Soy has high plasticity, which expands its capacity to adapt to different environmental and management conditions, through morphological changes in production components. Thus, the objective was to evaluate the effects of different densities of soybean cultivar BRS 8381 on agronomic characteristics. The experiment was implemented and conducted in a Cerrado area, in the Agua Boa of Embrapa Roraima experimental field. A randomized block design was used in a 2*4 factorial scheme, with four replications. The treatments consisted of two years of soybean cultivation (2015 and 2016), sown in four plant densities (10, 14, 18 and 22 plants per linear meter). Agronomic characteristics were evaluated: plant height; height of insertion of the first pod; stem diameter; number of nodes on the stem; number of pods per plant; number of branches per plant; dry mass of the plant; harvest index and grain yield. The highest average productivity of 'BRS 8381' soybeans in the Cerrado area of Roraima is obtained with a population of 387.448 plants per hectare. 'BRS 8381' plants at density 22 plants m-1 linear are not suitable for the Cerrado conditions of Roraima. The cv. BRS 8381 is influenced by rainfall and temperature factors in the Cerrado conditions of Roraima.

Soybean (Glycine max L. Merrill) demand is high in Indonesia, however national production is low, therefore improving productivity is important. The research was aimed to determine the effect of application of biofertilizer containing N- fixing and P- solubilizing bacteria on the growth and production of soybean in lowland swamp. The experiment was conducted  at  Labuhan Ratu VI Village, District of Labuhan Ratu, East Lampung Regency from September to December 2014. The experiment was arranged in factorial randomized block design with three replications. N and P fertilizers were applied in four levels. Doses of N were 0, 11.25, 22.50, 33.75 kg ha-1, doses of P were 0, 36, 72, 108 P2O5 kg ha-1, in combination with and without biofertilizer application. The results showed that interaction between biofertilizer and N significantly affected number of branches and number of leaves at maximum vegetative phase. The influence of three types of fertilizer had no significant effect on the productivity of soybean in lowland swamp with soil pH of 7.0 and medium soil fertility. It is recommended to apply Biofertilizer + 11,25 kg N ha-1 + 36 kg P2O5 ha-1 to obtain high soybean production in lowland swamp area.<br /><br />Keywords: nitrogen, phosphate, productivity, soil fertility<br /><br />

The spatial arrangement and plant population have been highlighted as fundamental tools for increasing productivity. The objective was to evaluate the vegetative and productive performance of two soybean cultivars at different plant densities. Seeds of soybean cultivars (TMG 7063 IPRO and BS 2606 IPRO), recommended for the Alto Paranaíba region in the state Minas Gerais, were used and sown at seven different densities (8, 10, 12, 14, 16, 18 and 20 plants meter-1, equivalent to 160, 200, 240, 280, 280, 320, 360 and 400 thousand plants hectare-1, where they were evaluated in the development stages R1 (plant height) and R8 (height of the insertion of the first pod, plant height, number of nodes, number of branches, productivity per plant and productivity per hectare). The experiment was set up according to a randomized block design, in the factorial scheme A x B, being factor A composed by the cultivars and factor B by plant densities with three repetitions (blocks). Increased plant population resulted in greater first pod insertion height and final plant height, fewer nodes and branches and the average yield per hectare increased linearly, with the TMG 7063 IPRO cultivar being more productive under these conditions (52.7 bags of 60 kg per hectare).

The edamame is the soybean harvested in the R6 phenological period when the seed in green. That is the reason of its name, Green Soybean. To evaluate the influence of different planting densities and two types of potassium fertilizer on the agronomic components of the edamame cultivar BR 9452273, an experiment was conducted in the municipality of Boa Vista-RR between early 2015 and March 2016. The experimental design was a complete randomized block design in a 4 &times; 2 factorial scheme with four plant densities (140, 160, 200 and 240 thousand plants ha-1) and two forms of potassium fertilization in the last split-application (potassium chloride-KCl (control) and a Leaf fertilizer-K-20) on the same concentration (30 kg ha-1) for both treatments, with three replicates. Plant cultivation variables were evaluated, as well aspod productivity and the reproductive and maturation periods of the plants. Based on the results obtained, the BR-9452273 edamame lineage showed early growth and maturation under local edaphoclimatic conditions, with reproductive and maturation periods of 24 and 73 days after planting, respectively. Plant height and the insertion of the first pod, the diameter of the stem, and pod number in a sample of 500 g were affected by the joint action of the evaluated factors. Green pod yield and total biomass were favored by both higher and lower density, which alongside the application of KCl, were the most effective treatments for production of edamame in the Cerrado of Roraima.

The objective of the present study was to evaluate the presence of the herbicide 2,4-D in the Neosol. We conducted the experiment in a greenhouse using the soybean crop as a bioindicator. A randomized block design with 5 x 3 factorial scheme composed of five application periods before sowing (0, 3, 6, 9, and 12 days) and three simulated rain (0 mm, 20 mm, and 30 mm), with four repetitions was conducted. The herbicide dose was 1500 g a.i. ha-1, the rainfall was simulated one hour after pulverization. Twelve hours after the last rain simulation, Cv. TMG® ANTA 82 RR was sown, and pot moisture remained at 80% of pot capacity throughout the experiment. Herbicide in the soil was evaluated by visual plant phyto-intoxication, plant height, shoot fresh mass and root fresh mass, and shoot dry mass and root dry mass at 26 days after sowing. Statistical analysis was performed according to the polynomial regression model. The application of herbicides in dry soils that remained without rain during the first hours resulted in greater residual effect on the soil (0 mm of rain). The occurrence of higher humidity accelerated the degradation of the herbicide in the soil (30 mm of rain). Longer periods between application and sowing provided more significant increments. The herbicide’s toxic effects reduced linearly as started from 12 days before sowing. The 2,4-D showed low persistence in the soil, and 12 days was observed to represent a safe time length between spraying and sowing, regardless of the occurrence of rainfall. The soybean was a good indicator of 2,4-D.

ABSTRACT Castor bean grown at high plant densities can increase yield due to increased light interception and reduction in sink demand. The objective of this study was to evaluate the effect of plant density on growth of castor bean hybrids. The experiment was conducted in Botucatu, SP, Brazil, in a split plot randomized block design, with four replications, in 2011 and 2012. The main plot consisted of the sampling times and the subplots consisted of a 3x3 factorial, with the 3 genotypes in the first factor and the 3 plant densities in the second factor. The variables analyzed were: dry mass of leaves, stems, racemes, and total dry matter, which were measured at 30, 60, 90, 120 and 150 days after emergence (DAE). Data were examined for significant differences using analysis of variance followed by the F test (p < 0.05). When interaction was found between the factors and sampling the means were analyzed by regression analysis (p < 0.05). Growth performance was higher in 2012 because of the greater water availability. In 2011, under lower rainfall, there was less branching resulting in cycle end, with total leaf loss. High plant densities partially suppress the development of higher-order structures, especially when associated with water restriction.

The objective of this work was to study morphogenic characteristics, and dry matter production of roots and shoots of marandu palisadegrass (Brachiaria brizantha cv. Marandu) submitted to combinations of nitrogen and potassium, in a nutritive solution, employing silica as substrate. The experiment was carried out in a greenhouse during the summer. It was used a 5² fractionated factorial scheme with 13 combinations of nitrogen and potassium, which were distributed in a randomized block design, with four replications. The nitrogen × potassium interaction was significant for the number of tillers and leaves, for leaf area, for shoots and root section dry mass, for total length and surface and specific length and surface in the roots. Production of aerial part dry mass positively correlated with the number of tillers and leaves and grass leaf area. Nitrogen rates modulated the root system development, and the root specific length and surface decreased when high rates of nitrogen and potassium were supllied. Nitrogen and potassium influence Marandu palisadegrass morphogenic characteristics, which are determinant for grass dry matter production.

ABSTRACT: Cultivars of the genus Nopalea are known in Brazil for being tolerant to cochineal carmine attacks, thus making the cultivation of this genus a promising alternative for mitigating the negative effects of this insect on the production of biomass. With the objectives of characterizing morphologically spineless forage cactus varieties and identify morphological characteristics that may be the focus in spineless forage cactus breeding programs, an experiment was conducted in a completely randomized block design with 11 treatments and four replications. The variety Alagoas showed the highest values of weight, area and volume of cladodes. The varieties Negro Michoacan F7 and V7, Tamazunchale V12 showed the highest values of the cladode area index, the total volume of cladodes and total fresh mass production. The varieties Negro Michoacan V7 and F7 presented the highest water use efficiency and dry mass yield. Cladode volume showed the highest correlation coefficients with the fresh weight of cladodes. Aiming the release of varieties for biomass production, varieties Negro Michoacan F7, V7 and Tamazunchale V12 may substitute the Miúda variety. The number and cladode area index may be used as criteria for selection of superior varieties in breeding programs.

ABSTRACT Although there are evidences that the proper supply of mineral nutrients to plants relieves water stress, little is known on the approach of how the drought affects the absorption and accumulation of nutrients by distinct sugar cane genotypes, or in different parts of a same plant. Thus, the objective of this study was to determine the content and accumulation of N, P and K in the aerial part of plant from three genotypes of sugar cane, submitted to three water potentials in the soil, and check the relationship of these variables with the tolerance of plants to prolonged drought. In order to access this objective, an experiment under greenhouse conditions, comprised by a fatorial 3 × 3, in a randomized block design, and four replicates was carried out. After 90 days from treatment imposition, the plant transpiration rate, plant dry mass, concentration of N, P and K were determined in leaves and culms, as well as in total plant shoot were measured. It was found that tolerance to drought in sugar cane is related to higher levels of N and K in the leaves and stems, and larger accumulations of K and P in the plant shoot. There is high positive correlations among accumulation of N, P and K in the plant shoot and dry matter production by plants submitted to drought. There are intermediate correlations among plant transpiration and nutrient uptake by plants under drought. Plants of the genotype SP81-3250 are more tolerante to prolonged drought, than the RB855453 and IACSP95-5000 plants.
