This research was carried out in 2014-15 to determine yield and yield components of Azkan chickpea (Cicer arietinum L.) varieties with four different phosphorus doses and rhizobium bacteria in Van-Gevaº ecological conditions. The experiment was established as a randomized block design with three replications. The results of the research indicated that inoculation and phosphorus doses affected plant height, height of first pods, number of branches per plant, number of pods per plant, number of grain per plant and grain yield significantly. Grain yield averages ranged between 1556.10-1682.30 kg ha-1 in the first year and 1628.90-1677.30 kg ha-1 in the second year. When the results of inoculation and phosphorus doses were examined, the highest grain yield in both the years (1894.90-1867.70 kg ha-1, respectively) was obtained with 80 kg ha-1 phosphorus doses applied to inoculated plots. Increases in inoculation and phosphorus doses increased the grain yield.

Soybeans stand out among the main oilseeds in the world, with potassium (K+) as the second most required nutrient and exported by the plant. The objective of this study was to evaluate the effect of potassium fertilization on soybean crop and its correlation with the electrical conductivity in a Yellow Dystrophic Latosol in the Cerrado of Maranhão. The experiments were conducted in the years of 2015 and 2016. The design was a randomized block design, with five treatments and five replications. Treatments consisted of the following K2O doses: 0, 50, 100, 200 and 300 kg ha-1 in the sowing groove. The data collected were submitted to analysis of variance and regression. The response of soybean to potassium fertilization occurred for the mass of 100 grains. The highest grain yield was evidenced in the first year of soybean cultivation. The increase in the adjustment parameters of the regression models in the electrical conductivity of 20-40 cm in the second year of cultivation occurred as a function of the increase of the potassium fertilization.

The aim of this study was to evaluate the influence of planting density and cultivar of soybean on yield components in the southeast Amazon. The experiment was carried out in an Oxisol, with a randomized block design in a 2 x 4 factorial scheme. The treatments were two soybean cultivars (BRS 9090 RR and BRS 8990 RR) and four planting densities (13, 15, 18 and 20 plants m-1), with three replications. First pod insertion height (IFP), plant height (H), number of pods per plant (NPP), grain yield (Y) and weight of 100 grains (W100) were evaluated. The insertion height of the first pod showed a tendency of increase with the increment of plants per linear meter for cultivar BRS 8990 RR, different of the behavior observed for the cultivar BRS 9090 RR, which only showed difference when the density of 300.000 plants ha-1 was tested. For plant height, among soybean cultivars, there was only difference in D400, with BRS 8990 RR showing a maximum height of 83.3 cm, 21% higher than BRS 9090 RR. When evaluated under D350, BRS 8990 RR showed an increase of 13% in the number of pods compared to BRS 9090 RR. Both cultivars showed linear behavior for the grain yield, increasing according the plant population, with the highest grain yield obtained under the density of 400.000 plants ha-1 (4527.3 kg ha-1). The weight of 100 grains was not influenced by any variation factor.

ABSTRACT: The combination of herbicides and other pesticides can influence weed and crop management. This study aimed to evaluate the response of the combination of different herbicides with insecticides or fungicides of different chemical groups on the development and yield of wheat grains of the cultivar ORS Vintecinco. The experimental design was a randomized block design with three replications. The experiment consisted of 33 treatments, as follows: control without application and application of the herbicides 2,4-D (1,005 g a.e. ha-1), bentazon (756 g a.i. ha-1), metsulfuron-methyl (3 g a.i. ha-1), and pyroxsulam (16 g a.i. ha-1), isolated or combined with the insecticides chlorfluazuron (15 g a.i. ha-1), chlorpyrifos (720 g a.i. ha-1), deltamethrin (5 g a.i. ha-1), and methomyl (5 g a.i. ha-1) or with the fungicides azoxystrobin (100 g a.i. ha-1), carbendazim (250 g a.i. ha-1), and propiconazole (190 g a.i. ha-1). Relative tolerance (RT), shoot dry matter (SDM), yield components, and grain yield were evaluated. In general, pyroxsulam had the highest number of synergistic interactions with insecticides and fungicides, reducing RT and SDM, especially the combination pyroxsulam + chlorpyrifos due to a lower RT level (45%) and higher SDM reduction (52%). All combinations of herbicides with the insecticide chlorpyrifos and most of the combinations with the fungicide propiconazole led to a reduction of grain yield when compared to their isolated application or to control without application.

Objective was to evaluate the influence of defoliation of a soybean cultivar indeterminate growth in different vegetative stages on morphological characters and yield components. The study was conducted in the years 2010/11 and 2011/12. The experimental design was a randomized block design with seven treatments and four replications for each year. The treatments were: T1: No defoliation; T2: Defoliation in V4, T3: Defoliation in V4 and V5, T4: Defoliation in V4, V5 and V6, T5: Defoliation in V4, V5, V6 and V7, T6: Defoliation in V4, V5, V6, V7 and V8 and T7: Defoliation in V4, V5, V6, V7, V8 and V9. The variables analyzed were: main stem height, number and length of branches, first pod, number of pods per node on the main stem, and the branches per plant, number of reproductive nodes on the main stem, the branches, number of us total on the main stem, the branches, distance between us and grain yield. Grazing did not influence most of the morphological characters and increments the number of pods on the stem in years with good water availability and high levels of defoliation, and yield of soybean.

The investigations carried out in the last years showed that weather conditions were conductive to growth of chickpea (Cicer arietinum L.) in Poland. Our experiments started since 2000 on two cultivars Myles and Sanford. Evans replaced cv. Sanford in second year. The results pointed to the cv. Myles as generally healthiest and the percentage of infested plants was 3.2% in the first year and 0.92% in the next year. The experiment showed that the most important threats for plants during vegetation season were fungi from the genus Fusarium and Rhizoctonia solani, isolated most often from roots. The basal parts of the stems affected mainly Alternaria genus. Botrytis cinerea, Fusarium avenaceum and Alternaria sp. attack most frequently pods and seeds.

 The high cost of nitrogen fertilizers increases the expenses in pasture-based animal production. The inoculation with plant growth-promoting bacteria is an alternative to reduce the costs. This study evaluated the forage yield of Coastcross-1 pastures inoculated with Azospirillum brasilense, fertilized with different levels of nitrogen and subjected to cuts. The experiment was a factorial randomized block design with three replications. The factors were the inoculation (without inoculation, inoculated only at planting and reinoculated in the second year), levels of nitrogen (0, 100 and 200 kg ha-1 year-1 N) and seasons (spring, summer, fall and winter) when cuts were made. Forage yield, forage accumulation rate, botanical and structural pasture composition were evaluated. Forage yield without nitrogen fertilizer in pastures was in the first year 9.1, 11.7 and 11.7 t ha-1 DM, and in the second year 8.6, 11.2 and 11.5 t ha-1 DM, for the factor inoculation, respectively. The forage yield rises with inoculation at pasture planting, without nitrogen fertilization. Reinoculation is not necessary.
