The objective was to evaluate the application of foliar nitrogen in different doses and times, as a complement to soil fertilization. The work was conducted in a rural area of the municipality of Terra Nova do Norte – MT, located in the southern of brazilian Amazon. The treatments were a combination of foliar applications of nitrogen at doses of 0, 250, 500 and 750 mL.ha-1, and two application times with different intervals: 15 and 40 days after emergence; and 25 and 40 days after the emergency. The experimental design was a randomized block with four replications, in a factorial 4 x 2, totaling eight treatments. It was found that the variables green mass productivity and dried plant and ear and ear length responded positively as the N rates and application times. It was also observed that the foliar application of nitrogen increased the productivity of corn for silage, and better results are obtained from 750 mL.ha-1 of the studied leaf fertilizer. There was no increase in production factors when the foliar application of nitrogen was split.

Nitrogen is the most important nutrient for rice (Oryza sativa L) yields. This study aimed to evaluate the response of upland rice cultivars to N rate and application times in a randomized block design, in subdivided plots with four replications. The studied factors were five rice cultivars (BRS MG Curinga, BRS Monarca, BRS Pepita, BRS Primavera, and BRS Sertaneja), three application times (100 % at planting, 50 % at planting - 50 % at tillering and 100 % at tillering) and four N rates (0, 50, 100, and 150 kg ha-1). All cultivars responded to increased rates and different times of N application, especially BRS Primavera and BRS Sertaneja, which were the most productive when 50 % N rates were applied at sowing and 50 % at tillering. The response of cultivar BRS Monarca to N fertilization was best when 100 % of the fertilizer was applied at tillering.

The widespread selenium (Se) deficiency in soil and in feedstuffs from such soil, needs to be prevented by various methods. Recently, biofortification of Se has been carried out by soil fertilization and foliar application of crops. The aim of this study was evaluate the productive traits, Se status and blood metabolic profile in fattening lambs affected by Se biofortified corn. The research was conducted with 20 Merinolandschaf lambs of the average age of 70 days, during 30 days of fattening. The feed mixture of the control group contained corn (0.014 mg Se/kg dry matter, DM); in the experimental group (Se-BC), corn was biofortified (0.278 mg Se/kg DM). The feed mixture, hay and water were offered to lambs ad libitum. Blood was collected from the jugular vein on days 0 and 30 of experiment. Haematological indices were determined in whole blood, whereas concentrations of biochemical indices, enzyme activities, and concentrations of metabolic hormones were determined in serum. After the slaughter, samples of musculus semimembranosus, liver, kidney, lungs, spleen, peritoneum and heart tissues were taken. No significant differences were obtained in productive traits when feeding lambs with Se-BC. Higher concentrations of Se in lungs and liver (control: 0.26 and 0.75 mg/kg, respectively; Se-BC: 0.33 and 0.92 mg/kg, respectively) was determined in Se-BC compared to control. Higher activity of glutathione peroxidase enzyme in serum, higher erythrocyte count, higher content of haemoglobin and haematocrit in whole blood of Se-BC lambs were determined. The results of the study indicate the posibility of using Se-BC in lambs’ diets.

The objective of this study was to determine the best vermicompost dose for seedling production of Apuleia leiocarpa. The experiment consisted of five treatments, which were conducted in a greenhouse. The following doses of vermicompost were tested: control (without vermicompost); 10% vermicompost; 20% vermicompost; 30% vermicompost and 40% vermicompost of the total container volume (185 cm3). The experimental design was entirely randomised. The substratum used was bark of Pinus sp., which was triturated and composted. A hundred days after seedling germination, the following variables were analysed: height and diameter growth, above ground dry matter, root dry matter and total dry matter. The 30% vermicompost doses showed to be optimum in growth response and biomass production of Apuleia leiocarpa seedlings.

The purpose of this study was to evaluate the effect of different combinations of products applied through seed treatment, associated with the inoculation, in the development of soybean plants. The experiment was conducted in a greenhouse at Federal University of Lavras (UFLA). The experimental design was a randomized complete block, with four repetitions in a factorial 4 × 11, being four soybean cultivars and 11 combinations of products associated with the inoculation in the treatment of seeds. At the stage (R1) it was evaluated: plant height, leaf area, foliar chlorophyll content, number of trifoliate leaves, dry shoot mass, dry root mass, root length, root volume, nodules total number, viable nodules total number, nodules dry mass and foliar nitrogen content. The combination of products in the treatment of seeds, do not present phytotoxic effects in the characters related to the development, except for dry matter of aerial part and root volume. The combination of products in treatment of seeds influences negatively the nodulation, especially in the treatments with presence of nematicide. The inoculation performed in isolation or combined with fungicide and insecticide (I+FI) maintains nodule levels.

Wheat is grown in Brazil, mostly in no-till, a system in which the zinc can become potentially deficient, due to excessive application of acidity corrective and phosphate fertilizers in surface and, or at shallow depths. This study aimed to evaluate the effect of foliar application of zinc in agronomic characteristics and yield of wheat. The experimental design was randomized blocks with five replications. Treatments consisted of four doses of zinc (0, 54, 108 and 216g ha-1 Zn), divided into two foliar applications, the first at tillering (18 days after plant emergence) and the second at the boot stage (65 days after emergence). Foliar application of zinc increased the number of fertile tillers and yield of wheat, however, have little effect on the agronomic characteristics of no-tilled crop with high nutrient content in soil.

Nitrogen is the element most demanded by the soybean crop, and the biological fixation of atmospheric nitrogen is the main means to supply it. In contrast, micronutrients and chemical treatments applied on seeds together with the inoculant can alter the phenomenon of biological fixation of atmospheric nitrogen. This work aimed to evaluate the effect of chemical products, micronutrients, and nitrogen fertilization on the nodulation, development, and yield of soybean. The experiment was developed in a field and a greenhouse in the municipality of Toledo, Brazil. A randomized block with four repetitions was used as an experimental design. This design had eight treatments, namely: T1 - Control (seeds treated with insecticide); T2 - Seeds treated with insecticides and inoculated with Bradyrhizobium; T3 - Untreated seeds inoculated with Bradyrhizobium; T4  Seeds treated with insecticides and cobalt-molybdenum (CoMo), inoculated with Bradyrhizobium; T5 - Seeds with CoMo inoculated with Bradyrhizobium; T6 - Seeds treated with insecticides, inoculated with Bradyrhizobium and with foliar application of CoMo; T7 - Seeds treated with insecticides, inoculated with Bradyrhizobium and with the application of nitrogen in cover; T8 - Seeds treated with nitrogen by broadcast. No significant differences were observed between treatments on the nodules numbers, stem diameter, plant height, root length, the mass of 1000 grains, and yield. The application of nitrogen at the R2 stage (a plant with an open flower in one of the two uppermost nodes of the main stem with a fully developed leaf) and in association with the inoculant + CoMo without seed treatment provided a greater number of nodes, pods, and grains per plant.
