Doses and forms of Azospirillum brasilense inoculation on maize crop

ABSTRACT In search of a more sustainable agriculture, the use of beneficial microorganisms has been highlighted, because they are low-cost and can reduce the use of fertilizers and increase grain yield. The present study aimed to evaluate the efficiency of A. brasilense inoculation and the best form and dose of inoculation in maize, measuring the impact on some physical characteristics and on its nutrition. The experiment was conducted in a greenhouse, in Ilha Solteira, SP, Brazil, in a completely randomized design, with four replicates and eight treatments: 1) control; 2) Seed 1x; 3) Seed 2x; 4) Soil 1x; 5) Soil 2x; 6) Leaf 1x; 7) Leaf 2x; 8) Seed 1x + Leaf 1x, respectively representing in each treatment the site and dose of application (1x, dose recommended by the manufacturer; 2x, twice the dose recommended by the manufacturer). No differences were found in any physical characteristics evaluated between treatments; however, for nutrient contents in the leaf tissue, there was effect on Zn content. It was concluded that, regardless of the presence of A. brasilense inoculation, forms or dose (in hybrid DKB 350), in general, there were no improvements in the characteristics evaluated.

Gypsum Application

Organic residue application is a low cost alternative to reduce the use of inorganic fertilizers and correctives. In order to study the effect of organic residues, limestone and gypsum application on phosphorus adsorption by lowland soils, four experiments were carried out. A Mesic Organosol (OY), a Melanic Gleysol (MG), a Haplic Gleysol (GX), and a Fluvic Neosol (RU) were used in a completely randomized design and factorial scheme (3 x 2), with five replicates: three soil amendment practices (limestone, gypsum and no corrective) and two levels of organic residue (with and without corral manure). Soil samples were incubated for 60 days, with and without organic residue incorporation. After this period, we applied the corrective and incubated the soil for 30 days, then P and basic fertilization (macro and micronutrients) were applied and the soil was incubated for additional 60 days. Equilibrium phosphorus, maximum phosphate adsorption capacity, pH, exchangeable Al and phosphorus-buffering index were measured. Organic residue and limestone application increased soil pH and reduced exchangeable Al, decreasing P adsorption. Gypsum application did not increase the pH but reduced exchangeable Al and P adsorption.

The carpel is the female reproductive structure composed of a set of stigma, style and ovary. Normally passionflower have three carpels, however, some cultivars have this structure in greater quantity. The objective of this work was to identify relationships between the number of carpels and the physical characteristics of BRS Gigante Amarelo fruits. The flowers with three and four carpels were marked, pollinated and the fruits harvested from these flowers analyzed for transverse diameter, longitudinal diameter, pericarp thickness, fruit mass, pulp mass, pulp ratio, number and weight of seeds. A completely randomized design with 10 replicates per treatment was used and each plot had the average of 3 fruits. The data were submitted to variance analysis and the means were compared by the Tukey test at 5% of probability. The fruits generated by flowers with 4 carpels were 18,30% heavier, their pulp were on average 20.75% heavier, presented transverse diameter 7,53% superior to that of fruits generated by flowers with 3 carpels. Similar increments were identified regarding the number of seeds and the weight of seeds per fruit that increased 18,85% and 52.42%, respectively. This result indicates that cv. BRS Yellow Giant with 4 carpels generates heavier fruits, pulp and seeds with a more spherical shape.

Sappan wood (Caesalpinia sappan L.) is a spice that has a high polyphenol content and has the potential to enrich the chocolate taste. This study evaluated the panelists’ acceptance and physical analysis (color and hardness) of white and milk compound chocolate with the addition of Sappan wood powder (0 %, 5%, 10%, 15%) by implementing a completely randomized design (CRD) experiment with one factor. The results showed that the addition of Sappan wood powder could reduce the panelists’ preference at the parameters of color, aroma, taste, texture and overalls. Hence, Panelists preferred white and milk compound chocolate without the addition of Sappan wood powder. Results of the physical analysis showed that the addition of Sappan wood powder decreased the chocolate brightness and increased the chocolate hardness.

SUMMARY The present study endeavors to determine the impact of the inclusion of licuri tart in the diet of finishing lambs, Santa Inês mestizos, by evaluating the economic parameters. For this purpose, a total of 44 lambs, including both uncastrated as well as vaccinated and wormed lambs, with an average age of six months and a mean body weight of 21.2 kg ± 2.7 kg, were employed. Initially, the lambs were fed on the diet which consisted of 40% Tifton-85 hay and 60% of a concentrated mixture, mainly composed of ground corn grain, soybean meal, mineral premix, being further followed by the inclusion of the licuri cake at four different levels (a) 0.0, (b) 8.0,(c) 16.0, and (d) 24% with respect to the dry matter. Principally, the soybean meal and milled corn were replaced by the licuri cake with these levels, thereby constituting four treatments and 11 replicates (11 lambs per treatment) in a completely randomized design. Further, for subjecting the lambs to the above mentioned four different levels of treatment, the lambs were confined for 70 days. The analysis of various economic parameters revealed that upon including the licuri cake up to the level of 24%, the operation cost decreases, which in turn results in higher profitability. However, its cost at the time of use will eventually determine its use for feeding lambs, because of the possible price variations of the ingredients used to formulate the diets along with the model of production of the rural property.

Biochar Amendment

A study was conducted to investigate the impact of biochar amendment on chemical properties and corn nutrient uptake in a sandy Podzol soil. Four rates of biochar (0, 5, 10, and 15 g kg−1) and two rates of inorganic fertilizer (0 and local recommendation rate for corn) were randomly applied to a completely randomized design with four replicates. Corn was grown for 45 d in a glasshouse using sandy Podzol. The increase in pH of the soil was concomitant with a decrease of exchangeable Al. The fertilized soil significantly increased total N, with a concomitant decrease in soil pH due to a N nitrification. Positive changes did occur in the soil due to biochar application, leading to a significant increase in dry matter yield and corn height. Corn N and K uptakes were significantly increased by the addition of biochar, but the same was not true for Ca and Mg. However, it was found that the concentrations of N, Ca, and Mg in the corn tissue were still lower than their critical level. Our results demonstrate that application of biochar alone is not able to supply enough nutrients for the healthy growth of corn.

O objetivo da pesquisa foi aferir as características físicas de cápsulas porosas para uso na irrigação localizada. Para o sistema de irrigação proposto, utilizaram-se dez cápsulas porosas na execução do ensaio experimental que consistiu em um delineamento inteiramente casualizado com três tratamentos, constando de diferentes manejos de irrigação (manejo via clima, via solo e via cápsula porosa) com dez repetições, totalizando 30 unidades experimentais, tendo sido avaliados parâmetros de produção e crescimento da cultura do rabanete. A pressão de borbulhamento média observada foi de 2,34 atm, enquanto a condutância hidráulica apresentou valor médio de 9,27 x 10-6 cm² s-1. Para a cultura em estudo não houve diferenças entre os tratamentos estudados, sendo que a massa fresca da raiz apresentou valores de 7,4 g planta-1 para o manejo via clima e 4,7 g planta-1 para o manejo via cápsula porosa, não sendo estatisticamente diferentes pelo teste de Tukey (p<0,05). O uso de sistema de irrigação por cápsulas porosas apresenta-se como uma alternativa viável para o cultivo de hortaliças em pequenas áreas.

PHYSICAL CHARACTERISTICS OF POROUS CAPSULES FOR USE IN IRRIGATION SYSTEM LOCATED 2 ABSTRACT There are different uses for porous capsules in agriculture, however they must be characterized by assessment parameters like bubbling pressure and hydraulic conductance. The objective of this work was to measure physical characteristics of porous capsules for localized irrigation use. For the proposed irrigation system, porous capsules were used in the execution of experimental trial, consisting of a completely randomized design with three treatments, different irrigation managements (climate management, soil management and porous capsule management) with 10 replications, totaling 30 experimental units, the culture chosen was radish, and parameters of production and growth were assessed. The average bubbling pressure found was 2.34 atm, while conductance presented values of 9.27 x 10-6 cm² s-1. For the crop study, differences between the treatments studied by the Tukey test (p <0.05) were not found; fresh root mass presented values of 7.4 g plant-1 for the climate management and 4.7 g plant-1 for management of porous capsule. The use of porous capsule irrigation systems is a viable alternative for growing vegetables in small areas. Keywords: Bubbling pressure, hydraulic conductance, emitter.

The aim of this study was to quantify the impact of two cutting severities on the dynamics of aerial and perennial (root plus crown) biomass of lucerne (Medicago sativa L.) plants of two cultivars of contrasting fall dormancy rating during the establishment phase. We worked at Unidad Integrada Balcarce with two cultivars of lucerne (non-winter dormant: FD10; semi-winter dormant: FD6) and two cutting severities (40 and 100 mm) defining four treatments (FD6-40 mm, FD6-100 mm, FD10-40 mm and FD10-100 mm) under a completely randomized design. In both cultivars, increasing cutting severity produced a reduction in leaf area and number of nodes in the residual, resulting in a reduced production of aerial biomass during regrowth, given a reduction on shoot number. On the other hand, the effect of increased cutting severity on perennial biomass was only observed in plants of FD10 cultivar. This cultivar showed less perennial biomass when cut at 40 mm than at 100 mm, while no differences were observed between cutting heights in FD6 cultivar.

Exfoliated vermiculite is a light-weight and cheap product that, because of its thermal resistance, has become a valuable insulating material. With regard to its use in beekeeping, this research tested whether the box for honey bees constructed with cement-vermiculite mortar (CVM) presents physical characteristics similar to those of wood. The experiment was carried out at Seropédica, RJ, Brazil, for eight months. The cement-vermiculite mortar was compared with a control material (pinewood), in the construction of Langstroth boxes and boards, in a completely randomized design, with respect to thermal control, thermal conductivity and its capacity to absorb and lose water. The production cost for a CVM box was estimated. There were no internal temperature differences between CVM and wooden boxes. Thermal conductivity values for CVM and pinewood were similar. CVM absorbed more water and lost water faster than pinewood. Since CVM boxes can be easily constructed, at a low cost and with similar characteristics as traditional boxes, made of wood, the material can be recommended for use in non-migratory beekeeping.
