| ABSTRACT Plant growth-promoting bacteria (PGPB) comprise part of plant microbiome of biotechnological interest due to their potential to decrease the use of agrochemicals in agriculture. Among the commonly found PGPB species, the Pseudomonas genus is known for high competitiveness and efficiency in expressing growth-promotion traits. To increase the contribution of diazotrophic Pseudomonas sp. to the plant nitrogen nutrition, the strain AZM-01 was chemically mutagenized with methyl methanesulfonate (MMS), following the selection for resistance to ethylenediamine (EDA). From the 13 EDA-resistant mutant strains selected, four showed increased the ammonium excretion, with the highest value reaching up to 284% increase as compared to the wild strain, and six... |

| Integrated nutrient management is a major agronomic practice which brings together all methods to support plants nutritional requirement. However, the interaction of these methods together is very complex and needs to be studied in different climatic conditions. So, the effect of nitrogen fertilizer and Azospirillum lipoferum inoculation on maize (Zea mays L.) growth, yield and nutrients uptake was determined in this study. The hypothesis was that the bacterial inoculation decreases the need for N fertilizer application without reducing plant yield. Therefore, we carried out a factorial experiment in a randomized complete block design with three replications. Nitrogen at 0, 25, 50, 75 and 100 % concentrations of the recommended dose, i.e. 150 kg N ha-1... |

| ABSTRACT There is a worldwide concern regarding the management of agroindustrial residues, involving sustainable practices that contribute to taking advantage of the residues as inputs in productive processes, allowing greater efficiency in the integration of agricultural activities and mitigating their adverse effects on the soil. Therefore, the objective of this study was to assess the effects of application of cassava wastewater on the chemical attributes of the soil cultivated with Brachiaria brizantha cv. Marandu. The experimental design was in randomized blocks with five treatments (0, 15, 30, 60 and 120 m³ ha-1 of cassava wastewater) and four repetitions. To characterize soil chemical attributes soil samples were collected at depths 0 to 10 and 10... |

| Durante el temporal de 2009, se realizó un estudio de campo en Cocula, Gro. (clima cálido) y Montecillo, Méx. (clima templado) en una variedad de frijol chino (Vigna unguiculata (L.) Walp) de crecimiento indeterminado. Se evaluó el rendimiento de grano, biomasa total, índices de crecimiento, eficiencia en el uso del agua y rentabilidad económica en espaldera convencional (FS), espaldera de maíz (FM) y girasol (FG), con y sin biofertilizantes. Se registró la temperatura máxima y mínima, cantidad de lluvia y evaporación. La producción de vaina verde solo se evaluó en clima cálido en función del tipo de espaldera. El diseño experimental fue de bloques completos al azar con cuatro repeticiones. El ciclo del cultivo se acortó en 25 días en clima cálido (125... |

| ABSTRACT Biopower is a commercial rice biofertilizer comprised of various associative nitrogen fixers. In this present study, a field trial was carried out to assess the effects of Biopower application on the growth of some rice weeds and yield of rice (Oryza sativa). Four common rice weeds namely Cyperus rotundus, Echinochloa colonum, Marsilea minuta, Paspalum paspaloides, and mixed weeds were sown in 1:1 weed crop ratio in soil amended with i) ½ dose of N (nitrogen) + recommended doses of PK (phosphorus, potassium) fertilizers, ii) recommended doses of NPK fertilizers, and iii) farmyard manure (FYM) + ¼NPK fertilizers, with and without Biopower application. Biopower application variably reduced weed biomass in different soil amendment systems. The effect... |

| ABSTRACT High-throughput phenotyping using spectral reflectance measurements offers the potential to provide more information for making better-informed management decisions at the crop canopy level in real time. The aim of this study was to investigate the suitability of hyperspectral reflectance measurements of the crop canopy for the assessment of biomass, nitrogen concentration, nitrogen uptake, relative chlorophyll contents, and yield in 2 peanut cultivars, Giza 5 and Giza 6. Peanuts were grown under field conditions and subjected to 3 doses of nitrogen fertilizer with or without the application of 2 bio-fertilizers, Bradyrhizobium spp. or plant growth-promoting rhizobacteria. Simple linear regression of normalized difference spectral indices and... |

| ABSTRACTThe reduction on crop production observed in semiarid conditions is closely linked to soils degradation in their physical, microbiological and fertility aspects. Based on this premise, the effects of different types of organic fertilizers associated to the use of mulching in the production of cowpea grown in Paraíba state, Brazil, under semiarid conditions, was studied. The research was conducted under field conditions in the municipality of Casserengue, PB, from April to July 2010. The statistical design in randomized block design with five treatments and five replicates was used, totaling 25 experimental units. Treatments consisted on application of cattle manure or biofertilizer on presence or absence of mulch, plus a control treatment, without... |

| The impact of pig slurry and poultry litter fertilization on soils depends on the conditions of use and the amounts applied. This study evaluated the effect of organic fertilizers after different application periods in different areas on the physical properties and organic carbon contents of a Rhodic Kandiudox, in Concordia, Santa Catarina, in Southern Brazil. The treatments consisted of different land uses and periods of pig and poultry litter fertilization: silage maize (M7 years), silage maize (M20 years), annual ryegrass pasture (P3 years), annual ryegrass pasture (P15 years), perennial pasture (PP20 years), yerba mate tea (Mt20 years), native forest (NF), and native pasture without manure application (P0). The 0-5, 5-10 and 10-20 cm soil layers were... |

| ABSTRACT Sesame is an oilseed that has low demand of water; it is widely grown in tropical regions, but few studies had been conducted on its mineral nutrition. The objective of this study was to evaluate physiological and production variables of two sesame genotypes (BRS-Seda and Preto) varying the organomineral fertilizer doses, via fertigation. The genotypes were grown under field conditions during the 2014/2015 dry season, in an agricultural area in Lagoa Seca, PB, Brazil. The two genotypes were subjected to five doses (0, 30, 60, 90 and 120% of the nutritional requirement of the crop) of an organomineral fertilizer based on sugarcane vinasse, and to an additional treatment consisting of mineral fertilizer (100% of the crop requirement). The experiment... |

| The use of cow urine can be considered an agricultural practice of low cost for farmers. Nevertheless, its efficiency on crop needs research information. The present research aimed to evaluate the effect of cow urine on the growth and yield of 'Regina 2000' lettuce, in an experiment carried out from January 13, 2006 to March 22, 2006. The experiment was set up with 12 treatments, in a split-plot design and four completely randomized blocks. The soil and leaf applications were installed in the plot. In the split-plot, cow urine was applied at different concentrations (0.00; 0.25; 0.50; 0.75; 1.00 and 1.25 %). The plot presented four rows with 1.75 m each, in 0.25 x 0.25 m spacing. The six central plants of the two central rows formed the sampled split-plot.... |

| ABSTRACT The growing demand for animal protein is directly related to the feedlot system of animals and their assumptions, such as the waste management. The characterization of the final products becomes an important factor in decision making by one or by other process. The objective was highlight characteristics that fertilizers present due to the used of stabilization process, by the principal component analysis. For the manure stabilization we realized three aerobic processes, composting, vermicomposting and natural decomposition, and one anaerobic, the anaerobic digestion. These processes produced the compost, the vermicompost, the decomposed manure and the biofertilizer. Fertilizers produced were analyzed by means of seventeen chemical and... |
