“…The cultural practices were carried out according to CTCo protocol. Composite sample of soil was collected at 20 cm depth, to characterize the chemical and physical properties (Table 1), according to the methodology described by Souza et al, 2011. The rainfall during the experiment was 1,042 mm.…”

The staple diet of most of the world population is provided by cereal, which present levels of iron (Fe) and zinc (Zn) below the nutritional demand of humans. Other factors that may substantially interfere for the low intake of Fe and Zn are the anti- nutritional factors present in the edible parts of plants, such as heavy metals and phytate. Hence, the objective of this study was to evaluate the genotypic variation in terms of yield (kg ha-1), plant height, insertion height of first pod, as well as concentrations of Fe, Zn, phosphorus (P) and the anti-nutrient phytate in grains of 24 soybean cultivars and to identify cultivars with potential for biofortification. The field experiment was conducted in Rio Verde, state of Goiás by the technological center of COMIGO. The experimental design used in the study was a randomized block design with 24 treatments and three replications. The results showed that there is genotypic variation for grain yield (kg ha-1), plant height, and insertion height of first pod, as well as for the concentrations of Zn, Fe, P and concentration of anti-nutient phytate in grains among the soybean cultivars. Non-significant or low correlations were found among the evaluated parameters except for the relationship between P and phytate (r=0.733). The diversity found among soybean cultivars offers genotypes such as 8197RR, M 7908RR and BRS 262 with potential to develop cultivars with better ability to accumulate nutrients in grains.

“…Surface soil (0-20 cm depth) was collected from a non-cultivated field with natural Brazilian Cerrado vegetation. Later, after sieving through 4-mm mesh sieve, soil subsamples were characterized chemically, physically and mineralogically (Table 1), using the same methodology described in Souza et al (2011).…”

The effects of foliar and soil applied phosphite on grain yield in common bean (Phaseolus vulgaris L.) grown in a weathered soil under low and adequate phosphate availability were evaluated. In the first experiment, treatments were composed of a 2 x 7 + 2 factorial scheme, with 2 soil P levels supplied as phosphate (40 e 200 mg P dm -3 soil), 7 soil P levels supplied as phosphite (0-100 mg P dm -3 soil), and 2 additional treatments (without P supply in soil, and all P supplied as phosphite). In the second experiment, treatments were composed of a 2 x 3 x 2 factorial scheme, with 2 soil phosphate levels (40 e 200 mg P dm -3 soil), combined with 3 nutrient sources applied via foliar sprays (potassium phosphite, potassium phosphate, and potassium chloride as a control), and 2 foliar application numbers (single and two application). Additional treatments showed that phosphite is not P source for common bean nutrition. Phosphite supply in soil increased the P content in shoot (at full physiological maturity stage) and grains, but at the same time considerably decreased grain yield, regardless of the soil phosphate availability. Foliar sprays of phosphite decreased grain yield in plants grown under low soil phosphate availability, but no effect was observed in plants grown under adequate soil phosphate availability. In general, foliar sprays of phosphate did not satisfactorily improve grain yield of the common bean plants grown under low soil phosphate availability. Index terms:Phaseolus vulgaris, tropical soil, foliar fertilizer, plant nutrition. RESUMOOs efeitos de fosfito aplicado via solo ou foliar sobre produção de grãos em feijoeiro (Phaseolus vulgaris L.), cultivado em um solo intemperizado sob baixa ou adequada disponibilidade de fosfato foram avaliados. No primeiro experimento, o delineamento consistiu de um esquema fatorial 2 x 7 + 2, sendo 2 doses de P fornecidas na forma de fosfato (40 e 200 mg P dm -3 de solo) x 7 doses de P no solo fornecidas na forma de fosfito (0-100 mg P dm -3 de solo), mais 2 tratamentos adicionais (sem fornecimento de P no solo, e todo o P fornecido na forma de fosfito). No segundo experimento, o delineamento consistiu de um esquema fatorial 2 x 3 x 2, com 2 doses de P no solo na forma de fosfato (40 e 200 mg P dm -3 de solo), combinados com 3 fontes de nutrientes aplicados via pulverização foliar (fosfito de potássio, fosfato de potássio, e cloreto de potássio como um controle), e 2 números de aplicações foliares (uma e duas aplicações). Os tratamentos adicionais evidenciaram que o fosfito não é uma fonte de P para a nutrição do feijoeiro. O fornecimento de fosfito no solo aumentou o teor de P na parte aérea (no estágio de maturidade fisiológica) e nos grãos, mas, ao mesmo tempo, consideravelmente reduziu a produção de grãos, independentemente da disponibilidade de fosfato no solo. As pulverizações foliares de fosfito diminuiram a produção de grãos em plantas cultivadas com baixa disponibilidade de fosfato no solo, mas esse efeito não foi observado em plantas cultivadas com...

“…Therefore, for the proper development of the plants it is necessary to correct the soil. Lime application has been the main method for acidity correction because of its low cost, facility of application and increase of plant availability of Ca and Mg (Souza et al, 2011). However, in spite of being the most used corrective, the limestone has low mobility in the soil profile, slowing down the correction beyond the incorporation layer.…”

“…As a result of these benefits, silicates have been tested for use in acidity correction (Ramos et al, 2006) with the advantage of providing silicon to plants (Barbosa et al, 2008). Souza et al (2011) evaluated the effect of the substitution of calcium carbonate by calcium silicate on the palisade grass cultivated in soils with different textures and mineralogical composition. The authors found that the biomass production and feed quality of the palisade grass were generally higher with the 50% calcium silicate treatment.…”

The correction of soil acidity and the evaluation of the effects of correctives used are not frequent practices in pasture areas. The benefits of silicon on the physiology and biochemistry of pastures is a subject that has not been explored in great detail. The objective of this study was to evaluate the performance of Urochloa brizantha plants (cultivar Xaraés) submited to condictions of water deficity and silicate fertilization through physiological and biochemical parameters. The experiment was carried out in pots under greenhouse conditions..The experimental design was randomized blocks, in a 2 × 2 factorial arrangement, with eight replications. The treatments consisted of a combination of the presence and absence of silicon (by means of soil correction using agrosilicon and dolomitic limestone, to raise the base saturation to 50%) with 2 soil water conditions (40 and 80% of field capacity). The analyzes were performed to determine: net CO 2 assimilation rate, stomatal conductance, transpiration rate, water use efficiency, superoxide dismutase and catalase enzyme activities, shoot dry matter ,neutral detergent fiber and acid detergent fiber determinations and leave protein. The application of silicon in Urochloa brizantha cultivar Xaraés has the potential of attenuate the water deficity, increasing the photosynthesis, plant dry matter and antioxidant enzymes activity.
