remained elevate...
